I have spark but no fuel. I had to have it hauled home. To add insult to injury, the guy driving the rollback backed into a tree limb while turning around and busted out the back glass. So now I have a three ton lawn ornament that leaks. Anyway, I couldn't hear the fuel pump run when I turned the key. I put in a new fuel pump relay and changed the filter and now when I turn the key on I can hear the pump running but still no fuel spraying into the TBI. It will start when I pour gas into the TBI, but quits as soon as that fuel is gone. I had replaced the fuel pump a couple years ago. This is my building material/coal hauler so I really need to get it running. Any ideas?
You say TBI and than you say schrader port. The throttle body injection(TBI does not have a schrader). Is this the engine with the plastic upper manifold that houses the spider injector? Or do you see two injectors in something that looks like a carburetor. I need a little more info???
