Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Just Stop Running Like Key Turned Off
May 1, 2016
My 2001 f250 7.3 was running then just shut off like I had turned the key off, While trying to start back up, the truck turns over fine but no fire. I also have no gauges, I tested both fuse boxes and the one under the hood I have power on all big fuses, including the PCM but some of the small ones I don't, No power to the PCM diode, either side, the fuse box inside the cab, I have half power, No power to the PCM fuse is their a fusible link somewhere?
I really can't see much down there. The truck did get into a accident in Oct, which created a problem with the ignition and not sure if that could be a problem? That problem is, when I turn the vehicle off, it would stay running for a few seconds. I ignored the problem cause it didn't hinder the vehicle any.

Battery light comes on when the truck is running at less than about 1200rpm, but I see zero movement on the needle. Weird thing is i charged the batteries and tested the alternator with my multimeter and it was reading 14.1-14.2 which is nominal. Run it for about 10 min then it reads 12.3-12.8
I'm thinking a bad cell in the battery or alternator is going out. Oh and all the connections are tight, wires look good. 2001 f250 4wd 7.3 intake exhaust basic tuner gauges. Could the constant heat be a factor?

2003 CC 4x4 ... I am pretty sure I know what is going on, but I wanted to start a thread for when I confirm it. I am driving to work this AM and I hear the door ajar chime and I think to myself, uh oh...gauges all look good, there are no lights illuminated on the dash. I get to work and turn the truck off and my fan stays on. I think the ignition module is going bad. Either that, or my remote start is going on the fritz. I will update when I find out more.

While stopped, engine running, in D, the engine cut off just like I turned the key off. I sat there for about thirty minutes and on the 7th or 8th try, the engine finally started. I drove it back to camp and thinking it might be the CPS, I swapped it out. Unfortunately it must be something else because I can't get it started anymore.
ICP and IPR are fairly new, but I unplugged the ICP and tried to start it anyway. It didn't choke out (like it was a fuel issue) but I checked the fuel bowl anyway and the pressure builds fine. I got it restarted once, so it can't be a fuse but I checked them all anyway.
Oil pressure builds to 780+ when cranking. Batteries still have plenty of cranking juice and without my AE, I'm frustrated beyond belief.

No start. Changed starter solenoid. Changed starter. Now it runs although when I turn the key to the off position and remove it the engine continues. The only way to get it to shut down is remove the small wire from the positive on the battery and then turning the key to the off position or vise versa. The machine seems to be pulling power even when completely shut down. The batteries drain power with "nothing on" i d m shot? Someone stop me before I go to the dealer.

I have a 2000 F-250 7.3 L Diesel w/200,000+ miles on it.
I use the truck for snowplowing and last snowfall one of my employees broke the overdrive switch on the PRNDL shift lever. I just replaced it and as I went to start the truck I had just turned the key to run in order to let the glow plugs warm up and the truck attempted to start itself.
As it was running I could hear the starter continue to run although I never fully turned the key. I have since then replaced the ignition switch and the key lock cylinder. That didn't fix the issue, I then pulled the fuse box that is inside the cab of the truck to inspect the GEM module. Other than lots of dust there was no corrosion or any see-able issues with the module. I cleaned all connections thoroughly and even applied a little dielectric grease to the connections.
Still has the same issue, I ran a voltmeter to the trigger wire on the starter relay and it reads 10V when the key is turned to run. I believe it should not read any voltage until the key is turned to start. If I have the trigger wire on the starter relay disconnected the truck won't start, obviously. I don't believe the starter relay is bad because it does start only when the key is in the run position and it has never attempted to start without the key.

2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.

What's up power stroke fam. I have a 1999 F250 Super Duty 7.3 liter this is what happen, was leaving the job site the truck started just fine ran for about 3 city blocks stopped at a stop sign and it started to run ruff like it was out of fuel but had a half tank then poof it shut off. After towing the truck home and trying to start it I could hear a relay clicking very sporadic the service engine light came on then when off and the truck started and the exact same thing happened started running ruff and shut off. Where should I start other than taking it to the shop?

