Let me first start by telling you that I had a bad accident and ripped the front end off of my 97 Ford Mustang 4.6 L single overhead cam I then proceeded to remove motor and transmission and most of the wiring harness and plus dash. I then proceeded to purchase a 95 body and remove the V6 and transmission and most the wiring harness that I had planned on Switching out with the old anyway. After about a week and a half of working diligently. I with the help of my very close friend we completed the swap unfortunately for me not knowing much about Electronics I found out that it would not start nor would it get fuel I proceeded to bypass the switch and run a hot wire to the fuel pump and bypass the switch and run a wire and a bump starter button we got it to run we drove it around the neighborhood on returning a day or two later preparing to weld the exhaust back on noticed that it wouldn't start it would just crank and turn over and turn over and turn over now I'm sitting in the front seat turn the key switch on hitting a bump starter it will run for just about 3 seconds and then shut down the anti theft light is flashing rapidly and after a little while it will stop flashing with the key switch on somebody please help me to figure out what the problem is so I can pull this car out of his driveway and take it home thanks a lot
