Ford 7.3L Power Stroke (1999-2003) :: Power Stroke Malfunction - In Reverse / With Lights On Engine Shut Off
Aug 9, 2015
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.

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'm wiring a backup camera and I need to energize a wire with +12v source that turns on when the truck is placed into reverse.
If I can connect the wire to 12v which automatically energizes when the truck is shifted into reverse, the backup camera will turn on automatically.
Surely I could pull the signal from the reverse lights, but I'd like to find something in the fuse panel because that is where the wire terminates and I'd rather not extend it all the way to the reverse lights on the back of the truck.
Where's a +12v source in the fuse box area under dash that energizes when the truck is put into reverse?

I have noticed that I have to hold my gear selector towards park to get the reverse lights to come on. Also some times I have to hold it towards park to get it to start. I changed my tranny in Dec 2009 and occasionally it would do this while starting, just noticed the reverse lights about a week ago. Tried moving the cable where it attaches to the tranny a couple of serrations each direction. No luck. Is there another place I can make an adjustment?

I have a 2000 7.3 f450 having some electrical issues. When you turn the key on sometimes the dash will start ticking and left side light flashing...engine will turn over but it won't start. The ticking is coming from under the hood relay 32 (you can hear and feel it clicking). Book says its injector driver module power relay. A lot of the times it will start fine other times it will be running and just die (prob because of this issue) happened once when I was driving.
What to check here already replaced the relay still have the problem.

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.

I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

I have a 99 F 250 7.3. It runs fine at idle even for a long time. When I drive around the block a couple of times it will start chugging and lose power and shut off. I have been mixing fryer oil with the diesel. I changed the fuel filter, oil change, crank sensor and fuel pump. I added 15 gallons of diesel and diesel treatment. Pulled fuel filter and bowel is full I'm not sure where to look next.

I have a 2002 f250 CC 4wd 7.3 and I have no power to my reverse light sockets. I am stumped, all my fuses are good, I don't think there's a relay so i haven't checked that. My neutral safety switch is good, I'm getting power to both the blue/pink and black/pink wire. What it could be, at first it was constantly blowing fuse 27 every time I put it in reverse but then it stopped blowing it obviously because they won't come on.

Lately I had a couple glitches seemingly unrelated with this electrical system. Something just failed. I have two new motor craft batteries cleaned all wires/ clamps. The alternator has been tested good. The other morning I started my truck and smelt a wire burning up before I took off. Battery positive to glow plug relay was hot. The solenoid was junk so I replaced it. Still not the problem. With the battery positive hooked to the solenoid, truck will not shut off. It will shut off by key if the wire is unhooked. I do know this. When hooked up, the battery positive is feeding voltage (.4v) through a new solenoid to the PCM, thus keeping the pcm life when the key goes off. Bad pcm? With the battery positive hooked up to the glow plug solenoid. There is such a large draw that the charging system cannot keep up. Wich out me on The side of the interstate at 1 am as I watched my lights grow dimmer til truck stalled. U hooked the battery positive from solenoid got a jump and been fine since....however, there's a major problem lying there right?

My coolant bottle, as well as my entire engine compartment, is full of oil. The truck won't run. It will make ICP when I first crank it but then it goes away. I have the orings and gaskets to do the oil cooler, it is there any chance there's something else that caused this? Anyway to diagnose the oil cooler before I disassemble?

Ok let's start I have a 1999 f350 7.3 4x4 Work Model that I'm have some odd transmission problems. I drove it 20 mins to do a 2hr job no problems finished that got in took off I few seconds down the road it was like the tranny just dropped out no sound just reved no gears at all. So I shut it down tried to start again would not start in park without pulling up on the lever which had experienced here and there for a good while. So got it started went in gear took off same thing went popped out no gears. I started it again this time used reverse same thing as drive so got it where I knew I could leave it but now it would not start in park anymore at all. Next day picked up a neutral saftey switch changed it now it starts in park every time but still starts going looses the gear then have no gears shut it down sometimes had to wait a few then again same issue.

