1996 Chevy pickup cruise control problem
C Nash, Thanks for all the responses. We live in Az, Hot, now on 3rd injector pump and 2nd lift pump, have always changed oil, air, and fuel filters, never seen any water in drain can I put under hose. Am reasonably mechanically literate, MEngineer background and inventor, though now I lend money for the RV industry, go figure. This is my first diesel engine and I feel lost working on it, though it's just another engine with less parts I guess. Extended driving does not seem to matter in the shut off. When the last pump went out it did seem to shut down as it heated up and a couple of times it presented a dangerous situation. Now it only shuts off for an instant, not like when the injector pump controller was going out, almost like a loose hot wire to the controller as if it were just sitting on the spade and not fully pushed on and would jump off for a millisecond and land back in place? Do not understand your "watch your tac and see if the rpm jumps" statement? Will remove the cover tomorrow and instal a new fuel filter and check the connections on the pump controller, and check the brake pedal adjustment.
