Post the tune you are using ...

The VATS needs to be disabled for starters. If you can post a file that would help.

I'd guess the issue is wiring related.

I'd guess the issue is wiring related.

yea i think so too think the wiring is wrong to fuel pump

ok i turned VATS off

and the car just started , no fuel and no spark

we went over wires and we found out that he forgotte to fasten 2 grounds near the ignition back off the driversside head , we fixed that

started the car , the ignition came in but still no fuel, i commanded fuel pump "on" in the scanner and i heard a click in relay but the fuel pump was still off. No fuel to rails

So would you say that it´s wiring related or am i missing something in the tune maby

thanks

No fuel pump no fire. Fix or hotwire the pump and it should start

I agree. If you're commanding the pump to turn on and you hear the relay click inside the glove box, at least now you can focus on the pump. Hotwire the pump, check it's grounds and such. Get the pump to whine and fire the engine over so you can narrow down the pump's issue.

the guy just called me he went over the wiring again, the pump wiring was right but the power from switch was wrong wired

problem solved and one happy LS1 swapper more
