I have a Blazer that's been sitting up for at least 2 years. It has a 4.3 CPI (W). I've changed the fuel pump and filter, drained the bad gas. What I need to know is how to clean the rest of the fuel system?
It will run only if I pour gas in the intake. The person that had it before me said that it just quit running as he was driving. So he set it up and bought another vehicle.
have the same problem?

Does the fuel pump run? Do you have good pressure at the engine. If so it may not have injector pulse. There is a 2 wire plug at the front d/s of the intake manifold that goes intot eh upper plenum. Use a test light to see if it has power on one side and the other side should flash when engine is cranked.
