Is my LP shot?
New member here. I've had 4 Duramaxes before selling my last one and stumbling upon a rusty 1997 single cab Sierra for $1800. I'm a fan of this truck already, even though it's going to be a major project to restore it.
Today I was changing the oil, as well as doing the fuel filter. Everything went fine, except I couldn't bleed the fuel system. No fuel would come out of the little bleeder opening on top of the filter, and I could not hear the lift pump working. I put the old filter back it (it's disgusting!), still no luck... jumped the relay with a wire, still nothing. Finally after several hours of messing around with it, it finally sputtered to life and now runs as it did before. In those 2 hours of jumping the relay, swapping filters, and cranking it over a lot, I did hear the pump kick on only once. It's pretty rusty... I'm guessing it's shot? But if so, how is the truck running without it functioning? I crawled under the frame with the truck running, and it doesn't seem to be making any sounds.
