Ford 7.3L Power Stroke (1999-2003) :: 2001 Excursion Will Run Barely For About 20 Seconds / Shudders Then Dies
May 23, 2016
2001 Ford Excursion 7.3 will run barely for about 20 sec. shudders, then dies. Bought new, driven 334K miles. Performed the usual fixes common to 7.3 issues over the years. All original injectors except for #7 which I replaced about 5 yrs ago. (I know should have replaced in sets but not in the budget at the time). Anyway had my wife turn the engine over after I had removed valve covers for inspection and observed a lot of smoke coming out of what appears to be at or around number 7 rocker arm valley? All rocker arm/pushrods look to be moving as they should beyond that I'm in over my head. Am I screwed or could it possibly just be a bad injector/injectors?

I've done everything I can think of, ive replace the starter, batteries and altenator, both batteries have at least 12.30 volts when taken out and checked, but i turn the key and it will have power then try to start and whole system dies and wont come back on, I've cleaned the terminals and posts to shiny and the ground connections but its still not getting power.

2001 F350 7.3 ... Below 35 degrees, truck is hard to start. Cranks for a while, sputters, dies. Repeat a couple times, finally starts running rough, surging and loping for 10-15 seconds before it settles down and runs smoothly. Recently had all glow plugs replaced. Next cold start didn't show much improvement (not as bad as sometimes, but wasn't very cold either).
Surfing here and other forums, I see suggestions about letting glow plugs heat longer after WTS light goes out. Some suggest as long as 60 seconds. In the past, I have tried waiting a little while longer after light goes out, or turning key off/on and letting it cycle again. But I've never really timed how long I was waiting.
We're having a warm spell right now, so I can't do much testing. But yesterday morning was about 30. I timed the WTS light and it went out after 10 seconds. I waited another 20 seconds.. about 30 seconds total. Starting seemed a little better than usual, and there was about 1 second of roughness before it settled down.
I need to do more cold weather testing to be sure, but it does seem like it might be better to wait longer than I have been.
On the other end of the scale, I saw a comment that glow plug cycle is dependent on oil temp, and they don't come on at all if oil temp is above 40. Is this correct? If so, is there any good reason to wait to start in warm weather? I'm usually pretty diligent about waiting for the light regardless of weather, but the truck doesn't seem to object if I get impatient and start it sooner in warm weather. If the glow plugs aren't even on, why wait?
Should I just totally ignore the light, and wait for some interval (or not at all) based on a semi-educated guess about how much glow plug time might be necessary for the current temp?

I've developed a problem, usually when starting, that the truck will crank over, start and idle for a few seconds and then shut off. The few seconds it idles it doesn't get any throttle input. I'll crank it back over taking a little more than usual to get it started. When it does start it seems slightly sluggish but that quickly, like almost immediately goes away and the throttle is working again.
Oh, 2001, 7.3 stock w/200k

I have a 2001 Ford Excursion Limited 7.3l with 199,980 miles on it.
It has a TS-6. My first problem is that when I come to a stop or slow down to a crawl then press the accelerator the engine stalls and dies. I have looked and looked at threads and can not find this example anywhere. There is no pressing the pedal and it remains at idle. It dies, shuts off, quiets. I have thought icp, tps, ivs
Second problem is that a/c is blowing hot. Other than being out of Freon, what could be other things to check. It does sometime go to default, but has done so in awhile. It does not blow cold in rear and hot in front. They both blow hot. I have replaced the pvh sensor.

This is a 1999 with 200k on it. It has a really bad hpop so valley is full of oil. Haven't removed the HPOP to inspect the non serviceable plug or the hpop gasket. doing that this week. This truck I just bought and it has aftermarket injectors so dont know the miles in injectors. once the oil leak is resolved I can then give the injectors the once over to make sure theyre okay. Question is how much of a stream of oil should I expect to see as the engine runs?

My 2001 7.3 is smoking only when barely on the gas. New fuel filter. Don't know if its possible injector going bad or what? Smoke is white not black.

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!

My right front window would barely move when I was opening it. Binding real bad on the way down. So I pulled the door panel, ( a two minute affair ) lubed all the tracks with silicone grease. Now the window goes down very easily.
I had all four doors done in an hour. To remove the door panels, remove the red reflector from the door, remove the screw underneath of it. Gently pry up on the window switch bezel at the front for the front door, and the side for the rear doors if so equipped. There will be another screw underneath. Unplug the switch, remove the screw. Remove the trip piece from above the hinge area. Push up on the panel and it comes off.
I used that real thick silicone grease that you can get a plumbers supply for lubing faucet o-rings. It looks like double thick vaseline. Windows work like a dream now.

So I have had this occasional hiccup that has gotten more frequent. I figured since our weather has been extra cold (lows about 15 F, around 22 F in the morning), that the temperature had been contributing to the issue. My truck would hiccup and burp out some white smoke. At first it didn't throw a check engine or any codes. As of recently I would get a check engine light, but torque pro could not get any codes, they would be cleared when I cycled the key. Anyways, I finally got some codes yesterday because it happened again. The codes where P0603 and P0344.
So I ordered 2 new CPS from Riffraff yesterday (hoping that they will be here today so I can install one). Fast forward to this morning and i get the hiccup again except worse. Now my truck would barely reach 20mph and it constantly bucked. I limped my way to work (only 4 miles) and of course I got a check engine light but there were no codes that I could retrieve with Torque Pro again. I had read on another thread that the guy had an issue with a wire in the harness near the 42pin connector for the IDM. He replaced his CPS taped up the wire and it went away.
I'm at work and now I'm paranoid that I wont be able to make it home. Is there anything temporary I can do for the CPS, like maybe disconnect it and spray it with some contact cleaner, until I can replace it? I'm going to trace the wire harness to make sure there aren't any bare wires. I forgot to mention that the local stealership replaced the CPS for free due to recall less than 3000 miles ago...