I have a 1995 f-250 7.3 liter diesel engine. Truck starts fine and runs good for a while and then it will stall. I pull over and after a couple of attempts it will start and run fine for a while. I have changed the fuel filter and put fresh fuel in but it still stalls.

I have a 99 f-250 with about 250k miles. Truck is completely stock. It recently has developed a problem where when I start it in the mornings it surges at idle, 200 rpm or so. Sometimes it tries to die and did once but started back up. When driving it continues to rev itself up and is jerky. It runs rough and sounds like it could be missing on a cylinder. At other times it runs fine just like normal. Yesterday morning it started with these symptoms so I put in a new ford CPS. It ran great for about 100 miles that afternoon. This morning it started back with the same symptoms. The SES light stayed on longer than normal when I started it, but it went off. I don't have a scanner.
I thought it might be water in the fuel because this started the day after I filled it from my transfer tank. But the water in fuel light has never came on. I put a new fuel filter on it but it made no difference. Have pulled filter three times looking for water but never found a drop. Also pulled several buckets from the bottom of my transfer tank but found no water there either. Where to look next?

Just happened today right after I bought diesel. thought it may be water in fuel but after researching wondering if it is injector, etc. It starts every time knocks real bad sometimes for a minute, but clears up to idle ok. During idle no smoke, slightest acceleration however produces white smoke harder I accelerate more it plumes and it smells like diesel in the air.
Cannot get past 15 or so mph till switching into 2nd gear then 25mph max. Had to drive 4 miles like this I can say it cleared up and drove 1/2 mile until I had to stop at a traffic light then going from idle to acceleration again ran bad rest of way home another 2 miles.
A few years ago I did have a rough idle and accel. similar and it ended up being the broke pick-up/sending unit in tank (but of course that was when you get to around 1/4 tank of fuel and didn't run bad above that much fuel in tank), plus there was almost or more than a gallon of water in tank. I have done the mod for the fuel pickup with hoses, filter canister, etc. but wondered at first today if I had gotten bad gas or water in the tank again. Not sure how that much water got in the tank to begin with but that was bout 5 or 6 years ago.
Truck has over 200k miles and Ive had it for 11 years. In the morning will check the ICP sensor by unplugging look at fuel filter bowl, etc. A question I have is: Is water heavier than diesel, would it run thru my line first? thinking diesel is heavier than gas because of oil content....

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

I have a 01 f-250 7.3 6 speed. I bought the truck a few days ago and the 4x4 wasn't working the dealer replaced the transfer case motor. I have another 01 f-250 that i have been switching parts out of to see if that makes a differences and found nothing to work. Ive switched the switch on the dash out and nothing. Ive switched the two relays under the hood and nothing. I have also checked all fuses. and the connectors on the transfer case.
So I finally popped the covers off the two relays and squeezed them with my fingers and boom transfer case locked into 4lo and then i can squeezed the other and boom back in 2h! So now I'm lost, I know the wiring from the relays to the transfer case is good and the switch is good and relays are good so I'm at a loss.. Also cruise control isn't working idk if that could be related i don't think it is but idk?

Had to change the UVC harness on my 2001 7.3. Truck fell out. Trailered it home and changed the UVC harness on the passenger side. Truck is running great, but now the OD light is flashing. Can't read transmission codes, but was wondering if something from the bad harness could have caused this? Any thoughts?

I have a 2001 F350 and over the past few nights the horn has started honking once randomly. It always only honks once but will do it several times a night (may be more that I don't hear). I'm thinking that this has something to do with the alarm maybe? I can't afford to take it to the shop at the moment (nor any moments in the foreseeable future, come to think of it) and am hoping that its something that I can fix myself?
I'm having other miscellaneous electrical type issues, but don't know it there are related at all. For example, the power locks don't work (they try to, but don't seem to have enough power), the overhead console that digitally displays the outside temp/mpg/etc. stopped working suddenly and the lighter/power plug outlet stopped working, but I was able to fix this by replacing the fuse.

