Ford 7.3L Power Stroke (1999-2003) :: Shut It Off Warm And It Won't Fire Again
Nov 11, 2016
E99 zf6 180k. Ts 6 position and 6637. Just found d out the oil was 25000 miles old and changed it. 400 mile trip followed by a few days in town with no problems. Shut it off warm and it won't refire. Takes 3 loooong cranks. Few minutes later it restarts hard but not as hard. Head out for a few hundred mile trip and it's running fine except all of a sudden "bucks" a few times within a couple hour window. I took data during the trip and never saw anything strange. Today a cold start, around town driving, and warm restart were all normal.
My thoughts are to
1. Verify steady fuel pressure (I only have a temporary gauge setup)
2. Check the fuel filter for oil.
3. Pull the valve covers to look for injector oil leaks.
#3, though, I dunno if it's worth it. Perdels look fine and icp seems to be about the same as it always has.

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??

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

My dad has a 99 F250 with a no start issue. Everything was starting and running fine one day. The next he gets a no start. Cranks fast and fine but wont fire up and start. He has a scangaugeII hooked up to it and his oil pressures and volts look fine. His tach moves when he is trying to start it. He checked the icp sensor and it had oil through it so he replaced it with a Ford part. Unplugged it and the scangauge pressure goes up but no start. He also replaced the ipr with a new Ford one just in case. He checked and is getting low pressure and high pressure oil. I am having him check the fuel heater fuse #22 to make sure it is not blown. He had the block heater plugged in all night along with a battery charger to make sure they are topped off as well. We have gone through a couple of the checklists on this site for a no start condition but nothing has solved it yet. If you need any info off the scangauge let me know and I will post the exact readings. I think he is sitting at about 200k on the motor. No major issues or problems until now. He is currently also pulling the ICM to check it out as well. No codes are being thrown.

I am having trouble getting my 2000 7.3 (200k) to start on the colder mornings. It will crank over fast, but won't start without a lot of tries. Today it took 6 pre-heats and cranks, but on others (and colder days) it has started easier. It does seem to be getting worse though.
I have replaced the glow plug relay recently so it *shouldn't* be that unless the replacement is fried. Starts fine the rest of the day and drives fine, but not in the cooler am (it was about 34 this morning). I also tested the batteries yesterday and while they aren't new, they tested okay.
Also, I read (briefly) about the CPS, but forgot to watch the tach this morning, but did notice it is pushing smoke out when turning over.

Lately sometimes when I get in and start the truck all is well. Then the next time it will spin like a top, but not fire. New batteries. Then it will fire right up. It may go a few weeks, or days, then it happens again. Temperature does not seem to be a factor. It also doesn't matter if the engine is hot or cold. Once when rounding a corner at low speed, it just died, then started right up.
I recently changed the fuel and air filters. I think the glow plugs are getting old. In cool weather I turn the key on for about 1 min. before cranking. I have 110,000 on the engine with all original parts.

2002 7.3 Power Stroke... I bought the truck about 4 months ago and I absolutely love it but over the last few weeks is has been acting funny at times, it doesn't do it all the time but it has been getting progressively worse, ill drive the truck all day and no problems when I shut it off and go to start it again it just cranks but won't fire.
* Batteries are charged and in good condition, oil is a little dirty but full, I have no codes or check engine light on, and my wait to start light seems to be working fine!
* If I supply a fuel source(starting fluid) the truck will fire but not stay running
* And let it sit for 15 to 45 minutes fires right up like there was never an issue.
* There are no blown fuses

I just replaced my up pipes, turbo pedestal O-ring, ICP, IPR, New O-rings in all my injectors and torqued to spec, new glow plugs, glow plug relay, oil loom wiring harness, new O-rings on oil cooler, oil filter, oil, and antifreeze. I have tried and tried on upwards of 75 or so time to get it to turn over. A little white smoke came out and it sounded like it wanted to fire up, but only a few times.
I have good batteries and a charger on it, 3-4 tries in 5-10 second bursts or longer if it doesn't lose power every 30 -hr. oil is in HPOP too. just found out my block heater is dead, but I shouldn't need it now. Tach moves a little when I crank it but only when my oil pressure gauge hits half way and that about the time it wants to start and starts white smoking.

I have a 99 F450 bucket truck. I was up in the bucket when the engine died suddenly. It turns over but won't fire. I have no dash warning lights now either but everything else seems to be working. Lights, radio, annoying beeping sound from the key left in the ignition, etc. There are roughly 5 or 6 fuses in the panel to the lower left of the steering column that don't have power to them. Are they all supposed to have power when the ignition is on? I checked the fuse panel under the hood and all of the fuses that have 12V to them are good. There are a few small ones that don't have power to them but I don't think they do all the time.

