Ford 7.3L Power Stroke (1999-2003) :: Run Extremely Rough For A Couple Seconds Then Died?
Mar 6, 2016
Tried starting the truck, fired ran good for a couple seconds, then ran extremely rough for a couple seconds then died.
I did some research and changed the ICP because there was oil in the connector so even if it wasnt causing my issue i wanted to replace it.
Now I have the same issue but it will actually run a little longer and not stall. I thought it was fixed so i took it for a drive, after about 3 miles it bogged down and i was able to make it home with half throttle going about 30mph. Sounds almost like its running on half the cylinders. i unplugged the ICP and it continued to run that way.
I had done the 50cent mod a few years back with the peices from ford but i know the harnesses themselves can wear through so i checked the resistance between the center pin and the two pins to the right and left for both the injector harness and they had about 3ohms.
I am leaning towards an IPR but from the reading i have done it seams like most trucks will not restart after they die. I have AE so i am going to hook it up later today, just wanted some reccomendations on what to look at.
I also remember when i shut it off the unplug the ICP to see if it would clear up the needles on the gauges did a full sweep as if i disconnected the battery which i though was weird.

I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.

I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?

So there's no signal/ electrical feed to the passenger side cylinders. I ohmd all the UVCH and they check out. Moved the wiring harness around near the big black multi pin plug under the air intake to the turbo and the passenger bank kicks in and out so it's definitely a wiring short. Need links and pics to that multi pin plug to troubleshoot the wiring.....

Well, I was headed out from work this morning, on my way to fill up as I was a bit below 1/4 tank.
Truck was running good, like normal, until after 5-6 minutes, when it started running rough and had no power. Worried, I pulled off the side of the road. As I did so, it died, and wouldn't start again.
I whipped out my phone, pulled up TorquePro, and ran a code check. Nada. Well, it sounds to me like it's not getting fuel possibly, so I figure the best way to check, is to drain the fuel filter bowl, and crank it some, and check the bowl. No fuel in bowl.
Wifey came to pick me up with the can of diesel I keep for starting my forge (had 3 gal maybe?). Poured it in the tank, cranked it, no start. Still nothing in the bowl.
I'm taking her to work now, so she won't be late, then I'm headed back with a full can of diesel.
If that full can still won't get it, should I keep shuttling diesel cans, or should 8 gal or so be enough to get it back to the fuel pickup level? And if it's not fuel level, what else should I start checking on the side of the road?

I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

I need to get my oil cooler replaced but that's besides the fact. I drove it on a little trip the other night ran fine. Then went to start it after i was done with what i was doing turned it over didn't start the first time. Cycled the key and cranked it again. Started up drove it back home on the high way no spitting or sputters got off the high way it started idling like crap and shaking as i accelerated but made it home. Let it sit over night and day (was at work) got home to start it and it fired up no problem but still idled funny.
Revved it a couple times and it seemed to clear up so i took it around the block. Floored it and it ran like it was suppose to then go to the other side of the block floored it again and it had no power and sounded like it was running on 4 cylinders. Pulled it back in the driveway idled weird and cleared up again went down the street and floored it ran like a scaled ape and then just died. tried cranking it over and nothing finally got it to start after holding the ignition on ran and then died again. Got it pushed home and decided to fire again after a VERY long crank and it idled for a couple minutes very horrible and died on its own and hasn't started since.

This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.

My spine was damaged in an IED blast in Iraq a few years ago and my truck is getting harder and harder to drive. It sends every little bump up me. It looks like I have the original shocks on there.
What is recommended for shocks or possibly seat upgrades or any other possible solutions. I love my truck and don't want have to get something else.
The most I haul is my jeep on a trailer and occasionally two jeeps (8000lbs)...

My brother has a '99.5 with about 130k on it. It's extremely slow to startup even the the starter is spinning it over pretty quickly. I pulled my Edge CTS out of my truck to get some #'s off of his. At idle mine has about 700+ ICP, his has about 480. My IPR is about 14%, his is about 10%. The only other obvious things noticeable is that his oil pressure gauge takes 3+ solid seconds before it comes up. Once it's running, it's seems normal and ICP & IPR match mine under full acceleration. The only other thing that is odd, while cranking his volts drop to mid 10's but isn't turning over slow. Where to start?

Yesterday my truck began to give me some problems starting. The engine turns over just a couple of times then it sounds like the starter disengages and winds up. it took multiple attempts but it finally fired up. Does this sound like the starter or could it possibly be the starter relay?

On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

If I leave my truck sit for a couple of days, the batteries are noticeably weaker. It's fine overnight, but two nights and it's slow to crank. Three and it won't start without charging the batteries. I checked for a drain last night and found that it was drawing 1.2 amps.
That seems like a lot, no?

