I bought a m1008 a couple months back for the drivetrain, but its really not in too bad of condition so I am trying to start it. It was missing an injector pump, I've got another one installed but I am not sure its good. The glow plugs all test ok, but I dont see anything in the service manual about testing the pump or injectors, should I just hook everything up and wing it? Does diesel fuel go bad? I know it hasn't run in at least a couple years, should I drain the tank and put in fresh fuel? Any suggestions would be appreciated. Tried the following but it still didnt start: Drained old fuel and added new. Removed glow plugs and cranked till it had fuel at the filter, then hooked line to pump and cranked until fuel came out at injector end of fuel lines. Hooked lines to injectors and installed glow plugs - wouldnt fire. Decided to try everything again, but now I have one glow plug that wont come out of the head. Replaced the other seven with 60g's - still doesnt start. Glow plug solenoid and the fuel solenoid are cycling. If I get it started can I disconnect power and just leave the mushroomed glow plug in? Is there any way to get it out without pulling the head? How big is it? Maybe through the injector hole? It is timed the way the book says, housing mark aligned with front cover and pin on pump through hole in driven gear. I have another complete set of injectors(but don't know whether they are good) that I am going to try when I pick up the right size socket. Anybody have any suggestions?
