Fuel pump in tank shuts off. Hello all.
First, I apologize, I tried searching but could not find the issue Im looking at.
The thing is, I got aFirebird 1997, originally a V6
Swapped a 6.0 Lq9 in it.
Got a new harness, new ECM(Vats Deleted)
Got 60psi fuel pressure.
The problem: Key on, it primes but does not stop priming…..
Key to start, starts up just fine, shuts off fuel pump, runs for about 6-8 seconds.
Im not sure but guessing some signal is mixed.
Any help would be very much appreciated🙂

There are wires that are hot during cranking, and wires that are hot any time the ignition is on. It sounds like your new harness needs going through and checking. There could be some other issue, but that is where I would start.
