You're ECM has the VATS deleted? I went thru that with an LT4 Astro conversion. All ready to go and it would pop once and spin. Went and found a vats module with the correct keys and problem solved. Didnt use the keys, figured out the resistance from them and emulated. Later deleted the vats. Just a thought. The fuel pump should run when jumped regardless of anti theft system. Those grounds are beneath the drivers seat under the truck.

Hey everyone sorry I didnt get any notifications so I thought this thread was dead lol it turns out my tune was way messed up and the pump wasnt seeing signal. That's after I rewired my fuse block and double checked all my grounds and feeds lol... thanks for all your inputs though I appreciate it!
