Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 Hard To Start / Cranks For A While / Sputters And Dies
Dec 21, 2015
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 have an issue with my 2001 f350 7.3 PSD. Intermittently it will not start. It will crank really quick, but will not even try to start. I think it is not getting fuel. There are no CEL codes and I have a WTS light and the tach is moving while cranking. I hear a clicking/buzzing sound coming from under te center opf the dash. When I hear that sound it will not start. checked fuses and relays and it started before. not sure if removing the fue made whatever reset. this has happened a couple times. Now it will not reset. When I remove the number #24 fuse under the hood, the clicking stops. when i crank it, but still doesn't start. When it starts in runs perfect. Drained the batteries trying to trouble shoot, but have them charger now.

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.

I have a 2001 F-350 7.3L Powerstroke. 48,000 miles. I've been having trouble with cold starts. So far it has always started but is taking a lot of cranking, but it hasn't gotten too cold yet so I'm worried about when it does. I ohmed out the the glow plugs and am getting close to 0 resistance. The GPR has 12.5 volts on the hot side and when the relay is closed 10.5 on the other side. Is that difference in voltage in the GPR enough to screw up the Glow Plugs heating up? If I plug it in at night it starts right up. I'm worried about when I am at work for 16 hours and don't have a place to plug it in this winter. BTW this is my first winter with the truck.

My '99 f350 lost a lot of power the other day, turned out the the injector harness got unplugged. So I swapped those out for oem ones, ohm tested the uvch and injector harness, put a brand new GPR, and still nothing. Cranks over but won't start, what else could it be?

My truck will set an idle fine but when I hit the throttle it will die.

It's a 99 f350 7.3 diesel powerstroke. About 180k miles I think.
It cranks fine. I just changed the glow plugs(all were dead) but when you try and start from cold, it takes about 7-10 seconds to fire. The oil res is full, tried disconnecting the EOP sensor, still fires up and takes just as long. There is one near the oil filter, and that seems to not be it either.
Doesn't smoke, no oil leaks that I know of. Not sure what else to check before sending it to another shop to get put on a diagnostics machine. I read about the IPR, but it has no problems when running. Only problem is a very long time to start. Also changed the fuel filter.

I have a 2003 f250 with the 5.4 in it. When I bought the truck the odometer and fuel gauge weren't working. So I tried disconnecting the battery and when I hooked it back up the odometer started working again and the fuel gauge went from below empty up to full then just dropped back down to below empty and won't move at all. I haven't tried disconnecting the battery again. And I know more than likely I will have to replace sending unit but trying not to if I don't have to.

I drive a new to me 2005 F350, he has a 2001 F350. While we were talking he said he didn't think his pickup had the power it should have. He pulls a 5th wheel camper that weighs around 8000 pounds fully loaded. He said it takes a couple of miles to get to 55 mph, and it is hard to hold the speed. It doesn't have the power it did when he first got it last year. He was told that a diesel is slow getting started. He rode with me in mine, when I dropped it about half throttle to pass a slow car he said he could tell mine had way more power.
His check engine light is not on, it starts good both when hot and when cold. It runs smooth, no miss as far as I can tell listening to it. What are some common issues that could cause this? He did just change the oil and fuel filters, not sure about the air filter. He said the power loss came before he serviced the engine, and did not improve after the fuel filter change. Where to start? He was also told to check the filter inside of his fuel tank, so he is getting ready to drop his tank.

I have 2001 7.3 f250 ... I just got it about 2 months ago I drove it for maybe 2 week and it ran good the other morning I went out to start it and would not start and the way I was parked my low fuel light was on so I put 5 gallons of fuel in finally got it started sum how drove it for maybe 2 hrs parked it and wen we got back in to go it was done for hasn't started since its been down for a bout 2 weeks now I've replaced hpop, icp, pcm, fuel filter,checked idm for corrosion it all looks well, gpr,checked uvch on driver side looked good and changed cps what else do I have to go from ? No matter what it won't start good batteries cranks good but no start ...

2003 F350 7.3L 164k miles. Got towed in with hard to start cold complaint.
Hooked it up to the Snap On Verus Pro scan tool and we get up to 3000 psi on the ICP cranking, IPR value seems within spec, we have rpms over 100 on tool, pulse width within spec, computer voltage above 10v while cranking, verified output of glow plug module (California) and glow plugs get voltage for approx 50 seconds @ 80 degrees farenheit, glow plugs all read 0 ohms resistance.
injectors do NOT sound the same during buzz test.
Vehicle takes EXCESSIVE cranking cold to eventually get it started. LOTS of cranking. Just had to replace starter and a battery because driver burned em out. It feels like the vehicle shakes when it gets running. Black smoke when revving cold. Sometimes white smoke while cranking.
Once the engine has been warmed up, it starts perfectly every time.
I have spent two days in the engine bay looking for chaffed wires and doing diag and my current diagnosis is bad injectors. I feel there COULD also be high pressure oil leak, or a mechanical issue such as low compression. No compression guage yet for this truck. We have the ICP and IPR fittings to do a shop air test. Recently did a 6.0L and went thru everything and eventually diagnosed it as bad HPOP. LOW ICP pressure.
I noticed two of the cylinders were at maybe 8% Perdel on the data. Seems too high. Also, it "passed" the KOER self test and "passed" the injector buzz test with no codes after, but the audible sound of injectors didn't "seem" right to me, but I am new to these engines.

