ls1 swap in 54 chevy pickup wont start

[54chevypickup]

guys i'm new to this site and need some help. I have a 1954 chevy pickup that i have put an ls1 into and i used a painless wiring kit. the computer is stock and not modifed yet, i have a guy guy that can flash it for me but i'm trying to be able to drive it to him. this is what happens, the motor turns over and fires a couple of cylinders and then it shuts down. and the painless wiring kit has a relay plug that is for the fuel pump relay, but i have nothing to connect into it, the relay itself doesn't fit, so i bypassed the relay for the fuel pump.

thanks but i found out what it is, there is a passlock on the pcm that you have to disable before it will start

How did you go about disableing the pas lock? I'm putting an LS1 from a '99 Camero in a '33 ford and probably will have the same problem.
