Ford 7.3L Power Stroke (1999-2003) :: F350 Will Crank And Run But Shuts Off When Gets To 150 Or 180 Degrees
Jul 16, 2015
I have a 99 f350 Ford 7.3 service truck. It will crank and run but when it gets to 150 or 180 degrees it shuts off and will not crank back until it cools off. I have change the ECM I have change the IDM still same thing it runs till gets hot and then it cuts off. I have changed IPR valve IPC sensor .check the high pressure oil pressure it is around 800 900 at an idle it is around that pressure but when first starts up it is higher once it starts and runs it idles around that pressure 800 900 psi....
I have hooked up my scanner and it shows around 150 degrees oil temperature it shuts off . The high pressure oil stays the same as it was when you first crank it the low pressure crankcase oil is 60 psi ... Once the oil temperature reaches around 150 ~160 degrees the engine will shut off . Once you let it sit overnight or for several hours it might crank up ....

Just purchased a 2003 F-350 Super Duty Lariat Crew Cab w/ 6.0L Powerstroke Diesel w/ 192,000 miles. This truck will be used exclusively for pulling my 36', 8,000lbs travel trailer. I have a 2011 F-150 Ecoboost as my daily driver. The 2003 was purchased from a used dealer in Texas and is in immaculate condition and was definitely not a work truck. It was a 55 degree day and the truck was inside their building when I picked it up. No starting issues then and drove it the 3 hour 70-75mph trip home, with 2 stops on the way (wife was along) with no issues. Started quick and ran like a champ. The next morning it was 32 degrees outside and it would not start. I cycled the key on & off several times prior to starting and still no start. Plugged the heater in and 1 hour later it fired up. I have noticed since that if the outdoor temperature is below 55 degrees, it will not start without being plugged in. When plugged in, it starts easy, no smoke, purrs like a tiger at idle and runs great. I Have started on a mental list of things to check.....here goes:
1. The dealer stated he just changed the oil & filter. Can't rely on this 100 percent so I plan to put new 15W40 oil and filter in. Oklahoma summers are pretty warm.
2. Check the FICM for 48 voltage output.
3. The glow plug indicator on the dash is working. The colder it is outside, the longer it stays on. If the indicator is working, is this an indicator that the glow plug relay is working? Anyway....plan to check this relay.
4. Pull one or two glow plugs, ones easy to get to, to verify their function.
5. Check both batteries....I assume they will have to be disconnected from one another before doing this.
I have been working on gasoline engines for 40 years and no stranger to busted knuckles & dirty fingernails.....just new to diesel engines. I am impressed however with their construction and method of operating.

My 2001 F350 7.3 dually diesel Automatic has been a pretty good truck but recently it has been dying. Engine just randomly shuts off without warning while Driving. Check engine light comes on sometimes. Some of the time it will restart if I cycle the key. Once its running again I can rev the engine up without a sputter but after a few hundred yards down the road it will die again. I noticed driving on the highway when it does it my truck will buck first, then...
If I leave it in drive with the key in the run position when it dies and I'm coasting down the highway the Tach starts jumping around like its trying to restart itself, all on its own. I don't have a scanner.
The last time it died I coasted into my driveway and it wouldn't restart, went back out there 30 minutes later and it fired right up. Its only 40 degrees here if that matters, not hot by any means.

New to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.

I've replaced the alternator and starter recently and both batteries and the truck ran fine befor that. But it sat for roughly 2 months and now it seems as if its not getting fuel. Will start with a shot of ether but will die as soon at it burns it off

I have a 2000 F350 7.3 ... A couple weeks ago I noticed that it was taking longer to start then it should be. Now I have to cycle the key switch 3 or 4 time to get it to start. There is a clicking coming from the relay block under the radio. Sometimes the truck will start sometimes it has to be rolled off. I have recently replace the starter and alternator. I have had the batteries tested and they are good. I replaced the two small relays in the block under the radio, one is for the fuel pump and the other I understand is for the door locks? I also read on here the large blue one is for the turn signal so I have not changed that one. After all this I still have the same problems.

I just started having an issue on my 01 7.3 f350 with 203k miles, it will crank much longer then normal to start. If you shut it off then try to restart right away it starts normal, if you wait 10 minutes long crank again. if you shut it off and turn key back on but don't start it you can wait an hour then start right away. IDM bad? Vacation in 2 weeks and I would like to get this fixed first.

