Ford 7.3L Power Stroke (1999-2003) :: Some Gauge Reads Towing Light
Towed 3 axle trailer loaded with a 73 VW bug, two implement bars, plows and a small boat. I would guess total weight at 7,000 max. The ambient temp 97 degrees and very humid. I have a 2000 dually.
The following are from the ScangaugeII
TFT trans temp 175 max
EOT end oil temp 205 max
SLP trans slip 0.20 max and 0.0 in high gear
From glow shift
Water temp 196
The one I am worried about is the trans slip, from a stop taking off always went high 0.15 to 0.20 and then drop quickly. Once the TC locked 0.0 down the road. Also, when I reverse with no load on dirt I have seen 0.20 on the trans slip. I have Forscan but have not logged any temps yet....

I bought my 2000 7.3L Ex as salvage back in 2005. It had been through a driver side rollover and the seller had restored it. We lived in North Idaho then. But I remember I always had an issue with the check engine light being on. I don't remember what the codes said, but many mechanics read them and determined that nothing was wrong. Many surmised that someone had put a high performance chip in the computer and that was what was causing the check engine light to come on. All of them reset the computer and every time it would come back on. Should I replace the computer?

1999 f250 7.3 101k California truck ... Scanned it said #1 glow plug did not clear the code. But now the check engine light is off again...
Questions : Harness issue ? Glow plug bad at 100k ? Glow plug controller ?
Start at glow plug work way back to GP CM or in reverse ?
Replacement Do all 8 or just the bank of 4 ?
Thoughts on replacement brands
Accurate diesel glow plug replacement kits any good, will they last ?
Or go factory glow plugs
What about Felpro gaskets
I heard about another brand of GP CM
Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light On / Cylinder 5 Misfire
So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong. Any way to check what's wrong myself?
Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...
Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light Briefly On After HPOP Rebuild
Now that I have been driving for a while I kept seeing this light come on/off and I did a video below - I don't generally flash my lights so don't think I am aggressive - but I wanted to make sure to capture the video and the light coming on.
I was thinking valve cover connection the 50 cent mod - and maybe it's all coincidental - but I did have to pressure wash the troph where the oil collects and maybe something else got knocked loose.

Ford 7.3L Power Stroke (1999-2003) :: No Throttle - Check Engine Light Came On When Pedal Is Depressed
I have a 2002 F250 4x4 Powerstroke with Automatic. I have been having off and on issues for months with the throttle going dead. This only happens when I start it, if it works when started it will continue working until a different start session.
I have replaced the pedal several times before learning how to check its output with a meter and am quite sure that is not my issue at this time. However, when the pedal is depressed the check engine light lites up and nothing happens.
I am thinking it must be the computer itself, but was told there is another sensor or module under the hood that could cause the issue also which is several hundred dollars to replace as would be the computer.
Is there a way to test the computer, and what is this other module/sensor if it exists that could be the issue? Unhooking and rehooking the battery to reset the computer is no longer working to buy me a few more weeks, is there a simple way to reset the computer to try?
I love this truck when the throttle works but I am getting tired of paying on a truck while having to borrow a vehicle to drive to work.

