Ford 7.3L Power Stroke (1999-2003) :: Truck Fires Right Up / Runs For 4 Or 5 Seconds Then Stalls Out
So I had a reman 7.3 and 4r100 dropped in my 03 excursion.. since then the engine fires up every single time.. ONLY when the truck sits for 2 days i have this issue where the truck fires right up, runs for 4 or 5 seconds then stalls out.. It starts back up on first try and idles rough 10 seconds then it runs great.. If it only sits 1 day i dont have the issue if it sits 1.5 days it will try to stall out and catches itself from stall out and doesn't stall about 3/4 of the time. The mechanic who is a reputable diesel mechanic cant figure it out.. they called swamps and they also were unsure.

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. ....

So I installed my chip today. It's got anti-theft, high idle, stock, 50, 75, 100 tunes.
With the chip installed the truck starts. In all tunes except "High Idle" it idles at about 1000... normally it would be like 500-600. High idle position works (1100-1200 RPM). Anti-theft position works - it kills the truck. The throttle does nothing when pressed no matter which position it is in. Stock, 50, 75 or 100.
I removed the chip and the truck runs fine. Did these guys send me one for an automatic? Or do I have the wrong computer in my truck? My computer code is DAC3 and the truck is a 2000 with a manual transmission.
Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Runs For 20 Seconds At Key On / Long Start Takes About 6 Seconds
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.

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.

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

I am a longtime 7.3 IDI guy with an 88 F350 crew so i know about diesels. But this is my first electronic diesel. I picked up a 2001 F450 2wd auto 260k miles. it used to be my work's truck but was stitting for a year and now i got it in "non running condition"
I towed it home and got it started by replacing the batteries and using the block heater.
As expected it took a few tries of long cranking to run the first time. runs pretty good and no smoke. what surprised me is it still takes about 5 sec of cranking to restart each time when warm too. any direction you would look with those symptoms? HPOP, IPR?
i am pretty sure the glow plugs all work because mechanics had replaced all that stuff. but i know back when the truck was last used it would still never start cold unless plugged in (even in summer).
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Truck Runs Rough When Cold
I have a 2001 7.3 with 259,000 miles. It does not get too cold here, however over the past few winters when the temp is below 50 at night the first minute or two of running out of the neighborhood is tough going unless I let it heat up. It has been getting worse over the past few years and now if its even 55 or 60 I need to let it heat up. Glow plugs? Injectors?
View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: Turn Over For 30 Seconds After Cranking / Engine Starts To Run Roughly Then Die
I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

I have a e99 f350 7.3 all stock. I have no power. The truck will crank for about 15-20sec before it'll turn over. I just purchased the*AE*but am fairly new to understanding it all. In idle its a little rough and when I drive I can only stay in the neighborhood because of fear of getting rearended due to very slow acceleration. Whats weird is that when i have no power while i am driving ill keep the pedal down throw it in nuetral and my rpms and*icp*pressure jump up right away. Things I've replaced:
Icp*sensor
Fuel pump
Pcm
Tps
Cps
Ipr
Dropped tanked and cleaned screens
When cranking my*icp*pressure climbs slowly to right under 500. I dont know what else to do ive been working on this truck dor two months some days 13hs straight, I am feeling defeated. Codes p1249 1211 1209....
Ford 7.3L Power Stroke (1999-2003) :: Truck Keeps Dying And Have To Crank For About 15 Seconds To Start Again
Alright, my 1999 7.3 keeps dying on me in the morning. About two weeks ago I noticed it started to have a weaker start up, even though it has two brand new batteries. Once it starts up, I get around the block and it dies there every time. Then I have to crank it for about 15 seconds for it to start again.
The crank gets faster and faster until it finally start, and the engine is very choppy, like its starving for fuel. After about ten seconds of that it return back to a smooth idle. I then take off, and about 50 yards later it does the same thing. After it does it the second time, the truck runs just fine for the rest of the day with no problems.
I have noticed that when if I turn the truck on and let it idle for 10 minutes first in the morning, it won't die on me. I replaced the camshaft position sensor thinking it was that, but it wasn't.
Ford 7.3L Power Stroke (1999-2003) :: CEL On - Long Crank / Truck Starts Losing Power And Eventually Died
On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.
Ford 7.3L Power Stroke (1999-2003) :: Truck Sounded Like All 8 Injectors Went Into Spaz Mode For About 1 - 2 Seconds
I was going to an appointment today and was going about 35 MPH and the truck just kinda sounded like all 8 injectors went into spaz mode for about 1-2 seconds. Initially I looked at the oil pressure thinking the oil pump went out. The engine/idiot light came on during the event and went off. But did not stall out in traffic. I was right in Green Bay Ugg that would have sucked.
I was a few minutes early and plugged in my Superchips reader to see what light code was there and it was a 1211. I have two questions for everyone.
1) Should I disconnect the ICP and check for oil, if so replace?
2) What hypothetically happened?
I now have a slight miss like a injector or something is not happy in one hole.