I am a cummins owner who just got a 2002 7.3 last week. It drove great for 200 miles then suddenly died last night going 60 mph. It sat overnight then started up and drove 10 miles then died again. I changed the cps and still no start. I changed the oil and let it sit overnight and it started this morning and idled for 5 minutes then died again. I have tried unplugging the ipc and still same no start situation. I plan to check the hpop level today to verify it is full. I also checked the nut on the ipr and it's electrical connection.
I am just a shade tree at best and would love some direction on where to look. I don't have any scan equipment to check pressures. Am I correct in thinking it is a bad ipr?

I have a 2002 F250 Super Duty. Was driving it and it started to lose power and shut off. Then wouldn't start like out of fuel. No engine light no codes. Truck has 155k on it. So just because I replaced fuel pump. Truck runs but not right it's ruff no power kinda back fires in exhaust. I check wires and plugs under valve covers all seems ok. I ran truck and pulled each injector loose and engine would stumble. As in they are working. I replaced cps. Just because still the same. Then the truck started running right. But the truck runs but has knock but knock goes away and truck has full power. Yes oil is full and I change it regularly. The problem is off and on like electrical.

I have a 2003 F350 SD FWD Dually With 4.10 Axle Ratio. I'm looking for some front rotors and pads and I'm looking for recommendations. I tow a 44' Goose neck racing trailer on a regular basis so I dont want autozone crap rotors that are going to warp in a few thousand miles. I was on rockauto.com, they have Wagner, Bendix, Motocraft, Powerstop, etc etc. I thought maybe those Powerstop drilled and slotted looked interesting, but I dont know much about them.

i just bought my first diesel truck, a 7.3 of course. 2002 f350 4x4 crew cab, short bed. Any ways i drove it for like 2 weeks and left it at my uncles house so he can use to go to work. then 2 days later he calls me to tell me that the truck shut off while driving just like that. he tried turning it on a couple of times and it would just crank. he gave up and had it towed. I have been looking through all power strokes forums and found some solutions like changing the CPS or the IPR.

Jumped in the 1999 cc dually 7.3 6 spd superduty.
Just rebuilt the rear locker ( FYI if you use new clutches Do NOT add clutches, it is TOO tight now) and rest of rear end.
Full of fuel, drove it half the day only minor issues. Cruise, Horn, 4x4, suddenly would not work, but it was running and driving like it always has.
Around lunch while at 55 mph it shuttered hard like it had stalled for a second. I stopped and checked the oil. It was just above the add but I topped it off and went one. The further I went the more it happened.
So I decided to head back to shop and switch it with the car i had left there. It finally died like it was out of fuel.
next day I take 5 gallons of fuel and put in it ( maybe the gauge is acting up like the horn, cruise and 4x4?), it brings it from 3/4 plus to full mark, so gauge is working accurate. I also keep a fuel log that says i went 100 miles since last fill up.
Get in, it fires right up. I leave it sit and idle while i park the car. About 5 minutes and it dies. It will start run a few seconds and die again. The more I try it the shorter time it runs.
Finally does not want it start at all. I read about disconnecting plug on inside left front of valve cover , that had not effect. Crawled under, and frame mounted fuel pump is running.

I have had this truck for a few weeks. I do not have a good history on this truck. the guy I got it from did not seem to know much about it. He got it from a local retired painter. It has 230K on it. It seems to run and start OK. So I got up and decided to take the truck because I'm trying to determine if it reliable or not. Its about 45F. It starts fine and idles fine I'm cleaning the windows.
About the time I'm done the idle speed slows sightly it shudders a bit and stops! I try to restart is a bit. No sign of life I take a car to work. After work it's about 68F, I open the fuel filter to check for fuel. That makes a mess! I clean it up the mess and she fires right up. I take her for a little spin everything seems fine. The CEL never came on. What do you think? I figured fuel from the way it died, but after work she fires right up. I do not want to get stuck on the way to work!

Ok so this past Saturday I drove the truck about 40 miles round trip to get fuel and came back to the house to pick up my tux for a wedding I was in that afternoon. On the way to the wedding I went about 10 miles down the highway doing about 65-70 mph and all of a sudden I heard the engine just shut off. No stutter or anything.
Went to restart and nothing just cranks. had to call and get a tow back to the house real quick and grab the excursion and head to the wedding. When I got home on Sunday I hooked AE up and started to poke around.
RPM around 150-170
Batt Voltage 11.5-12
IPR up to 65%
ICP 0 (have tried to unplug and start) (sensor is dry no oil bleed through)
Buzz test is good all injectors are strong. I am sure it is the lack of oil pressure but I dont know why. I can get more info from AE if needed.

So I'm on my way out of town, when the truck just doesn't feel right. I proceed to make a u turn and pull off the high way. During the course of the u turn the truck shuts off. I pop the hood and notice the oil is everywhere from the fuel bowl back. Oil is also dripping off the passenger frame rail.
There is also a nice size puddle of oil pooled under the truck. I believe that I blew the high pressure oil line that feeds the injectors. I had to get towed back home. If it is the high pressure hose, how much does the stealership normally charge?
