Ford 7.3L Power Stroke (1999-2003) :: 1998 E450 Ambulance - Hard Cutout When Cold
Apr 14, 2016
Here's my video of it doing it: [URL].....
98 e-450 rv cutaway with the 7.3 PSD. 219k.
Here's what I have done so far
-New GPR
-New Glow Plugs
-New CPS
-unplugged the PCM, and re-plugged
When it cuts out like the first time in the video, the accelerator pedal does nothing at all. Then once the WTS and CEL go off, it's fine again for a bit.
It seems to only do it when the engine is cold as well. After I had driven it around the block a few times and let it idle, it got better. I was able to drive it 20 miles round trip without it cutting out.
Also, might be related, it has been random on power since I got it. Sometimes I have to floor the accelerator to get up a hill, sometimes I barely need to touch it.
What to check next? It's hard to tell if it's de-fueling or if it's an electrical issue.

I bought this 16' box truck today. 7.3L, 213k, 2003. It doesn't start and the owner gave a really good bottom dollar deal for all these reasons. Showing up armed with Torque Pro and my bluetooth adapter, I proceeded to plug it in and check for rpms, HPOP, Battery voltage, etc. No power to port
Find fuse diagram the owner located and fuse 23 is the OBD port. No fuse in place. He found us a fuse, I plugged it in, viola! Power to the port, TP is in action, ready to troubleshoot.
"Charged" battery, start cranking...no start. No Torque Pro (!) Apparently, the OBD port is cut-off while cranking .... Is there some other fuse or connection that will keep it connected during cranking so I can check for RPMs (no dash gauge for it)?
As soon as I left off the starter, the HPOP on TP showed 1212 then 850, then continued to drop with in about 2 secs. I figure it is getting good HPOP and this is the momentary bleed off.
PO replaced some time ago CPS with Autozone or something in an attempt to start it. No go. I am going to take my "emergency" CPS next time to see if that does it.
Because of the cranking-cutout, I cannot see FIPW. No way to know if the injectors are firing. It had reportedly been running a short time ago (weeks maybe?) and shut off while parked in the parking lot and never started again.
Batteries are low, but new-ish starter and cranks well. With jumpers, able to maintain 10.8v or so while cranking, though it was a bit up and down. I'll take a strong charger with 200amp boost mode next time.
Fuel pump runs. I can feel/hear it when the key is cycled. It has standard Rotella 15w-40w on this 50F day. Reportedly *wants* to be plugged in to start. I plan to switch to 5w-40w synthetic as soon as I can get it home.
It's automatic, pretty sure all van/stock. Here's a pic. Dog box gives good access to turbo and such, but everything else...
One battery under hood, other under cab/body. Has green antifreeze and leak at thermostat.
My goal is to get it running to get it home, about 30 miles, then replace ICP, CPS, IPR, Glowplugs (relay already done), thermostat and top housing and hose, convert to lifetime antifreeze, oil change to 5w-40w synthetic, 2 batteries (test alternator), uppipes or gaskets, Air filter (what upgrades available for this?), UVCH, idler pulleys and belt, replace trans fluid and filter, couple tires, paint inside box, weld and reinforce rear bumper, add radio, check cigarette plugs (think cell phones and gps), general cleanup.
I will have it and run it around 30 days. If it is solid and reliable, off to West Virginia it goes. If not, I'll part it out to get back what I can from it. I am paying for it up front, they are raising donations. But I won't let them pay anything (costs only) for it until I'm satisfied.
They need to run it about 5hrs round trip once a month immediately. That's about 3k miles per year. But I'm sure they will find lots of other uses, such as building supplies, etc. I'm hoping the injectors hold up for a while.
Right now they have multiple vehicles, trailers, drivers donating their time and vehicles (reimbursed for fuel only). It would be much better to take one hauling truck and one or two passenger vehicles... hence the box truck idea.
They distributed approximately 100k lbs of food last year. Not refrigerated, not needed. No CDL needed, about 14k GAVW. The PO has offered his carport where it is parked now, or even to push it into his garage with limited tools (I can bring some) to get it to run. Otherwise...
How to get this home?? Too heavy for my buddy's tow truck from the front. Wheels too far from back of box to reach them from the rear. No tow loops in front for tow bar, UHaul dolly rated at 4k (maybe?)
Dual rear wheels. Anything else I'm missing?

I am a new diesel owner. So I'm not too familiar, how to trouble shoot. I am however, pretty familiar with working on gasoline vehicles. I have a 1999 E-450 Shuttle Bus that will not start after parking it for just 3 days. I live in the area where weather has been above 90 degrees each day. I've charged the batteries, replaced them, and boosted, still no start. I have fuel coming in the bowl. And the battery meter on dash is showing that I'm cranking at around 14 volts.

