Got the 2000 f-550 Jr wrenchwagon in shop today. Running very poorly, no power, no smoke, will not hardly even move. Plugged in Shows 1 ,3, 5, missfire. Have any of you all seen this one or have much exp with a Powerstroke? Looking for helpfull insight. I suspect a broken harness wire. Will tear it down in the AM. Thanks
Wrench, check your wiring harness that goes through the valve cover gaskets. A lot of times the glow plug wires get hot and start to short out the rest of the harness. More than likely thats the culprit.
Thanks for the feedback, We only have 1 powerstroke, most of the company vehicles are gm.
Yep, I think I'd try switching valve cover gasket with gasket on opposite side of engine if you don't see anything that's plainly obvious.
what works best is to remove both valve covers and place a cummins under them
If your going to all that trouble just put a CAT in it.
3408 DIT, now your talking!
Yea I would say either the harness or possibly the IDM.
wrench that is what FORD spells backwards Driver Returns On Foot not good when he the mechanic but i have fixed the valve cover gasket on several buddies trucks it is quite common problem i know a engineer for Ford drivetrain he even says that the wires in the gasket was a bad idea but it made it out of warranty
Driver Returns On Foot ha ha ...That reminded me of one of my buddies tellin his boss " If I keep drivin that truck I'm gonna have to get a Dog " boss sez " dog ?? " his reply "that way I won't be walkin by myself " ...
Thanks again for all of the help. Finally got enough time between the loaders and rock trucks to work on it. Here is what we found. Number 3 injector shorted out causing 1 and 5 to also show up as misfire. Oil leak on high pressure oil pump, (HPOP). Replaced injector #3 and re sealed top gasket on pump and all codes cleared up runs fine. Injectors are pricy.
if you ever had to buy a duramax injector the ford HEUI injectors are CHEEP!
agreed