I have looked through a ton of threads to see if I can find one similar to my problem but have not. I have stock setup but had a dealer installed anti-theft device. The first time it would not crank, it was like the the anti-theft plug was missing so I checked out the key, tried the spare and finally removed it all together. I checked all the fuses and swapped the Starter relay for another of the same part number.
I later sifted it into neutral assuming it was the P/N Switch and it started. This continued intermittent for several days but then Neutral wouldn't work. I got under the truck and pushed on the actuator rod for the transmission and it started again for a few days. If finally failed again and I had time to buy a replacement switch.
Once installed I verified I had back up lights in reverse but still no crank. I have since pulled off the starter and had it verified as good. Is there more to setting/adjusting the neutral switch or is there something I am missing before I tow it in?

I recently (in the last few months) have noticed my truck (1999 F350 duallie) seeming to be running very rich … I pull a 32' trailer with it and noticed on the art few trips the front and right side of the trailer covered with diesel fuel spots when I got home …. It also smells very rich when idling…. The last couple times I started it in the mornings it seems to crank a very long time before it starts …it still runs but its got issues evidently … it has these 3 codes :
P1280
P0475
P1670
The 1670 will clear , but the other 2 I can't clear, they are right back every time you turn the key on …

What EOT temp should the fan clutch kick on at? I've never heard it kick on until a recent trip. It seems to go on about 228 degrees EOT and keeps the EOT below about 232 degrees.
At slow speeds I've found that the trans will heat up to this temp too. I assume because the radiator cooler is at that temp an there's not enough air flow for the air cooler to cool it down much?

I have long been having troubles with white smoke at startup, even when its 90 degrees out. Long story short I've got new glowplugs, GPR, UVCHs, valve cover gaskets, injectors, turbo, valve seals, valve springs, and HPOP all within the last year. Most of those parts were needed, some maybe not so much. After installing injectors things started getting worse, whether they're related or not I'm not sure yet. I pulled passenger side valve cover off again in an attempt to figure something out and heard this coming out of the intake spider.
[URL].....
The strange thing is it goes away when it warms up. I should also note the reason I started with the passenger side is because I did a compression test and this side had the lowest readings, with #5 being 270 psi. I disconnected each injector one at a time on the passenger side to see if it made a difference while running but didn't really notice a difference. Am I looking at a motor rebuild, or at the very least a head removal?

03' F350 Crew Cab DRW FX4 Lariat 6.0
180k miles
Has EGR Delete
Blue Spring Kit and recent Fuel Filter Kit
Last Friday I got the truck back from a local mechanic that had replaced the water pump. Took it out to put fuel in it last night. About a mile from the house it felt like it bucked then died. While still rolling I stuck it in Neutral and started it back up. Got fuel and back home, no problem. Total trip around 4 miles.
This morning I get about a mile from home (other direction) and it does the same, engine quits and it rolls to a stop. Except now it won't crank. Has electric power, just won't turn over. Both batteries are pretty new Napa big CCA ( I believe 800 ).
I walk back home and get my '04 F250 6.0 (180k also) and drive back to the stricken 350. Thinking a battery may have crashed a cell I remove the ground from one battery and jump it off with the 250. No difference. Reconnected battery #1 and Disconnected battery #2 ... Same thing, no crank.
I didn't really think it was a battery issue since it started fine, but if one of them had crashed a cell it could have shorted. No dice.
Now I'm thinking it may be the fuel pump. Would not having line pressure keep it from at least cranking? IE like a safety feature so the injectors don't try and run dry?

Just got my truck back (450) from rebuild on tranny. Hooked up my new obd link mx , and was out running the truck for a while. Started running it pretty hard to see what the gauges would do. Noticed the engine coolant was getting up pretty high, usually around 240-250, and then hit 270!!! My temp gauge on the truck wasn't budging , just stayed between hot and cold. Is this normal?? Seemed pretty hot to me but if i just took it easy on the throttle it would average around 230. If i stop and idle it quickly goes down to 206. Look at oil temp and tranny temp also engine coolant temp is bottom middle.

2003 6.0 will fire within 2 seconds when cold, literally a "bump the key" and she fires up scenario. Recently and only when the engine is hot I'm getting extended crank times and sometimes it takes several attempts for the truck to start. I replaced the HPOP with an upgraded pump after the factory HPOP went out at 311,000 miles. I know this sounds like a standpipe leak scenario but it doesn't act up all the time, sometimes it fires right up even when its hot. my thinking is a leak is a leak and only gets worse.
My IPR is reading in the 26% range, FICM is steady in the 47.5 to 48 volt range and at idle 585 to 600 psi on the ICP with a good FICM sync. I'm going to to use my scan gauge and see if I can catch an extended crank scenario to see if the ICP is reaching 500 psi but is there somewhere else I should be looking? FICM relays possibly? I've noticed when i turn the key on I'll hear the fuel pump,vacuum pump but the clicking sound is very brief or nonexistent (not sure what the clicking noise is from I assumed glow plugs but its absence is noticed)...

