Ford 7.3L Power Stroke (1999-2003) :: Intermittent Starting / Spin Like A Top But Not Fire
Mar 26, 2015
2002 7.3 PS TD.
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.

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.

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

My 02 f250 w/ 7.3 won't start. Cranks and nothing. No smoke or anything. For the last year It has had a intermittent starting problem, where I would drive it for 15-20 mins. If I shut it off like I would if I was at the fuel pump and then restart it, it wouldn't. I'd have to wait 30 minutes with a hood open and then it may start. Other times I would have to wait hours.
I tried replacing the crank position sensor, the fuel pump and filter.I did all this in the Last 300 mile . There's No change. After a week or two of sitting it won't start. What can I check and what can I try.
To add more info. Since I am not the original owner I pulled the computer that is located behind the ebrake to see if someone else had installed a chip, as I've heard that if that chip goes bad then the truck won't start. I disconnected that battery and pulled it. Negative on any chip. Put it all back together and tried again. No start. I borrowed a code reader tonight and pulled a P1280 code. I'm back to square one.

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

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 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.

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 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 ....

I am working on a 1995 S10 Blazer. it has a 4.3l vortex. The vehicle runs good. The problem is when it is shut off at end of day. Then the next morning it will not start. Then at a different time in the same morning it will start and run all day. I have fiddled with it when it will not start. It acts like it wants to fire but will not start. If I am persistent with it and crank and pump the hell out of it eventually it will start. I have checked the fuel pressure when it will not start and it is good. There is also spark. I don't know what to check next. I has been cold when it does this. What to look at?

My 7.3 power steering is acting up. Feels like I am up against a rock. At slow speeds like parking lot maneuvering I struggle to turn wheel. Then all of a sudden I'll get power steering back and wheel will rapidly turn. Freaky.
Brake pressure is fine. They shutter pretty bad even with the new rotors I just put on but they have good pressure. But the steering is intermittent or no power steer.
I saw online to run engine at 2000 rpm and try steering but no change. Still no power steer. There is fluid in reservoir. There is fluid seeping up steering column from steering box. No clue if this is related or unrelated.
How to troubleshoot further. I hate throwing parts at problems before truly diagnosing. Also have pretty aggressive lurching during turns in four wheel drive. It's present on dirt road but worse on pavement. Don't know if this is related or not.

I have a 2000 Excursion. This weekend, I noticed some intermittent failure of the power steering where it seemed like the pump was not engaging and then would all of the sudden. Deciding to try to head off a failure, I got a reman unit from Oreilly and installed it this morning. It was fine when I tested, had good brakes and went locked to lock quietly without fuss. Let the house and within a mile, I lost steering and brake assist. I stopped and turned around, but what I am noticing is that at idle, I have no power steering, but when the RPM's are up, I do.

Intermittent loss of power (could be describe momentarily stuttering) with momentary illumination of the check engine soon light. Its only happened a couple of times. Maybe about a year ago (I changed the fuel filter after it occurred). It occurred again about a month ago and then again yesterday. About a month ago I had a friend with a scanner look at the codes and he said there was only one and it was for low fuel pressure. Its been maybe 5k since I changed the fuel filter.
The truck is driven intermittently, maybe 5k or 6k a year, and usually parked with a full tank of fuel. What areas I should look at to correct this? I got my stock 2001 F350 4x4 manual transmission in 2004 with about 157k miles. Today I've got about 228k miles.
