    1987 c20 New fuel pump, injectors not injecting

    Thanks for the help guys. Went out and switched my NAPA battery cause I practically killed it trying to get this thing running. Got all the vacuum hoses hooked up and ICM replaced. There was no frame to engine ground so went ahead and did that. Still no start but I decided buy the pickup coil...

    1987 c20 New fuel pump, injectors not injecting

    Fuel pump died, installed new fuel pump and grinded chassis clean for a nice clean ground. Started right up but stalled on me.
