Hi welcome to just answers my name is ***** ***** in a stall/no start condition, turn the key off. Check the resistance between pins 6 and 14 of the DLC. The resistance should be 60 ohms +/- 10%.If OK, verify power and ground to the Fuel Pump Control Module (FPCM).If powers and ground are both good, check for voltage on the Dk Green/White wire at pin 13 of the FPCM while commanding the fuel pump on and off via the scanner.If voltage is present when commanded, verify a good connection to the FPCM. If OK replace the FPCM. Programming is required after installation.
