98 chevy 6.5 had a hard start problem and ran rough till it warmed up, the problem just kept getting worse till it just stalled, while running rough took it to the dealership they had me change the lift pump,and fuel shut off. Since then had the fuel injecter pump tested twice, changed the ignition,oil sending unit, had it hooked to another computer and showed no faults, as of now have fuel to the pump but not comming out

 

you need to get the air outa the system and get the pump primed with fuel

 

and how would i do that? Bleed the system up to the fuel shut off , the lift pump got good pressure to there

 

I would crack the injector lines where they go into the head

 

took the lines off right at the back of the pump, no fuel

 

OK.......I guess start at the discharge of the lift pump and move forward from there till you have all the air out

 

bleed it at the filter, then at the two points it goes into the pump, cracked the fuel shut off valve, beilieve I got all the air out as far as I can

 

so yer primed right up to the inlet of the injection pump then??

if this is the case I say get the lift pump running and then turn the motor over so the injection pump has opertunity to pick up the fuel....... once yer internal pump gets a prime on the fuel it should start delivery to the injectors.................just make sure you have loose lines at the injectors or the discharge of the IP when you do this

 

i'll give it a try and keep you posted, thanks

 

Please update.
