1985 k20 chevy with a 6.2
I bled all the injector today and got my engine running for the first time but it would only run with the gas pedal pushed, I ran it like this for a few minutes until the injection lines stopped having pressure. I re-bled the lines but when I got to #7 I could tell from the sound that the rest of the lines lost pressure again. After that I took off the top cover that has the fuel shut off solenoid it hissed from pressure releasing ( i'm guessing that means no air got sucked into the pump?). their might of been a little bit of diesel on the under side of the injector pump but it was hard to tell when feeling it. now this is a new injection pump but the last owner broke a bolt then a tap in one one of the holes that hold on the cover with the shut off solenoid I removed the tap and had the hole welded then I redrilled and tapped it, I use fuel safe gasket sealer in the area of the weld when putting the cover back on. I'm hoping I don't have to buy a new pump but is that my only option?
