97 Mustang 3.8 to 5.0!

I've done a 94 3.8 to a 5.0 (see the link in my sig); all the 94-95 Mustangs share the same wiring harness so the swap was relatively easy. I don't know how or if the chassis wiring on the 97 is different from a 94-95, so I'm not sure if I can help at all. According to RockAuto, the OEM fuel pump in the 97 3.8 is the same as the 94-95 5.0, so that should not be a problem. The fuel pump gets it power from the CCRM module; it's the box attached to the coolant reservoir bracket. It has relays for cooling fan, fuel pump and overall engine electrical. If the fuel pump relay has failed the pump will not prime. You may also want to check the fuses in the fuse box under the hood and make sure none have popped.
