Here goes...Hoping you guys can help me. I have a 1996 Case 590 Backhoe with the 4 cylinder cummins with the Bosch VE pump (pump number is 0 460 424 081. Last year, the machine shut off on me while working. Upon further review, my fuel lift pump went bad. No big deal, ordered a new one and right back in business. A year later, same thing again, it just died. So I grabbed another lift pump, primed it, purged air, etc.... Cranked the engine and I am getting nothing. I checked the fuel shutoff solenoid and it works fine and I even installed a new one just to be sure. No change. At this point, I would like to figure out next diagostic steps. I was going to hook up a pressure gauge to the injector outlet line to confirm the pump is pumping the right pressures. I cannot find any data to confirm what the output pressure should be to each injector. I am also thinking it may have skipped time. I am getting black smoke out the exhaust when trying to crank it over but its not even trying to fire up. Any help would be greatly appreciated.
