Ford 7.3L Power Stroke (1999-2003) :: Truck Was Shutting Off While Driving

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...

Ford 7.3L Power Stroke (1999-2003) :: Cackling Noise At Idle And While Driving?

I had a piece of an exhaust valve break off and as one knows, that requires an engine rebuild. I have a rebuilt engine with new upgrades to my previous upgrades; fluid dampener, chrome moly push tubes, billet flywheel, T-500 HPOP, new front cover, up pipes, Dieselsite ball bearing turbo, OEM rebuild kit, comp cam valve springs and all new valves. Had some issues with the Dieselsite turbo that was worked out. Now I have a cackling noise at idle and while driving. The noise momentarily goes away for about 2-3 seconds while accelerating, (actually gets very quiet) but the noise returns. It doesn't seem to effect my performance, just very loud. I performed a cylinder contribution test, (passed) and injector buzz test, (passed).

Ford 7.3L Power Stroke (1999-2003) :: F350 - Surging And Rough Idle While Driving

I have an early 99 F-350 with 268K miles. It is bone stock right down to the factory exhaust. A couple months ago I started have a rough idle and surging while driving problem. I never got a check engine light but I borrowed a scan tool from a friend and pulled the following codes: P1690 (wastegate solenoid), P0381 (glow plug circuit malfunction), P0269 Cylinder 3 Contribution/Balance Fault, and P0284 Cylinder 8 Contribution/Balance Fault.

I did some research and everything I read said it was most likely the CPS. So I changed the CPS. The truck ran fine for for a few days but then it started acting up again occasionally. I noticed that most of the time when it acted up was at start up when the engine was cold and I also figured out that if I shut the truck off and re-started it (sometimes I had to do it 2 or 3 times) it would clear up and run normal.

A buddy of mine that has a 2000 F-250 said he had a similar problem with his truck and it ended up being the ICP sensor. We switched his ICP with mine and I changed my oil at the same time (because it was due for an oil change). My truck ran flawless for over 2-weeks (over 200 miles) so I put a new ICP in my truck. Note: my buddy did not experience any problems with his truck with my ICP in it.

I've put about 700 miles on the new IPR and the truck has started to act up again. Once again shutting the truck off & re-starting it will clear it up and still no check engine light. I took it to a local "diesel specialty shop" while it was running rough and they hooked it to their scanner and got P1280 (Inj. Control Pressure Low), P1690 (Wastegate Solenoid Fault), P0381 (Glow Plug Indicator), P0269 Cylinder 3 Contribution / Balance Fault, and P0284 Cylinder 8 Contribution / Balance Fault.

They never did anything other than hook it to a machine & check the codes but their diagnosis is my High Pressure Oil Pump is going bad and my #3 and #8 injectors are going bad. They recommended I let them replace all 8 injectors and the High Pressure Oil Pump. The problem I have is they can't give me a REASONABLE explanation as to why re-starting the truck a few times clears up the problem.

Ford 7.3L Power Stroke (1999-2003) :: Shutting Down When Hit Any Occasional Bump

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.

Ford 6.0L Power Stroke Diesel :: 2003 - Surge At Idle After Driving For A While

My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?

Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.

Ford 6.0L Power Stroke Diesel :: 2003 - Engine Shutting Off

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.. ??

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smooth Idle But No Power

I purchased a 2000 excursion with the 7.3 a couple of weeks ago. The guy said originally in the add that it need #2 and #8 injectors replaced. When I went and looked at it he had already replaced them and said the it still has no power and needed the remaining 6 replaced. I purchased it as it was a good deal thinking I should be able to get it fixed for worst case a set of injectors. BTW the engine has little to no blowby and starts easy and idles great.

The problem it it will not build any boost (has external boost gauge). Actually the gauge only shows vacuum. With the truck in park or neutral you can slowly rev the motor to 2500rpm and all seems fine but as soon as you break past 2500rpm it sound like it is missing and starts blowing white smoke. The smoke smells like when a diesel heater runs out of diesel. If you try and drive it it has NO power and will not move out of its own way and will eventually start like it is missing and blowing white smoke.

The previous owner replaced the following:

#2 injector
#8 injector
UVC gaskets
MAP Sensor
Wastegate solenoid sensor

The first thing I did was start looking at the no boost issue and pulled the turbo. I deleted the EBPV while i was there. Also the turbine wheel was in very bad shape so i replaced the turbine wheel, shaft, seals, bushings and installed a new compressor wheel 5+5 wheel off ebay. Reinstalled turbo and the symptoms are the same. I also replaced the clamps on the spider with Tbolt clamps instead of the worm gear styles and it psi tested all piping and intercooler to 30psi with no leaks. Also the up pipes have already been replaced with the bellowed style so there are no leaks and it has a 4" straight exhaust.

I have since ordered oring kits for the injectors and also ordered the fittings for the fuel bowl so i can check fuel pressure. it has a new air filter, oil filter, oil and fuel filter installed.

The ICP sensor has oil in the plug but if i unplug it the symptoms are still there.

I have also used a scanner and the ICP pressure is approx 500psi at idle and the duty cycle is about 11% at idle. Also the HPOP looks to be new as it is very clean compared to the surrounding parts and i have checked the HPOP reservoir and it is full to withing 1/2" from the threads.

2000 Excursion
7.3
205000 miles

I am assuming that the injectors are original other than #2 and #8.

Ford 7.3L Power Stroke (1999-2003) :: 2001- Rough Idle - Power Loss?

Dad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - CEL - Rough Idle - Loss Of Power?

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.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F550 - Surge Off Idle / No Power

I have 01 F550 6spd 4x4. sounds rhythmic, smooth at idle but just over 1200 is a pattern surge but doesn't sound like one cylinder, cel is off, ICP and pigtail changed as it was leaking , no change. From what I've read duty on ICP and IPR should be about same % I've included the codes I've gotten, I have the epc disconnected right now as I thought it was a wastegate issue, checking the ICP plug next,anything I've missed? It had a cyl 8 contribution at idle which I hear is common? Will changing CPS work with that one? Think it's a grey one. There's no water in bowl I replaced filter, since replaced ICP, pigtail, and bleeding fuel bowl and new filter the codes are gone but still misses, will be checking uvch, injector buzz test showed no faults. Old diesel guy said to flood with Stanadyne fuel treat?

Ford 7.3L Power Stroke (1999-2003) :: Idle Roughly - No Power - Got Codes P1280 And P1316?

Started my truck yesterday and drove about 1/4 of mile and all of a sudden I lost all power but was lucky enough to creep back home. Had a friend put it on a scanner and it spit out P1280 and P1316 codes. My truck will start and idle rough but has no throttle response and no power. I changed out the CPS and ICP and the problem still exists. I got an infrared thermometer and checked the heat coming off each manifold and the driver side was reading about 200 while the passenger side was reading about 75 while at idle. Pulled valve pan cover off the passenger side to check and see if the harness came loose and everything looked fine. So my question is do you think this could lead to a bad IDM?

Ford 7.3L Power Stroke (1999-2003) :: 1 - 2 Second Power Loss While Driving

I have been getting about a 1-2 second power loss while driving. happened last friday when at a stop light, pressed the pedal and started to go then it dropped out for a second or two and then caught right back up. only cut out twice in 10 minutes then ran fine for another week. This friday oddly enough , it happened again while driving down the road. happened about 5 different times in 10 minutes, then back to normal. I replaced the passenger uvch with dorman, but not driver side a couple of months ago . Does this sound like the other uvch, or tps?
