Thank you! After some of the input from this thread I realized it’s possible that the PCM might be shutting down the fuel pump because of the APPS codes for both APPS signals. No, I’m not jut reading codes and replacing parts. Yes, I can clear the codes with my scan tool. In fact, when I got...

I bought the truck new. It has 52K miles on it. This started with A/C not working. Took it to a local repair shop about 4 years ago. They hooked up their Snap On Solus and said “dash controller is bad or PCM is bad, can’t tell for sure”. I replaced dash controller. Still no A/C. I pulled the...

Thanks!

Thank you!!!

No, I measured it with the relay taken out and probing the socket in the TIPM that is the output from the PCM.

Yes, I did change the relay. Put a new one in. Testing continuity between theTIPM relay input socket to the connector pin for the PCM, I get 0 ohms resistance. So no problem in the wiring from TIPM relay input to PCM output. When I read the voltage at that same socket (input from PCM to relay...

I need a recommendation for PCM repair. I’m getting P0628 low voltage at fuel pump. I can turn the fuel pump on by taking the fuel pump relay out of the TIPM and applying 12 volts to the fuel pump through the relay socket. The schematic I have seems to be wrong? The schematic shows relay pin...