I have no ground to glow plug solenoid, wiring is ok right up to the computer. Where I should go from there?
Its a 2001 E450 PSD. glow plugs not coming on at all.
should I be checking an engine temp sensor?
I don't have a wiring diagram so I am going in somewhat blind. ]

2000 Ford 7.3 E450 120,000 miles...
I have changed the CPS twice
I have checked the resistance of the injectors at the IDM connector with a volt meter and the harness reports back good.
The truck will run with ether for a few seconds
I have changed the fuel filter.
The fuel bowl fills quickly
I have unplugged the ICP.
The truck is showing low voltage on the gauge with a good battery. Around 10v
I have connected my 200amp car starter and I never see over 10v. I plan to check the grounds, but I am at a loss.
Everything is difficult because this is a van body so space is limited. I have also plugged in the block heater for an hour and that hasn't made any difference. Where can I get the best price on an AE scanner.

My truck is hard to start when cold and I suspect glow plugs. But it is not showing any codes? If it is a glow plug or glow plug relay at fault , should it throw a code?

We're currently RV camping in the Wyoming Wind River Range at 8500 ft and is getting to freezing at night. The past two mornings the truck has been very difficult to start and I got quite a bit of smoke. This morning it took two or three tries but I got it going.

When it is cold out side like 20 degrees I'm having problems starting my 2000 7.3 I'm cycling it about 5 times and misses smokes white for a bit then stays running I was thinking of changing out the fuel filter. What it could be?

It's been a while but thats because the truck has been performing well.
Current problem: The truck has been hard to start this year as if the glow plugs are not working or are bad. It will start right up if I use the block heater.
Just recently, I also noticed that the EBPV is not coming on when warming up the truck.
Also, This winter season, the engine temp is not coming up to normal. the engine temp needle is more on the low side towards the C and definitely less than 1/2 way up where is normally is. When driving on the highway, the temp comes up more. but sitting at idle it barely gets warm.
So not sure if all 3 are related or not, but looking for a starting point.

20 degrees out this morning truck not plugged in, didn't want to start had to cycle 4-5 times, each time waiting for glow plug Light to go out.
Finally cranked didn't sound pretty but cranked. Once it started idling on its own got out and seen a puddle of oil under the front of the engine drivers side center kind of.
Got up on the truck and shined a light in the valley and seen a puddle in intake valley. Heres my question? Where did this oil come from? Once it warmed up it quit and oil kinda disappeared from valley???
I had turbo off a few months ago because I thought I had a bearing down in it, but found some bolts lose. When I put turbo back on I broke the wire plug on front of the pedestal so I just left it unplugged. Very hard to cold start now that that is unhooked.
Did leaving this unhooked create a hard cold start? Should I put another pedestal on it with the plug or install one without it? Also will it hurt to leave plugged in overnight?

2003 F350 7.3L 164k miles. Got towed in with hard to start cold complaint.
Hooked it up to the Snap On Verus Pro scan tool and we get up to 3000 psi on the ICP cranking, IPR value seems within spec, we have rpms over 100 on tool, pulse width within spec, computer voltage above 10v while cranking, verified output of glow plug module (California) and glow plugs get voltage for approx 50 seconds @ 80 degrees farenheit, glow plugs all read 0 ohms resistance.
injectors do NOT sound the same during buzz test.
Vehicle takes EXCESSIVE cranking cold to eventually get it started. LOTS of cranking. Just had to replace starter and a battery because driver burned em out. It feels like the vehicle shakes when it gets running. Black smoke when revving cold. Sometimes white smoke while cranking.
Once the engine has been warmed up, it starts perfectly every time.
I have spent two days in the engine bay looking for chaffed wires and doing diag and my current diagnosis is bad injectors. I feel there COULD also be high pressure oil leak, or a mechanical issue such as low compression. No compression guage yet for this truck. We have the ICP and IPR fittings to do a shop air test. Recently did a 6.0L and went thru everything and eventually diagnosed it as bad HPOP. LOW ICP pressure.
I noticed two of the cylinders were at maybe 8% Perdel on the data. Seems too high. Also, it "passed" the KOER self test and "passed" the injector buzz test with no codes after, but the audible sound of injectors didn't "seem" right to me, but I am new to these engines.

My 1999 F550 7.3L has been hard to start when it's cold outside since I got it with about 150k on it (it has 200k on it now). Last year we tested the glow plugs and sure enough 5 of 8 were bad. So they are all new now. It worked a little with the hard start, but not much.
When it's cold out the engine will crank forever amongst clouds of smoke and the smell of unburnt diesel fuel and sometimes eventually start, followed by smoke and sputtering until the cylinders clear out. However, what I have noticed recently is that it will sometimes start in the first few revolutions. It seems like the best way to start cold is as follows:
1. Let the glow plugs heat up for a minute or two,
2. Crank engine for 10 or 15 seconds and stop,
3. Crank engine again, but stop if it doesn't catch in the first couple of revolutions,
4. Repeat step 3 until engine starts.
When it starts using this method, it's immediate and it's running smoothly immediately with minimal smoke. This is making me think there's a computer or sensor issue, but I have no codes.

