LS2 swap starting issue

[davidomilligan]

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?