A bit about my truck : 2001 F250 CC SB 4x4 175k miles
Wicked wheel, 6637 filter, DP tuner, Summit 5" exhaust, pressure regulator somewhere in the boost circuit to fool the computer a bit....
Every few times I drive the truck it will stumble and maybe even stall. The issue feels something like a CPS problem, although I've swapped out a few CPS to see if I by chance had a bad one in the engine as well as a bad one in the glove box. No changes. I was driving home from work one afternoon and it was running particularly bad. I stopped off at a local garage (who doesn't work on diesels and was reluctant to plug in....but did because he's a nice guy).
He plugged in with his snap-on tool and came up with P0603 and P1211. The P0603 seems to be nearly inevitable with a tuner. Check P1211 sounds like it could be an issue with a number of things, but I tried to attack the free and cheap issues first. I dropped my tank and had a look inside. I was hoping to find a squirrel wrapped around the sending unit, but there was a disappointingly small amount of crud. I cleaned it up and put it back in, then changed my fuel filter. No improvements.
So I decided to get with the program and buy AutoEnginuity. Got it. Even did some reading in class and did the initial homework assignment on page 2 or 3. Seems like the best thing to do it hook up, set up some parameters to monitor, and drive around recording until the problem happens. But.........what parameters do I want to monitor? I don't want to overtax the OBDII bus with too many requests such that my data looks like crap.
A few other things............ In the last year I swapped out the valve-cover gaskets & harnesses with an all-in-one molded setup. About a month back I replaced the exhaust back pressure sensor and tube.

The fan clutch will come in and out rapidly when NOT in OD and pulling hills with the fifth-wheel attached. Replaced with a new aftermarket fan, then a new OE one. Then had the radiator pulled and all the bugs, etc. blown out. The condition has not changed at all. The original fan clutch was pretty sloppy. There are no codes, the trans fluid is nicely red, the engine does not overheat or even change temp when pulling hills. No check engine light ever. The truck is a 2001 F250 4 X 4 automatic extra cab with 7.3 engine without any modifications and runs perfect except for this. There are about 95k miles on odo. When we use overdrive on the flats, there is no issue.

01 f250. Just bought from my brother. 140000 miles. Immaculate. Truck will die for no reason. Running down the highway, or sitting at a red light. Fires back up. Sometimes have to crank a few times. He has had at a mechanic and everything checks out good. Since birth its only had royal purple that he has changed every 5000 miles as well as all filters. Where do I start?

2001 f250 7.3 with 210,000 miles. Was running rough when cold and glow plugs were bad so I bought new glow plugs and had injectors rebuilt with 100% over stock nozzles. When I changed them I made sure I turned the motor with glow plugs out and pulled the drain plug in the head. Wanted to start it just to get the oil out before I let it sit for a few days til I got the tuner. It started fine and I let it run while I ran in the house and when I came back out about 1 min later it was off. Didn't want to start again. Just left it til I got the tuner on and It still doesn't want to start. What I should check? Turns over good and has good batteries. Also it's a hydra chip tuner with beans tunes. Darren weeks rebuilt the injectors.

So I have a 2001 f250 7.3l and on my way to work yesterday while driving down a hill I switched my ts 6 switch to 140 and it immediately stalled, so I pulled over and restarted the truck and it started up fine and I drove the rest of the way to work, I go to start it after work and it won't start, it just cranks and cranks and cranks, occasionally it'll fire and I got it to start and was able to rev it for about 30 seconds but then it died, disconnect the 6 position switch from the idm and tried but still nothing.
So today I replaced the ipr valve, got everything back together still won't start maybe a little worse now, I know it's getting fuel cause there's pressure in the bowl when I try to take it off, there's a new icp valve, cps, new fuel filter and new sending unit, the hpop is topped off. Also I noticed when I went to change the ipr the wires on the plug were bare and touching so I addressed that, I don't know what else it could be?
