Just got a Cutlass Supreme diesel. Hasn't ran in at least 8 years but it was well taken care of when it ran. At first she wouldn't crank over, but I replaced the starter solenoid, drained the tank, and replaced the fuel filter. Now it'll crank but she wont start up. There is fuel getting all the way to the injection pump. I'm afraid my problem stems from the pump or the injectors, but I'm unsure of which. Any thoughts? Also, my solenoid or one of my connections to it is sparking right when I first turn the key. I've re-routed my positive cable down to it thinking it was the problem, and no wires that I can tell are touching anything they shouldn't. Is this possibly a ground problem?
