Ford 7.3L Power Stroke (1999-2003) :: F250 Will Crank / Hesitate / Start And Die - Code P0231
Jul 20, 2015
Okay, I am having issues with a 1999 F250 XLT 7.3 with diablo programmer. I have searched and searched and have tried everything we could think of and it is a no go. The truck will crank, hesitate to start, start and die, other times it will only crank and not run at all. We can make it stay running by hitting the accelerator. The only code we were getting was the cps code, but that is suspected to be because of the excessive cranking and no start times. Previous to this issue getting this serious it would stall randomly, at idle, going down the road at constant speed, slowing down, or accelerating. We now have code P0231.
Through this we have tried:
IDM
(loaner) ECM
removing Diablo
3 CPS
shaving down CPS
Shimming CPS
IPR
Fuel pump
relay
fuel pump fuse

I got a 2006 F250 6.0 that won't start. It turns over perfectly. What I've done so far was change oil and filter, along with fuel filters. All fuses and relays are fine. I payed for the scan gauge 2 and monitored FICM SYNC, FICM voltage, ICP, AND IPR. Every thing checks out besides ICP. The ICP is reading under 400. So I unplugged the ICP. Still no start.
I decided to spray some starter fluid in the intake and turn her over. Boom starts right up and runs fine. I even drove her around for about 20 min. I get home and shut off the truck. wait a few minutes and nothing dead again. So ICP is low but the truck runs fine after some initial support from starter fluid. What I need to do next? I don't want to have to take it into the shop for something stupid I could do myself.
Also the code its throwing at me is P0231 Fuel Pump Secondary Circuit

I have an electrical problem on my 2003 f250 7.3 diesel. Sometimes it starts and sometimes it doesn't (mostly doesn't). I have two new batteries in it and have cleaned the grounds at the batteries and at the engine. When I go to start the truck all the lights in the dashboard work and it dings at me but when i crank the key nothing. I wanted to see if i was getting power to the starter and when I put my multi-meter down on the ignition wire on the starter and put my ground lead on the chassis bolt it starts every time.....I'm thinking this should not happen?? Is that a bad ground or a short or something else?

I went on deployment and handed the wife to crank the truck up she did but didn't drive it so batteries didn't charge back up. I got them charged up and the truck cranked right up. I was plugging it in at night and it would start just fine the next morning. Then a week later batteries kept dying in a few hours during the day. Had to jump it again. then even when plugged in trying to crank it there was a buzzing noise and it would crank but not start. I bought new batteries and it cranked right up and drove fine until I shut it off and same problem and batteries were low again and it will crank but wont turn over. I am thinking maybe alternator.

But it starts. '99 F250 PS. Had code P1670, cleared it. No other codes. Started truck back up and ran KOER test with AE(which I'm not very good with). The code did not come back. It is hard to start plugged in cold or warmed up. I have WTS light and it goes out(glow plugs are original). RPMs are slow to come up (almost starts before it kicks in). Doesn't matter if fuel tank is full or not. Oil level is fine. Batteries are charged and check good. Starter checks out ok. Buzz test was ok. Now when I run KOER do I need to do anything other than hitting the initiate button?

I drove my 03 f-250 to work Monday everything was good no issues. At end of my shift truck will not start . turn key dash lights up glow plugs cycle turn to start nothing . Does not turn over. after some checking batteries are good. Starter will crank if i manually engage it but truck will not run even with jumping starter with ignition turned on . hooked scanner up says cannot communicate. Checked fuses etc fuse #31 has no power to it (trans range selector and starter relay)question is where to look next?

