Hi, I am new here and I was hoping to get some help with my truck.Its a 94 F250 2wd with the IDI Turbo with 185000 miles. Back up to 2008 when the previous owner had it. It would run at the time, but it smoked like crazy at all times. Previous owner drove it like that but got a Dodge with a Cummins and wanted rid of the ford. We worked together and he was having trouble selling it for his price so he told me if I wanted it to work on and play with I could have it for $500. I asked around and seemed like I couldnt get hurt (it has $800 worth of cooper tires on it) so I bought it. I already had two trucks that I was driving ( a 65 ford and a 60 chevy) so the IDI got parked until last fall when I decided I needed a truck with an automatic for my wife to drive when she wanted. A good friend of mine is a certified auto tech and teaches at a trade school so I hauled the truck down to him and his kids got it running. I had tracked down a set of injectors and injection pump from a good running 94 and bought them for him to put in. So they swapped them and replaced all the brake lines and put new brakes on it and did some alignment work on it and when it was done I went down to get it and drove it the 3hrs home.
On the way home it developed a leak in one of the return lines so I got a kit to replace them and just replaced the one that was leaking. I was still having a lot of problems with it taking forever to start so I pulled every injector and put in a new copper seal, new o rings, caps, return lines, glow plugs, tach sensor (tach was bouncing around) changed the fuel filter and engine oil. Seemed to start as good as my dads 95 powerstroke with 230,000 miles. Not in the first turn of the motor, but not after 2 mins of cranking either. The fuel filter light came on and has stayed on since I changed the filter. (it was on before that too though)
On my way to work this morning, I noticed that when i pulled away from the stop sign the engine raced for a second and then dropped back down to normal. It did that at each stop sign. As I was pulling into the lot at work and idling to a place to park, the engine started missing. If I gave it some throttle it cleared up but if i let off and the engine slowed back down it went back to missing. I cracked and bled a few of the injector lines that I could reach without taking the intake off, but it didn't clear up any.
I have read that the fuel filter light staying on is a sign that the lift pump is getting weak, so my first trip to a town with an auto parts store, I am going to pick one up and swap that out. My question is, is the lift pump the cause of my racing and missing problem or do I need to look elsewhere? I am perfectly confident working and diagnosing gas engines, and working on this truck but this is my first diesel and it seems to be a little more sensitive than I was expecting.
