Ford 7.3L Power Stroke (1999-2003) :: 2002 - Engine Shutting Down When Hot
Aug 30, 2016
I have been battling and issue with my 02 7.3 just shutting down on my at random times.
1st Time
Outside Temp: 100
Drove 5miles sitting at in idle in bimart parking lot truck shut down
Let sit overnight, went back started right up
2nd Time
Outside Temp: 100
Driving home sitting in traffic slow moving 5mph, truck shut down
Able to start up about 5mins later
3rd Time
Replaced CPS, Air filter, Fuel Filter
Outside Temp: 80
Hauling travel trailer up peak 35-45mph shut down
Allowed truck to sit 35-45mins started back up
Started hauling made it about half mile shut down
Got towed to flat land to unload trailer and haul the rest of the way
Returned to truck
Started right up 45mins later, drove it 30miles home without a problem
I am at a loss i keep reading and seeing HPOP, tin nut, IPR, EBR..
The last post I read was about the IPR : [URL] .....

I have a 2003 Excursion 6.0 with edge juice with attitude
While driving first thing in the morning runs like a champ, as the engine warms up I start seeing the exhaust temps lower to 88-94, then I start getting over boost code with monitor reading of 41psi, then the Edge monitor screen will go blank, then the STALL... The excursion with start right back up but the shut off immediately. Wait 20-30 minutes in the shade and will start back up and run again poorly missing almost like turning the key off and back on... Then the next morning start all over again.
I'm thinking bad FICM or bad PMC over heating.. ??

Last week the engine in my truck was shutting off while driving. Happened to me 3 times over the course of two days. The first couple of times, the engine was dead for 3-5 seconds and then the engine would come alive and drive normally again. The third time was about a 10 second event...same result, engine refired on it's own and drove normally. I was in motion all three times so the engine restarts all occurred before I was able to bring the truck to a complete stop.
No check engine light...(I didn't pull any codes because I didn't have my laptop with me). So, I decided to try a new CPS. I had one in my glove box since 2003 so in it went. It replaced a black CPS that I purchased from Riffraff about 100k miles ago. The new CPS seems to have done the trick. I've driven about 500 miles since the swap and the symptom has not returned. I wonder how long this one will last. It's a Ford replacement part so maybe I'll get another 100k miles...

So I have this intermittent problem of the truck shutting down on its own when in idle or idling along in drive I immediately put the truck in N, turn the key and she starts right up again.
Does not do it at speeds, just in idle. The "check gage" and "battery" light are the only dash lights on after a shut down.
Where do I start?

I have a 2000 F250 superduty crew cab short box. It has any occasional issue of either just shutting down (engine dies) which seems to happen if i hit an occasional bump. The other issue has happened a couple of times which is it will lose power and just go to a rough idle. I shut it off and restart it and it will run fine. I'm wondering if it is the throttle position sensor.

So after hitting a pothole, it would seem like half the engine lost power, after some searching around, i found that i would most likely be the harness inside the valve cover that has lost connection.
Its the right side, so i would need to take of the turbo pipe, and probably something else to get to it.
Since i'm doing this job, what to check out along the way? I want my 7.3 to be as reliable as possible.
I will probably ask some questions along the way, it can be a challenge sometimes to own a car that not many mechanics are familiar with, but as i have read online, this should be a very straight forward fix.
Can the harness be upgraded so it doesn't happen again? Its an 02

My VIN inside the door is scratched enough that the State can't verify it. They need two locations to match the VIN otherwise the vehicle must be scheduled for a "level 3" vin inspection hundreds of miles away. Well I tried to find one on the engine where the DMV can do a "level 2" vin inspection but I can't find it. Where other vin's are on my 2002 Ford 450. Mine is a flat bed.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

so got to work today, truck engine light comes on all foward motion stops. Just coasts and idles along. I have 280k on the orig stock trans. I also have dp tuner and did the valve body upgrade along with adding the 6.0 cooler hoping to extend the life of the trans. Reverse works. So i asume I am needinf a new trans. My options are Ford HDr4100 orig 4100, Or BTS built trans. I also pull a toy hauler as well. My question is If I order the BTS can I have a my local shop install it or does it need to be programmed at the dealer. If I get the HD from ford installed will I have to remove the dp tuner chip to get it programmed and also will i need another new valve body replacement.