I have a 03 f250 6.0 had it for 2 years never had a problem. Last week I went out and started it to warm it's up as it is cold out here and it started fine I then noticed some thing hanging down under the dash so I started tucking it up under there and it arced and all gauges shut off and the truck shut off. So I took the panel down and it was the biometric pressure sensor that was hanging and the previous owner had a remote start on there that I never knew about and 2 wires on the sensor were stripped and not taped as well as some others. I checked all fuses and relays all working good tested fuse box and everything good there, replaced bio sensor and still nothing turn the key and try to start it and it does nothing injectors, don't precycle fuel pump doesn't run and starter doesn't kick in. I jumped starter off the wire on fender and it turns over but still doesn't start. Also I think it's the ecu but don't want to buy another one if I'm not sure if that's the problem.

I am trying to diagnose an issue with my 2003 F-250 6.0L PSD.
The first time I crank it everyday, it struggles to start. Beyond that, it seems to run fine and not have issues cranking throughout the day.
I've recently replaced both batteries, the FICM, the fuel filters and the FI wiring harness. What could be the issue?
The video shows exactly what I deal with every morning.

So yet another crank no start. Truck is an 03 55k miles The guy I bought the truck off of told me the turbo had been reconditioned about 1000 miles ago. Drove the truck another 1000 miles or so and now having issues. I went to start truck up and noticed it took awhile longer than normal to start up and when it did finally kick over, truck and no power at all. Would idle a bit rough sounded like no turbo spool at all when given throttle. Shut the truck off right and hooked up scangauge to it went to start it and nothing.
Did throw p2285 code ICP low circuit
Values read on scangauge are as follows:
FICM Main Power 48.0V
FICM Logic Power 10-8V
FICM sync is good
ICP Pressure 1540psi on crank
IPR duty cycle 14.8% Key on engine off/48.8% while cranking
At a bit of a loss as to where to look next, would really like to troubleshoot down to the right fix instead of just throwing parts at it. Have read after sitting the turbos tend to stick and need cleaned or replaced. After being cleaned only a few thousand miles could it be stuck again? Seems like I have spark, fuel, oil just acts like its not getting any air.

My 2003 f250 6.0l just up and quit. It make a popping noise out of the intake when cranking. I am getting 1150 psi at the icp and ipr is at 62% which seems high to me. The FICM voltage seem fine unless the batteries are drained and I am getting FICM sync. I replaced the HPOP, ICP sensor and IPR about a year ago. I recently replaced the air conditioning compressor and power steering pump. I am at a bit of a loss. I did pull the IPR and everything looked fine.

I have a 2001 f250 ext cab long bed 4x4 that I use as a feed pickup. I have had it for about a year now. one of the issues I have noticed since I bought it is the issue I am having with the flywheel/starter. Its very random like maybe I have a missing tooth or something on my fly wheel. but every so often when I would go to crank my truck over it would just make a little whirring sound and nothing happen ( like my starter gear isn't sliding out and engaging my fly wheel.
After looking through my inspection cover I noticed I had a little wear on the sides but no teeth to my knowledge broken or stripped off. I noticed my starter had one bold loose but other two perfectly tight. It was also covered in oil and dirt from my truck sweating horse power I decided to replace my starter and have my original ford starter rebuilt. I replaced it with a NEW oreillys starter. I noticed it cranked about 5 times as fast but again every 10-15 starts I am getting the same no start. any thing I am over looking?????

I have an intermittent security system issue. I sometimes get a dotted line in odometer and rapidly flashing theft light.
Crank no start. After a time, the theft light flashes a code of 1 then 4. Research gives me the result that PCM did not power up.
Have pulled gauges. Fixed known cold solder joint issue. Checked all connectors and reinstalled. Truck starts fine about 7/10 tries.
I have replaced battery terminals. Removed cleaned and replaced all firewall grounds. Checked harness connection blocks and PCM connector. Made sure all under hood fuses and relays working.
Currently sitting in a parking lot waiting for it to decide to start again. Only one chipped key. Where to look next? 1999 F150 xlt 6 cylinder.

I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.

