Question about 1990 GMC C1500
Very close to scrapping entire project...absolutely disgusted...
90 chevy truck, 1500, 6.2 diesel. Blew head gasket, water in oil, ect. (300,000 miles)
Bought very nice looking 6.2 diesel military pullout, trying to start outside truck. Changed out injection pump solenoid, hooked 12v to it, put on new starter, battery, new lift pump at injection pump inlet, took out glow plugs, took all hard lines loose at injection pump to bleed diesel, cranked engine over forever. Very little seepage at line connectors.
Swapped out injector pump and lift pump. No change in seepage, but am getting return diesel from top of injection pump.
I should be getting fuel SPRAYING out of injection pump where the hard lines connect, right???? There is no manual bleed on this system.
What the heck am I doing wrong??????
Make sure all lines are light when turning engine over.While turning engine over loosen the a line closes to pump or the fuel filter.You should get some fuel.Then continue on all lines working farther away.