I was pulling the I-40 ascent to Asheville today while empty, got to the top and started down the other side got to semi flat road and the tach suddenly went up about 600 rpm's. Transmission temp about 180*F. I let off, then resumed and everything was fine. About a mile later it happened again. This time the tranny lost 3rd and OD, still had 1st, 2nd, and Reverse. So, we limped into a service station. Temps hovered in the 170-180 range. At this point there are no codes, no lights, O/D is not flashing.
I shut the truck down to check fluid level and current condition. Everything was fine last night. Fluid level is still good and fluid is still red and clean. I changed fluid about 2k ago and the fluid coming out looked almost as good as the fluid going in.
Got back in the truck started it up, checked for codes and got a P0705, put the truck in gear to get to a diesel shop down the road and everything was fine, shifted completely normally through all the gears. This lasted until about 1 mile from home and then the same thing happened all over again. Fluid still looks clean, not burned, still no CEL, no flashing O/D, but only have 1st, 2nd, and Reverse.

My truck occasionally gets a hot no start issue and it's been happening more frequently. Mostly it happens if I drive it up to operating temp turn it off for a short time, then try to start up again. Usually, if I wait 15min to an hour it will start up. It has died on me while driving too, then I have to wait and periodically try it. I've noticed in this situation that if my glow plugs turn on for only a short time, it won't start. But once the motor has cooled enough that the glow plugs stay on for the longer duration, then it will start right up.
I've replaced the CPS, rebuilt the IPR, did the ICP unplug test, rebuilt the injectors, replaced the fuel filter.
HPOP oil level is good, changed the oil maybe 500mi ago. When it's a no start, the low oil pressure gauge does start to read after some cranking, also the tach does read. It throws no DTCs. My reader isn't able to monitor live sensor data.
There is some oil in the valley, but I can't find the source. I think it's probably the turbo pedestal. What else should I check?

Ok after rebuilding trans and being down a couple of weeks, I went on my 1st run since completing. Noticed when I started truck this morning it didn't turn over as fast as it was. 30 miles down the road Airbag Light comes on, and then volt meter dropped to 8 volts. Got stopped with truck still idling checked everything I had the tools to do so for. Decided to get back to my shop where I had tools, and 5 more miles and 55 mph truck just shuts off. Lost all power, truck would only click. Put my booster box on battery and gauges went back to normal but still wouldn't turn over but maybe once? Only place within a mile of my location was Walmart. Bought 2 new group 65 batteries, installed them and Shazam cranked right up no more problems. Short of the story bad batteries that checked Good with a load tester don't mean squat!

Truck is an early 1999 F250 Super Duty ext cab long bed, ZF6 swap. 164k miles on the dash, has the newer injectors and hpop from what I was told. It does have a 6 position switch, I typically keep it at the daily 70 horse gain tune. I do not beat the truck often. I don't tow often either.
Truck always took a few seconds longer to start than other 7.3s I have seen. So two days in row, after 8 hours of sitting in the sun, my truck did not wanna start right. Took about 5 minutes of cranking both days to get it to start. Then today on my way to work in the morning I started truck let it idle, everything seemed fine, Started driving and the engine just didn't sound right, but I figured maybe it was still a little cold. Continued driving, and it stalled out ( zf6) , I tried pop starting it but that only got me another block or two, after 10 minutes of cranking I got it to start up made it a half mile it shut off, same thing started and got it home. It cranked longer than normal but started at home after it I turned it off.
At work now so I have yet to check anything. Replacing CPS after work No smoke out of tailpipe, It is getting fuel, I checked the filter. I am no master mechanic, I do basic maintenance like oil changes, brakes, filters and censors my self. Anything more intensive I have not done. If it is not the CPS what else could it be, and how would I go about checking?

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 2002 F-250 with a 7.3.
I have been having a no crank, no start issue off and on for a while. batteries are new, cables are new, connections are clean, and starter has been rebuilt and checked. I bought a "starter relay" which i thought was the top solenoid in this picture. I also replaced the lower solenoid in the picture. The bottom solenoid was replaced with what im sure is the correct replacement. The upper I think is wrong. It started but then shut down and will not restart. The upper solenoid also was very hot after it shut down.
Long story short what is the upper solenoid for? Im assuming its not the starter solenoid. If so where is the Starter solenoid on a 2002 7.3?

I just got a 02 f250 lariat 4x4. 7.3. the dimmer on the dash will not work. The light switch was falling apart any way so I replaced it with motor raft switch. Didn't fix it I checked the fuses for the dash and lights. Can't find anything. It does have an aftermarket CD player and those light work with switch. Also it has the mirrors with turn signals and run lights. Neither works power mirrors work fine but no lights. On either side.

I have some LED strips i bought, some i am going to install under the door sills to light my nerf bars/steps. The rest i am installing under the bed rail to light the inside of the bed. I want them to come on with the interior lights. So when i hit the unlock button on my key fob, or open the door said lights will come on.
