It's been a while since posting here but.... I thought if I could get an answer this is the place to do it !
My 1996 F-250 Diesel three weeks a go began running extremely rough so I called my mechanic who said bring it over...almost didn't make it. Said he'd look at it tomorrow. He called the next day and said both gaskets and the harness were toast and recomended changing all the glow plugs. Got the parts, installed them...still runs bad. He suggested 3 injectors could be bad...found some used ones known to be good and installed them to no avail. Now he says the firing of the injectors is erratic. Still no success. I have 384K miles on the truck.
Could the injector controller be the problem ? If not could anyone offer some advice. I would really appreciate some guidance.
He said they were getting fire but not working....now says firing is every now and then. That's what makes him think it's the controller . I don't know what codes were set. Thanks for your input !