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 am a new and very happy 7.3 owner. i have lurking around these forums and decided I didn't want to be a creeper anymore. So onto the fun stuff.
Yesterday my wife was exiting a freeway and the Ex shut off while exiting. once she came to a complete stop she tried turning it on and it would start then immediately shut off. she was able to turn it on and it would run then shut off as she drove across the intersection. once she made it across a good samaritan offered to park it for her. She noticed a little bit of black smoke but she told me that the guy was revving it to keep it running.
Luckily there was family at the mall and she waited for the flat bed to arrive. it sat for about 2 hours and they tried starting it and it would start then die. no more black smoke though. we had it towed to a diesel repair shop and they went to start it today and alas it started right up. they let it idle for 30 minutes and it was good. they test drove it and all good. they ran the codes and got the following:
P1876
B1352
B1483
U1147
One thing I did notice a couple of weeks ago, while driving on the freeway cruising about 65, the Ex surged a little and then ran fine. then another time it surged a little while idling. Some more info on the rig. it has a banks six gun tuner and has a cold air intake and exhaust. And it has a Banks Big Head wastegate. I bought the rig 2 months ago and changed all the filters and fluids.

I'm looking at a 2001 Excursion with 242k miles. Truck is all stock, and everything checks out well. The only thing is there is a slight vibration at idle, that increases quite a bit when the engine is revved to about 12-1500rpm. Ran a CCT, and #8 was flagged. I know that can be somewhat normal depending on the CPS, right? Otherwise the truck is smooth, and in great shape. Should I be concerned about what feels like a slight miss on #8?

I have a 2001 Excursion 7.3 Diesel that is having a starting issue. Have replaced the batteries, has new glow plugs, common failing cam position sensor replaced once already. It runs great when it starts, no codes. It will crank, but not turn over at random times. Will do this for 3 or 4 tries...charge the batteries, go back later to start and it will on the second try. Turn it off, try again..and back to cranking, but not starting. Not fun having to worry about being stranded somewhere. Absolutely desperate at this point.

The brief information:
1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.
New battery or alternator?

I know there are a few threads floating around regarding truck dieing, but mine is slightly different than the others, maybe its the same culprit, maybe not, but i thought i would start a new thread just in case.
First, I commute about 50 miles to work everyday, truck gets plenty of interstate highway run time, smooth as silk. About a month and half ago when i almost got to work I slowed to stop at a red light. As I came to a stop the truck "stumbled". Acted like it wanted to die but caught itself and kept going. I said whooaaaa girl, what this? Ive had this truck for almost 10 yrs now and never anything like this. About a week or so later, same commute, same red light, cept this time it dies. Starts right back up no problem. Just acted like someone turned the key off.
Then a week or so after that, while driving home this time, as I pulled up at the house to check the mail at the mailbox, when i came to a stop it died. Cranked right back up. Before I could put in drive, it died again. Cranked right back up and i drove on into the driveway. Then a few days later, while checking the mail again, it died again. Cranked up immediately and parked.
Today, while driving home, after i had gotten back to town, but before i got home i made a stop at bank drive thru, when i came to a stop, it died. While cranking it wanted to start and kind of stumbled on itself and died. Then it cranked right up and i came on home no problem.
So far it only occurs after approx 45min to 1 hr of operating time so the engine and everything else are at temp and far from cold. After reading thru some of the other threads of similar but different conditions (cold start dieing, dieing while under power, etc) Im getting flooded with ideas of what could cause it, but not settled on any.
1.Could be failing ICP? (original, has never been changed, 317k+).
2.Could be plugged fuel filters? (been a while since changing, approx 30k+)
3.Could related to one of my own earlier threads regarding possible failing alternator (when rpms drop can volts drop enough to kill engine?)
4.Could be loose ignition switch? (about 2 yrs ago i had to swap the blinker switch, to get to it had to remove the ignition. Upon re-installation the switch never did get tight as before and was loose. Been loose ever since. To the point that with key out of ignition and door ajar i will get the door chime as if the key was in ignition. I can bump the ignition, and chime goes away. Been this way for two years and no apparent problems. Until now maybe?)
I was thinking ICP after a few of the other threads, but after tonight Im leaning towards the ignition switch. I guess i can try to wiggle the switch after cranking tomorrow and see what that does for a trouble shooting effort. Is there a way to trouble shoot the ICP to see if its failing or not? Isn't that a fairly costly sensor? Would hate to buy one and not be the cause, but after 317k i may need to buy before too long anyway.

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....

I have a 99 7.3, I took off driving the other day and after about 10 minutes the truck just dies like I shut the key off but everything was still on. I tried to restart it and it would fire for just a sec then die. I set for about 15 minutes and tried again it fired up and ran about 5 mins then the same thing. I had a buddy hook it up to his scanner and it has a p0605 and another icp code.. We changed the icp then erased the codes.. Ran some rest through the scan took with the truck running and no codes so we took it for a drive made it about 20 minutes away and same thing but this time has the p0605 code again. Could the pcm be bad? I also noticed the electric pump is always on all the time it will cycle at least 30 seconds every time the key is turned??
