mustang899193

I parked my mustang in the fall I went to start it up and the fuel pump would just run so I put a new one in it... It still didn't start so I tried the fuel pump relay that also didn't get it I also tried the tfi module still nothing and lastly I tried the fuel pressure regulator I'm getting spark... I was gonna try and switch ecms with my 89 to see if that was it and I was wondering if it would work before I did it