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 2002 excursion 7.3L. It has started dying lately after I let off of the pedal and the vehicle slows down and the engine is supposed to go to idle but sometimes it dies. It will start back up right away. It has begun to start a little rougher especially after it dies. I have replace the CPS and I got new batteries.

02 7.3L SD Im on a long haul and think I might have bought some bad diesel. It is shuddering a little kind of like a miss. It started right after I stopped for fuel. Is this going to damage my engine to keep plugging along? Is it just going to run kind of rough until I burn up the bad fuel? Ive got about 200mi to go so just needed to know if its safe to keep driving or am I going to be stranded.

The truck is a 2002 F450 7.3 diesel with about 120k Miles.
While driving from 45-70Mph the truck engine stops for about 1 second and starts back up by itself. I thought the problem was the cps so I replaced it with a ford CPS. Today the problem still persists. The truck engine turns off and comes back on, the tach drops to 0 rpm and so does the speed.
The Check Engine Light comes on and so does the water in fuel light and so does the Check Gage light. After I turn off the truck and start it back up the truck does not show the lights.
I believe I found the issue, but can't look into it today. While I was moving some of the wires on the truck I found out that if I move the red/black bunch just a little bit the truck shuts off and comes back on when i let it go.

2002 F350 7.3 PSD. 192k miles.
From my understanding, a CEL is supposed to illuminate each time you turn the ignition ON as part of normal startup procedure.
I figured the previous owner must have pulled out the bulb to hide the fact that the truck had a few "issues" before selling it, so today I pulled out the gauge cluster and it looked as if the CEL bulb was a tiny LED soldered directly into the gauge cluster itself. There were a few serviceable/removable bulbs for things like turn signal indicators, high-beam etc... but the CEL did not have a serviceable/removable bulb.
I've been driving this truck and working through it's "issues" and fixing things as I go, but it keeps throwing codes without the CEL illuminating. What's going on here?
I thought the check-engine-light was supposed to illuminate each time the ignition was turned on, and that it would come on each and every time the vehicle registered a fault code in the ECU/PCM.

2012 6.7 F250 with 17k miles. It's getting hotter here and the last couple of days when shutting down there is a sound coming from the engine compartment that sounds like an air pump on one of those load-leveling systems. It will go on for about 15 seconds then stop.

I have a 2002 7.3L Screw 4x4. Will a 03/04 6.0L instrument cluster work in this truck? The 2 clusters appear identical. I put the 6.0 cluster in and the trans temp, and coolant temp gauge will not work. All the gauges sweep when it is powered on, but the coolant and trans temp lay flat, and the check gauge light is on. All other gauges and functions work. When I put my other cluster in, all gauges work fine. Is there a difference in the VSM, PCM, or the SCP communication?

I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).

My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.

I have a 02 f350 7.3 with 296,000k its been running ruff lately with a serious loss in power. The truck sounds good at idle starts up fine but when im on the throttle under load it almost crackles and sometimes bucks. I thought its was injectors replaced them all with stock ford remains but didn't fix the problem. I have AE and it passes a buzz test but i did a KOER test today and it started what seemed like a misfire during the test my ICP went to 2400-2500 and my IPR was at 38%. I have already put a new hpop in a couple month back along with new hpop lines do to a burst, ICP sensor, and i rebuilt the IPR valve. Not sure if this is a problem with fuel or the hpop I have also cleaned the screens in the tank and replaced the fuel pump which were pretty bad....

I have a 2002 F-250 7.3, 159k on it. I bought it in March, ran AWESOME up till now. I was driving to work last week, check engine light came on, truck lost power and started idling rough. I have a buddy who works for a Ford dealer as a diesel mechanic, he came over with his scanner and laptop. #2,#4,#8 cylinders kept coming up saying possible problems are injectors, harness, rings.. He also did an electrical check, that all checked out. He told me to get injectors, so I got 4 injectors (yes I got the correct #8 injector), valve cover gasket, injector harness and 4 glow plugs.
The parts came last Friday, we did the job and it ran great. Drove it Friday night, Saturday, Sunday morning, no issues. Sunday afternoon we were on our way to a birthday party, truck started doing the exact same thing... Check engine light, rough idle, loss of power. After I got home from the party, my buddy came back over, put it on the scanner again, getting the same codes again. Deleted the codes, ran the tests again, same codes, deleted the codes, rant the tests again, same codes.
He said he is going to come by tomorrow with the box to check each individual cylinder.
