LS2 swap starting issue
ok so I have a ls2 engine with a holley ecu and harness... when I key the ignition on I have power at the coils but it shuts off after five seconds with the fuel pump....is that correct? when I crank the engine I get power to the coils again only issue is it actually goes to my wires and plugs. I cant figure it out. any ideas?

Sounds like the anti-theft to me.

figured it out my starter wasn't liking my battery being in the trunk with the 2 gauge wire I was running. I put it in the engine bay with shorter 2 gauge wire and it fired right up

Use welding cable for rear battery location.
