Ok guys I’m at the end of my motivation. I have a 2002 mustang gt I bought with a blown engine I bought a replacement engine which came out of a 2003 mustang gt. I have spark, fuel, air, crank sensor is good, cam sensor is good, coolant sensor is good, IAC is good, TPS is good, battery is good, starter is good, all the plugs for the wiring harness are plugged in and the grounds are in the right spot. It’s just crank no start the times I’ve gotten it to start it sounds like I’m running off 2...