When I start my truck it takes 30 seconds or so for the truck to start moving... especially when in reverse. If I give it some gas it doesn't take quite as long. I am not a transmission guy. I assume it has something to do with building pressure but I don't know what would be the cause. The fluid is full and looks good.
View 8 RepliesFord 7.3L Power Stroke (1999-2003) :: Truck Starts Great And Dies When Hot - Codes P1283 And P1212
Truck starts great, and runs and idles fine until it warms up. This could be 15-20 minutes of driving or idling. Then it just dies. Like dead dies, lose power steering, everything (ac and lights still work, but no engine). It had died while idling, it has dies while cruising at 45mph. Then it will crank but no start. After about a 45min to an hour it will start like there was not issue, and pretty much drive the rest of the day (even after sitting) with no problem.
I installed the Adrenaline a few months ago, but the truck ran great for quite a while before this problem occurred. I did have it shipped with a rebuilt IPR. Tonight, I rebuilt the IPR with Guzzle's kit, and stripped it all the way down. Truck died again.
I have not had my AE hooked up when it died (stupid me today). But afterward I have been getting a few codes: P1283 (IPR Control Circuit) and P1212 (ICP lower than desired Engine crank or run).
When trying to start ICP duty cycle is about 64% and pressure is 185 to 190. If I unplug the ICP sensor pressure jumps to 2000ish, truck turns over faster and ICP Duty cycle goes to about 35%.
Ford 6.0L Power Stroke Diesel :: Runs For A Few Seconds And Stalls
My truck started fine my truck was running good. One morning while working from a hotel I went to start it in the morning and it started and stalled more than a few times but eventually ran fine later it did the same thing. The next morning it would not crank at all. I deduced it was the ficm and ordered a replacement the dash was acting funny and tach dropped before it died. I ran the. Test on the dash it swooped the gauges acted fine. I checked and wiggled sensors wires. I also checked were a splice at the crank sensor was it looked good then I bought a meter and the ficm seemed to have the correct volts it was a upgrade. Had 57volts at 1 screw koeo and while cranking.
PCM and replacing the crank and cam sensors. I don't really think it is the harness it will now crank and shut off crank and shut off like it did at first. He said it's stalling because it looses ficm sink. I haven't put new ficm on it ...the harness was allot better than the first. Could the crank sensor splice be wrong it is done its soldered together and heat shrink ... is it the ficm or the dash. I'm out of my comfort level I was also reading it only needs ficm sink to start. Not run. In addition #2 injector is throwing a code. I asked him if he thought the fuel was getting pressurized and his reply was the fuel has nothing to do with ficm sink. Also, I swapped relay out with my other 6.0. And its running fine This is everything I got ....
Ford 7.3L Power Stroke (1999-2003) :: Instant Loss Of Power But Runs
I am going along and the power just goes away. Sometimes it is a 50% loss other times it is an 80% loss. I hooked up my scanner and found an IPR code. I replaced the IPR and connector, nothing changed.
As the scanner info shows the Duty Cycle and Pressure track about identically until something goes wonky. When I loose about 50% power the pressure will not get above about 1500 psi but the duty cycle will run up to 60%. Other times when I have a bout an 80% loss the pressure and duty cycle both track low, no more than 1200psi and about 20%.
Ford Super Duty (1999-2016) :: Truck Starts Then Bogs Down And Dies After About 30 Seconds
Simple enough the truck starts then after about 30 seconds it bogs down and dies. I am getting these codes.

708 Transmission Range Sensor Circuit High Input
720 Output Speed Sensor Insufficient Input
743 Torque Converter Clutch Circuit
745 Pressure Control Solenoid Malfunction