View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Runs Rough Then Stalls - Check Engine Light Came On
I have a 2001 F350 with the 7.3 standard trans. The previous owner put a toggle switch to control the EBPV as an engine brake, I've never used it. It blows white/blue smoke when cold but has for the last 4 years and doesn't seem any worse now.
Last fall I ran the truck the lowest on fuel that I ever have, the light was on for a long time and I thought I would run out. I made it to the gas station and filled it up then drove home. The next time I drove it I went about 25 miles and it started to buck while going up hill. This got worse and eventually the check engine light came on and it stalled.
It wouldn't start again so I had it towed home. I got it started a couple hours later but it would run really rough and only for a minute or so then stall. It will usually start again once or twice and stall, then it wont start again until it has sat for an hour or so.
I didn't have a code reader at the time so I started reading threads. Here's what I've done to date.
Changed the oil and filter, it was way over do. New fuel filter.
The oil level in the HPOP stays about an inch from the top, I've checked it a few times after its stalled.
Dropped the tank and cleaned the screens in the pick up, no change.
The ICP had oil on it so I replaced it and a new connector, no change.
Changed the CSP with a grey one, no change.
Changed the IPR valve with one from a buddy that was on an engine that was running. The truck ran rough for a min then settled down and ran smooth. I let it idle for 20-25 minutes with no problem so I thought the problem was solved. After sitting for a month or so I fired it up and its back to running rough then stalling.
I bought a Vgate ELM327 connector and downloaded FORScan on my laptop. (I'm still not sure what I'm doing). These are the stored codes P1281, P0475, P1316, P0478, P0470, P1211. I cleared all the codes. I did a buzz test cold and the Injectors all sounded the same.
I monitored the truck while running (rough) the IPR is staying around19.92%, ICP is 701.4psi. After 5 seconds the ICP starts to climb and so does the IPR, at 12 seconds the IPR is 37.11 and ICP is 1835.1 psi the it stalls. The fuel pw,ms is around 2.50-3.0 until before it stalls, then its 1.66. The only codes that come up are P0475, P0470, B1473.
Ford 6.0L Power Stroke Diesel :: 2004 - Check Gauge Light On While Going Downhill Towing?
My 04 F 350 started with a check gauge light while going down hill towing an 18 ft car hauler full of mulch. Did it for 5 seconds, then when we got to our land and I was getting ready to back up it did it again. and this time my oil pressure gauge was at zero. I shut her down. checked the oil. its full. Drive home everything is good. Today I'm getting fuel pressure gauge going nuts. 80 to 100 PSI. at idle no oil pressure and the check gauge light. but the engine is still running. Oil was changed 4K ago. fuel filters same. Where to start looking?
View 5 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F350 - Check Engine Light Not Coming On When Ignition Turned On?
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.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - No Power Especially While Towing
I just bought a 2001 F350 diesel with 120k miles on it a couple weeks ago. Friday I headed out to Oregon with my 16 foot enclosed trailer filled with jet skis (about 4-5k pounds) for a competition. A few minutes after being on the freeway I noticed the truck did not have good power. About 30 min later while climbing a steep grade the truck almost went dead.
I started at 60mph and by the time I got to the top i was at 15mph with the throttle pinned. the motor sounded funny and shook the truck more then normal. After wards on the down side of the grade the truck started to act normal. I took it to my buddies house and switched trucks because I didn't trust if for the 13 hour drive.
Today I talked to a mechanic at the dealership and he said that it sounded like injector o-rings to him. I went home, pulled the valve covers and started the motor to see if anything is leaking. steam was coming from the valve area and the down spouts on the injectors was flowing oil. The thing that looked especially abnormal was one of the injectors looked like fuel was dribbling from it. I don't know if that is a problem or not. I couldn't tell if it was fuel or oil but no other injectors had fluid coming out near the wire connections.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Power Loss While Towing Up Hills?
I pulled with my 2000 F250 7.3 for the first time yesterday pulling a 12,500 5th wheel and then again today with an 18 ft ski boat weighting around 3500 for both the trailer and boat. I had this same issue pulling both.
Today when pulling the boat/trailer i was behind a slow moving truck and when we hit a hill with a passing lane i merged over and wanted to start passing him. We started off at around 45 mph up the hill and as I started pushing the pedal I wasn't gaining any speed and my rpm's didn't even get over 1500. It felt like a stall and continued that at around 45-50 mph up the hill (about a 65 degree slope). When I'm not towing the truck runs great, plenty of power and averaging around 16 1/2 mpg.
Only mods i have is a 6647 Napa filter, muffler delete and it's running the same 4 position TS tuner from the original owner. During normal operation I run it at the 75hp gain and when towing i use the 50hp gain.
In both instances i could see black smoke coming from exhaust when pushing the pedal but my rpm's wouldn't go up and truck maintained the slow speed going up the hill. Once at the top it drove normal and picked up speed without any problems.
Ford 7.3L Power Stroke (1999-2003) :: More Black Smoke When Towing?
Normally I run around sea level at home but Iam on road trip in Wyoming at over 5000' elevation I am noticing alot more black smoke when towing. I run a DP tuner with 40 and 60hp tow mode. I also notice alot more black smoke in 60HP Econo Mode when not towing? Would this be typical due to the higher elevation?

I have a 2000 with a six speed and through the first 2 gears while giving it only a little throttle, worse on hills and worse while towing I have a pretty decent vibration. Once you get to 3rd and up its fine. I have read about axle wrap and due to the fact my springs are pretty wore out I think this is a big part of it. Any other things to look at other than new springs? The u joints all look and feel fine so I haven't touched them.

Towing a 5th wheel at about 10,000 lbs total. Towards the end of out 9 hour trip home and going upgrade the truck begins to loos power and the engine starts making some bad sounds. Although its hard to hear it starts about 45 seconds in and continues later when going uphill. the truck also made a very high pitched squealing/scraping sound (not a belt) like it may have been coming from the turbo. Oil temp was about 220, trans temp at 170 at the time of the event.
Truck has 216k, stock, upgraded trans cooler, original fuel pump.
