[QUOTE="2012 Boss 302, post: 15479120, member: 137895"] sorry the image didn't post. P0627 is for the fuel pump control module. Try this read instead.... [B] P0627 - Fuel Pump A Control Circuit/Open[/B] [B]Description:[/B] The fuel pump control module monitors the fuel pump module and secondary circuits for a concern. If the fuel pump control module detects a concern with the fuel pump module or secondary circuits, the fuel pump control module sends an 80% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM. The test fails when the fuel pump control module is still reporting a concern with the fuel pump module or secondary circuits after a calibrated amount of time. [B]Possible Causes:[/B] [LIST] [*]FPPWR circuit open [*]FPPWR circuit short to ground [*]FPRTN circuit open [*]FPPWR circuit short to voltage [*]FPRTN circuit short to voltage [*]Damaged fuel pump assembly [*]Damaged fuel pump control module [/LIST] [B]Diagnostic Aids:[/B] Check for any harness concerns. The fuel pump control module controls the speed of the fuel pump module by supplying a variable voltage to the fuel pump module on the FPPWR circuit.
