First jason,i will say by bypassing the crank sensor,may be the iisue,it not only control,s fire to your plugs, but it all so it tied in with your fuel system,if fuel injected.


First check where the fuel relay is ,for 12 volt,s,this will let you know you have fire at the relay,if fire is there ,that mean,s it is in the wiring going to pump it self.If no fire at relay,check the wiring coming to relay.