I was driving home and my dash shut off and motor then came back on. Thought to my self hmm not good. Then she did it again. Then thought well that will be hard to find if it only does it two times. I will fix it when it happens more would be easier to find. Then off and coasting down the road. Now on the side of the road. But from what I can till now it seems like my pcm is not getting power. I was able to crank and get it fired then shuts down and will crank but keeps kicking the starter out.
Now it will not crank lift pump not running and injectors not doing there pretty firing sound. I don't have anything to check fuses with me just going to tow it to my shop and look at it tomorrow. But the fuse panel is not label at all so is there print out I can get of that? I'm a diesel tech so I'm not really to worried. Can't pull codes or Talk with my sct programmer so makes me think. ecm no power or fried,

Having issues for a couple days now. Starting with the last two weeks while driving, the water in fuel, wait to start, and check engine lights would flash on. It would resume with more fuel as if nothing happened. Twice on separate days there was enough water that it shut it down in the middle of driving and it would have to be parked then restarted. One morning went out to start the truck, was inside for about 10 minutes and heard the truck shut off. Went out to see if it would restart and there was no wait to start light. Fuses have been checked and none are blown. Been shutting off like this for a couple days while trying to warm up, so it hasn't been driven because it hasn't ran long enough. Yes it's plugged in because of the cold.

Headed to town with the kids and my truck shuts off going down highway. I pull over and start it back up and make it to 30mph and shuts off again. This time it will not start. I have 1/4 tank of fuel, I first thought it maybe the issue inside the tank causing it to shut off. I get some diesel pour it in and it fires up for about 15 secs and shuts off. I pull the fuel filter, making sure o have fuel in the bowl. Start it up and it runs for about 10 sec. I then swap out the CPS. Same thing, runs about 20 and cuts off. I then call AAA because I am tired and ready to go home. I have it towed to my buddy's shop. He has not looked at it yet.

This started about 6 weeks ago. While sitting at a stop light the motor cut out. After some research I replaced the cps. Truck ran fine for about 3 weeks, then shut down again while pulling into the driveway of a store. Replaced the cps again (this time with a ford one). Ran fine for another 3 weeks, then shut down again on the freeway. No CEL on any occasion.
It's just like someone turned the key off. No rough idling at all. No smoke during starting or driving. When it shuts down, it will not start again for 20-30 minutes, no matter how many time you crank it. It will just turn over, no sputter. When it fires up again there is no air in the lines either, it runs like nothing happened.
I'm now thinking it might be a ipr issue...is there a way I can check myself or does it need to go to the mechanic? Or is it something completely different? This is my mother in laws daily driver, 178k. She does not drive on the freeway, 80% of the mileage is city driving. What could be going on?

A month ago I got into my truck in the morning and when I turned the key to Run everything lit up like normal and after the glow plugs warmed up, I turned the key and there was about a two second delay between me turning the key and the engine cranking over.
The next couple times I tried starting the truck that same morning I had to try to start it a couple times because it wouldn't try to crank over the first couple times but it would always eventually start.
It's been continuing to give me problems but never stopped running once it was started and then this morning I tried starting it for 45 minutes with no luck.
What I have tried so far is:
Resetting batteries
Jumping the truck
Checked to see if the starter is getting power. ( I put wire testers on it while someone else started and I didn't get a good reading even when it did start. New starter was put in 9 months ago.)
I also made sure wire going to starter wasn't corroded
Battery terminals are also not corroded
Checked fuses
Tried starting truck with fan clutch disconnected
Cussing at it
Tapping starter with a hammer while trying to start it
Also, everything sounds perfectly normal when I turn the key, it just doesn't even try to turn over.

2004 f350 after i shut the truck off something was buzzing. So I popped the hood and found its the injector harness or injectors.Is this normal or something I need to look into?

Iam looking at a 2000 7.3 Powerstroke that has some problems first it is hard to start cranks like it has a dead cyl. Second after starting it has no power not even enough to move. At first it would only run if held wide open but once it warmed up it would idle and rev and move but barely still had a miss. The weird thing is it did not smoke blue-black or white also no strong smell of diesel and no smell of oil at all. The truck has 230ish miles and there are no maintenance records.air filter was new.
