    Check hall effect switch in the distributer, or wiring from the computer, injector drivers are a ground from the computer.

    FIRST thing to check in a case like this is....how 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?
