Hello gents,
got an issue with 91 camero, did the swap to the 400. left all wiring and i am using original trany. i put in a aftermarket pressure regulator with a bypass to use the original fuel pump. i have power to starter and can remote start it or turn it over. I dont hae fuel pump and have tried recommended by pass methods, and i dont have start off of the key. any help greatly appreciated.

VATS is probably worth disabling. I have it disabled on my 92 and it always gave me a headache on my 89.
And, also, why did you keep the wiring? I dont know if its the same on a 91, buuuut on my buds swap in the 86 we basically ripped out the entire engine management harness and kept the chassis harness. It was easy to wire up some of the other stuff and made for a much nicer engine bay. My $.02
