Just checked the ccrm and found that I have 12.53 volts on Pin #11 (yellow) to fuel pump relay.I have 12.38volts on pin 18 (blue/orange) fuel pump relay input.
But...on pin #5 (green/yellow) i have .33volts. Power to fuel pump.
Is the CCRM toast???
Reason I checked it is that I had a code of 543 -fuel pump circuit open-battery to PCM. The fuel pump whines when the key is first turned on.
thanks.
