Hello. I have a 2000 mustang GT 4.6L. I had a car accident but it there were not a big damage. During the fixing process I changed the radiator core support and I did the relocation kit battery. Now my car start but it shutting off in a few seconds. Looks like the fuel is not running properly. I changed the Pressure Switch Sensor, New Pump, New Fuel Pump Module, New Injectors and new CCRM. The problem still. I want to know if the relocation kit battery installation with all grounds cable...

Low Fuel Pressure?
