Asked by for the 1999 GMC Sonoma
FIRST thing to check in a case like this much fuel pressure does it have? Need the psi reading! Did you replace the complete fuel spider assembly?? You know that thing under the 'intake plenum' ??? ...Bet you aint got enough pressure!!!!! Will it try to start by spraying a fuel into intake?