I have a 2002 f350 that has had cold starting issues since I bought it. I have replaced the glow plugs twice, the glow plug solenoid four times. When I put a new solenoid on it it works fine for a short time. I know the solenoids are bad because I get battery voltage on one side and nothing on the other. If I jump the solenoid with a jumper wire I can get the truck to start. I thought I was getting bad solenoids but I have recently tested the activation circuit and am getting constant power there. I.e. It never shuts off. I think this is what is causing the solenoids to burn up. From the tracing of wiring diagrams I have done, the only thing before the solenoid is the Pcm. So now to the question,
1) What controls the activation of the Glow plugs? Is there a temperature sensor or something before the Pcm.
2) Is this a case of my Pcm going out on me? I am a mechanic in the army so I have a decent understanding of mechanics.
However I am at a loss for these systems.

I have a 01 7.3 crew cab dually and it's had cold start problems since i got it in 09.I have replaced everything i could think of including glow plugs gpr,harness and batteries. Any temp below 40 i have to plug it in . If i cycle it 3 or 4 times it will start but it smokes and runs ruff. My 00 7.3 excursion starts up down to about 10 degrees than i have to plug it in so i know dually is not right.
I have a afe intake,1.5 injectors, driven diesel rr, adrenilin pump,dp tune by gear head. Kinda at wits end don't mind plugging it in in dead of winter but now one night it's 30 next it's50 and i don't have to . Also have fully built trans by level 10 if it matters .I get battery light coming on every now and again. New alt about every year and a half.

2002 Excursion, 7.3L 375,xxx miles ... As the weather is cooling off, my excursion has a starting problem for a few years.
Replaced all the glow plugs last year. We (my brothers and I) thought it was injectors, but in the summer time or if block heater is plugged in, she starts normally and idles smoothly. And no smoke and runs fine once she warms up.
When cold, it acts like 1 or 2 injectors are not firing. Have run all kinds of cleaners through the oil and fuel.....
Don't want to swap injectors just to swap parts. Would like to diagnose problem....

Truck is a completely stock 2002. New injector o-rings, glow plugs, valve cover harness, and injector cups a year ago... all motorcraft parts. New batteries and starter in the last 6 months.
I've checked the GPR both at the relay and harness got power all the way to the valve cover harness on all 8. Injector buzz test sounds okay as well.
Had a stuck IPR issue a few moths ago that caused a CEL and died while running. Took apart and cleaned the IPR and CEL is gone truck runs great once started and has correct IPR pressures in all RPM ranges.
Truck runs great once it is started and is not sluggish until warm like when it was hard to start when cold with leaking injector o-rings.

This is an issue I started chasing after having all the injectors replaced on my aunt's F-350. We had them replaced due to hard/no start on cold (dealership told her they needed to be changed). Unfortunately, I did not get the buzz test results before changing the injectors.
So far that has been replaced:
Injectors
ICP (was leaking)
IPR
both UVCH
IDM (twice)
The issue we are having right now is that only 2 injectors (#6, #7) buzz properly. Initially when we changed the injectors, it did start but didn't seem to run quite right. We did the buzz test and at that time and injectors 1,3,5,6,7 would buzz strong but the rest were weak. After some forum lurking, we suspected that the IDM was faulty. We purchased a refurbished one and after we changed it, only injectors 6,7 would buzz strong. Thinking a faulty IDM was sent it back for a replacement. While waiting, we decided to put the old one back in figuring it would go back as it was before but only 6,7 would buzz strong. We receive the second IDM and same thing, only 6,7 buzz strong. We did a continuity test from the IDM connector and they all get 2.7 ohms (it was an older multimeter so not sure if being .1 under the 2.8-3.6 range is bad).
What I did next is use the uvch external pigtail to test the injectors. I plugged the extra pig tail into the uvch and then the ends of the wires into the plug of the upper harness. Afterwards, I would swap a different injector wire (on the pigtail) to the #6 injector wire (on the upper harness). Whatever injector that would go to #6 would fire correctly. So I know that the injectors themselves are fine. I am suspecting the wiring harnesses (upper/lower) but the continuity test would say otherwise. We also do not get any fault codes except for the EBP occasionally (waiting for a new one). I am lost on what to test or look at next.

2003 Excursiom 4x4 Limited
My first Diesel. Runs and drives great. Torque Pro app only showed coolant temp at 188. Would not show oil temp. Hard to cold start. New injectors. Has a programmer. He is asking 12K. It has 209K miles.
It belongs to a friend of mine and he rarely drives it. It stays under a cover most of the time.

My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.

Iam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.