Owning a 2001 F250 Extended cab with a 7.3 I have not had a lot of questions to ask fortunately.
My truck has spent a lot more time sitting than running lately and when I went to start it the other day it cranked fine but would not fire. Quick read on this forum and the first thing I found was how if the fuel solenoid had less than 10.8 volts when cranking it would not start.
I went down and checked the battery voltage and it was at 12.1 volts no load. I put the battery charger on for about 10 hours (time to kill) and when I pulled the charger and cranked it over, started with no problem.

I replaced my starter with a new one from car quest yesterday, it was starting to turn the engine over slow. I checked the batteries, they were fine, so went for a new starter. After installing, the new starter turned fast and fine, started the truck ok, but I noticed a fast clicking sound from under the dash. Ran it home and tried to start it up this morning, turns over fast, the clicking sound is still coming from under the dash, but the engine won't fire. Just turns over. When it's turning over the check engine (and all the other dash) lights flash.

I just replaced the glow plugs, gpr, valve cover gasket and harness. When cooled down, cranks but won't fire. Smoke DOES come out the tailpipe. If I plug it in for awhile it fires right up. What else can I do or check?

The night temperture was only about 37 degrees. But every morning my 2000 F-350 7.3 crew cab 188,000 on it would not start. The first try there would be a split second where the motor would fire, but that would be it. I had to plug the engine block heater into my generator for at least an hour before it would start. I don't see how all the glow plugs could be bad at once??

While driving my 99 F350 7.3 it died and I was lucky enough to coast home. No WTS light, no tach movement when cranking, no fuel pump, no CEL, Cranks great but no smoke or fire. New CPS & PCM still no lights or tach. Moved relays checked all fuses. WTF is wrong?

Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.

Last night I bought 2000 F250, 346k on it... Crew cab short bed 4x4 with ranch hand bumpers like I wanted .... Headed back home (Miami FL ~1100mi) and covered about 200 miles @70-75mph before i ran into few problems ....
First off, while cruising I noticed slight hesitation in the throttle, with loss of speed regardless of pedal pressure, noticeable on inclines. It would go away on downhill and get smooth response again and pick up speed. This went on for about 40 miles.
Then I noticed heater blower stop blowing hot and start blowing cold, without me changing any settings. At the same moment, I noticed temp gauge move up and I hit next exit offramp to check what's up. During right turn at the end of off ramp truck stalled. Pulled to the shoulder, and popped hood.
Noticed empty degass/overflow bottle. Carefully opened lid and water gushed up to the top. When all pressure slowly released, water pulled down and emptied the bottle. Both upper and lower radiator hoses are empty. Engine oil has no traces of water tho. There were no leaks under the truck. I then tried to fire up the truck to get me to the gas station 1/8th mile away.
No crank in Park. WTS comes on and goes off. Cranks in Neutral, RPMs come up some, oil pressure shoots up to normal running position, but won't fire. Tried a while then gave up as not to kill starter and batteries completely.
Fuel pump works 20 sec then shuts off. There is fuel in bowl. I covered 140 miles since last full fill up, so not fuel pickup issue I don't think.
Summary
Have crank
Have RPM
Have oil pressure
Have fuel
Have (had) batteries, now not so hot
It's cold out ....

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?

So on my way home today I lost all power, the engine shut of and i coasted to side of the road. Went to try and start, nothing. When key is in the crank position the gauges were jumping all over the place, also accompanied by a lot of clicking from behind the dash. Nothing happened when tried to crank. No power to windows or even emergency flashers.
So i get it towed home, and of course it turns over. But this only lasts about ten seconds, then dies. I could do that a few times and then back to no power at all. Even at times with the keys out of ignition it will still click and make a lot of noise.

I started my truck this morning and drove it quarter of a mile down the road to get some food letting it idle while in the drive through. While pulling away from the drive through window it started idling ruff . I drove it to the hotel and it ran perfectly normal until at a stop light and it started skipping again. If I put it on high idle it really starts skipping. Above 1500rpm it stops. What do you think?

My 99 E350 with 7.3 power stroke quickly lost power while on the highway today, bogged down and died. I couldn't get it restarted so had to have it towed home. I tried getting it started at home but it just pumps out white smoke out the exhaust. I got it to fire and run for a minute on a mixture of starting fluid and wd40 but wont stay running. Some background info, I checked oil and it was low but still registered at very tip of dipstick so I topped off oil level and still no start unless I give it a mixture of starting fluid and wd40. Batteries are good and cranking fast. Truck has 355,000 miles but very little blow by and prior to this had plenty of power and didn't have to use the block heater to start it thru the winter even when the temps dropped down to 12 degrees in January.
One thing I did have an issue with this past year was an intermittent cutting out while driving where the engine would instantly shut off but as soon as I tapped accelerator pedal it would start running again like nothing happened, wouldn't even last two seconds and it was running again just like shutting off the key and turning it back on and when it would do that the "Wait to start" light would come on and gauges would drop like key was off but again it all went back normal as soon as I hit a bump or tapped the accelerator pedal and it never lasted more than a second or two and never had to pull over, just tap the pedal or hit a bump and engine would kick in and run fine so not sure if that's related to whats going on now or not.