This is an issue I started chasing after having all the injectors replaced on my aunt's F-350. We had them replaced due to hard/no start on cold (dealership told her they needed to be changed). Unfortunately, I did not get the buzz test results before changing the injectors.
So far that has been replaced:
Injectors
ICP (was leaking)
IPR
both UVCH
IDM (twice)
The issue we are having right now is that only 2 injectors (#6, #7) buzz properly. Initially when we changed the injectors, it did start but didn't seem to run quite right. We did the buzz test and at that time and injectors 1,3,5,6,7 would buzz strong but the rest were weak. After some forum lurking, we suspected that the IDM was faulty. We purchased a refurbished one and after we changed it, only injectors 6,7 would buzz strong. Thinking a faulty IDM was sent it back for a replacement. While waiting, we decided to put the old one back in figuring it would go back as it was before but only 6,7 would buzz strong. We receive the second IDM and same thing, only 6,7 buzz strong. We did a continuity test from the IDM connector and they all get 2.7 ohms (it was an older multimeter so not sure if being .1 under the 2.8-3.6 range is bad).
What I did next is use the uvch external pigtail to test the injectors. I plugged the extra pig tail into the uvch and then the ends of the wires into the plug of the upper harness. Afterwards, I would swap a different injector wire (on the pigtail) to the #6 injector wire (on the upper harness). Whatever injector that would go to #6 would fire correctly. So I know that the injectors themselves are fine. I am suspecting the wiring harnesses (upper/lower) but the continuity test would say otherwise. We also do not get any fault codes except for the EBP occasionally (waiting for a new one). I am lost on what to test or look at next.

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 been having problems with my truck for about 6 months now. It start in Sept when my fuel pump went. I got a new pump and went to change it just to have the back clip break off. I fixed the line after getting 2nd degree burns from the boiling water I had to use to expand the line and installed the new fuel pump. Didn't fix anything.
At this point is was dropping below freezing every night ( I live in Canada in the mountains) so I thought it might be my plug relay again... changed that. After that my started has always missed so I figured I would change it out and sure enough the power bolt on the starter was broken. Changed it.
Then it started smoking and I read up on the quarter trick so I figured why not try that. I checked everything and they all checked fine but I am a glutton for punishment and figured I would do that valve cover gasket. So opened it up to find one of my glow plug wires on my harness was burnt up. I have a spare truck for parts so I grabbed the wire and replaced it. Still no change.
Today it was spitting out the usually raw diesel that I have gotten use to but when I was opening the gate to get a manlift for work I smelt oil just to find my turbo coved and the V had a small pool of oil happening there. I added 4L of oil and tightened up my valve cover back bolt on the passenger side... it may have fixed the leak but didn't have time to check.
I backed up to the manlift and it lagged a bit so I gave it a pump of the peddle and it died. Now it won't start. Charged batteries and tried after it cooled down but still no go.
In short my truck has been smoking for about 4 months now. It shutters at low RPM and stalls at the bottom of hills if I gear down on the hill (we have really steep hills around here). I have changed my oil three times in the last 6 months but it keeps coming out black (which it always has). No water in fuel or oil. Once and awhile it had problems starting when it was warm but after bellowing out massive amounts of smoke it would start. The truck turns over but wont start. There is no power where it died so I have to come home and charge the batteries every time they get low but even after it cooled down it still wouldn't start.

My 2001 7.3 in a f350 automatic has this problem. I tried to start in am, no wait to start light comes on, but the od/off on auto transmission handle is blinking on and off. Turn key off and back on, no blinking, instrument cluster lights up as normal but no wait to start light, engine turns over as normal but no start or attempt to start, engine has about 56000. replaced glow plug relay, still nothing.

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.

My 2001 7.3 was smoking excessively and I rebuilt the turbo and the center cartridge was at fault for that. I'm still having some of the problems I was having before with a lot of smoke at cold start (I have to hold the accelerator down while I start it and it takes about 10 seconds to start) even when I hold it I have to keep it held for about 5-10 seconds before the RPMs get to where they should be. And it smokes like crazy.
Then after about 3 minutes warming up, or 30 seconds of me holding it at 3500 rpm, the idle smooths out and it only smokes a little. Then once I start driving it doesn't smoke a lot unless I go hammer down then it puffs some white smoke. I took the oil cap off and it isn't huge amounts of blow by cap just rattles off. Can ford buzz test and see if I only have 1 or 2 bad injectors? Could this be anything other than injectors? It has a ts6 on it with 24xxxx miles with factory injectors.

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?

Here's the situation - 1999 F350 with the 7.3 PSD, crew cab, auto, 4X4.
The truck runs fine in good weather, but if it's raining or snowing, it will suddenly die - and by that I mean lose all power as though you turned off the key. There's no warning. It lasts for a period of time, and then the truck will restart - most of the time.
It's seems like it should be a pretty simple/obvious electrical problem, but I've had the truck in to two of the best diesel shops in town, and neither has been able to locate the problem, in spite of countless hours and some pretty big bills being racked up.

I finally got my 02 F350 running again after replacing the Fried PCM, but during some additional shop prep work, I discovered that the engine dies when you use the horn button, it will start right up afterwards so no permanent damage, but, Where to start? I have Forscan and a cable so I can get into the PCM but I need to know where to look or what PIDS I should be watching during troubleshooting.

I have a 2001 F350 Dually 7.3 w/260K miles. Hard starting, it has to be plugged in all the time. Occasionally/most of the time, blows white smoke at 50 to 60 mph or at high rpm. Replaced TPS and now runs totally different on starting, still hard to start but better throttle response on starting. Once started, I have to pedal it to keep it running, which seems to have little response as it would as if it was a direct throttle linkage attached to a carburetor...follow me? After a while, it will idle by itself. However, it still has flat spots when out of idle and at high rpm. Has gotten to the point that I can't trust to drive it.
