Won't start

[mustang31]

Hello

I have a 1993 mustang that was a 4 cylinder but we just changed it over to a v-8. The problem I'm having is that once you crank it and let it run for a minute or two and cut it off it won't crank back up. We have changed the coil, distributor, coil wire and wiring harness to the computer and the computer itself. Am I missing something. I was told that as long as I was runnin a manual transmission it didn't matter which computer I was using as long as it was for a car that had mass air on it. I can't think of anything else to try. I have 30lb injectors a t-rex fuel pump and a 255 pump in tank. My regulator is set a around 40lbs. I am also running a paxon supercharger. I have a few other goodies on the car but none of which I think would have an affect on the car cranking. Is the a difference in computers A9L and A9O?


Thanks in advance
