I have a '99 GMC 2500 SL chassis cab that had a major fuel problem. Over the last few months I've cleaned out the tank (for the most part - the roof of the inside is still a little crusty), replaced 2 of the fuel lines, blew out the other ones and yesterday installed a new fuel pump. Still it will not start!! I replaced the plugs and wires too... Any advice? I'VE GOT to get this truck moving. Thanks

I would suggest diagnosing what could be wrong, rather than throwing more parts at it.

Are you building fuel pressure at the engine?
Are you getting spark?
Are the injectors getting a signal?