I got a 2000 7.3l with 400,000 miles on it that decided to just not start anymore after I parked it for a couple days. Its always been a hard starter due to needing glow plugs but I can deal with that. it doesn't even try to fire anymore. I replaced the CPS (my tack bounces when cranking). The ICP has oil in the plug so I just unplugged it for now till I replace it.
I pulled the IPR and cleaned it really good and bench tested it with 12 volts and could here it clicking so I put it back in. I can get under the drivers door with the key on and hear the fuel pump running. I gain oil pressure on my dash gauge when cranking. I check all my fuses. my WTS light comes on . I just don't have any fancy scan tools to make this easier. Also just cause I was feeling lucky I just went out and bought 2 new batteries for it yesterday so we are good there.

I have a 1997 F350 7.3 with standard xmission. Have not messed with it since Oct of last year. Then it would crank but no start. Now when I turn the key there is no wts or nothing the gauges move, and tach moves when cranking, but nothing else.
The cam and crank pos sensors have been changed. The high pressure sensors changed. Now when I hook it to the AE it says cannot connect to truck. Where I need to start? Have checked all fuses that I know about.

Friend's 2000 7.3 wont start, just crank and crank tried to fire but nothing in the cold leave it plugged in and it starts leave it in a shop over night and it starts with a shot of either, he is a truck driver and the truck will sometimes sits for 6 weeks at a time this time 2 weeks before I touched it. He wanted me to install a fuel pump so I did and started the following:
Cracked fuel lines to see if I had fuel psi at both heads
I tested glowplugs they all read at 0.3 on all 8
I have power to harness as the same at both sides of the relay
RPM tach jumps
Oil psi gauge rises
Using my phone I can read hpop and 2000 at cranking (how accurate that is im not 100% sure)
All fuses good

So I got all 8 injectors upgraded and excited when I get them back I put them all in in kind of a rush. And in that rush I left the cylinders full of excess oil. So obviously when I tried to start it hydro locked. Angry at myself. I kept trying to crank hoping it would fire and just shoot that oil out. Nope, so I went back to taking all the glow plugs out and firing it all back out. Put it all back together then tried to fire her up. Took a minute but she started and I let it run for a while. Hit the gas a few times and then it died. Couldn't get it started again. It would just crank, I checked the icp and ipr and the icp did not build above 35 psi and the ipr was at 98.04% so I just figured the o rings blew out when it hydro locked.
So I took it all back apart put new o rings on, took my time and put it back together right double checking everything. Got it all back together and went to start it, it would just crank around 160-170 rpms, battery voltage at 10.6 icp built up to 140 but now it won't build past 40. Ipr still goes to 98.04. The engine ran just fine prior to injector change, I put a new upgraded hpop prior to injector change, new ipr, icp, cps. Everything checks out, but it will not build oil pressure while crank I've killed a set of batteries then went all out and spent 350 at napa for some optima red tops. I did notice the cylinder 7 injector is the AE injector. It suppose to be in cylinder 8, idk if that's affect the oil pressure building up?
But as far as I know, I'm not building oil pressure. So idk if the hydro lock could have ruined something to keep it from building oil pressure?

i have a 2001 f250 7.3L PSD. it turns over but will not run. replaced the CPS , starter and the #30 fuse. IPR is new and all injectors are new, new gaskets and harness and new glow plugs new batteries. still just cranks and cranks. no oil pressure build up and no tach movement, oil level is good in HPOP. What could it be?

So back ground is as such. Truck started fine before I replaced the hpop with t500 and did the driven diesel regulated return. I have double checked everything is plugged in. Now when I try to start it cold it will just crank. Yes I get smoke and oil pressure both places. If I give it a shot of ether it will start right up and run fine all day. What am I missing? Yes I know ether bad.

Found icp sensor with oil in plug and codes p1211 and p1212. Icp sensor reading 0 pressure. Changed out icp sensor. Still cranks no start check oil level in hpop resverior, check with brake clean spray nozzle and no oil on it. Filled resverior with oil. She tried to start. Had to put the charger on her and she finally lite off and came to life. Questions, how would that resverior empty out? Was it because I pulled that sensor? Is there s check valve in that resverior hanging up?
