His fuel pump runs continuosly when he turns the key on. He was wondering if there was some sort of sensor that would be fooling the PCM into running the pump continuosly. There is none on this vehicle. The CCRM is the most likely cause. He never said the fuel pressure was out of whack or he had any drivability concerns.
I did clean the contacts between the CCRM and the wiring connector, but that didn't stop the problem. Will a computer read out on trouble codes identify problems with the CCRM? (No "Check Engine" light, and that light does self-test when I turn the ignition on.) Is the CCRM repairable? I imagine that this part is spendy, and electronics are generally not returnable, so I don't want to get one on speculation.
Another hint: the previous owner has bypassed the CCRM and hooked up a direct switch to the radiator fan, so maybe you are on to something.
I didn't mention driveability, because I wasn't sure if that would help to focus on the problem. The car does have low speed/light throttle issues, as if it is terribly lean, or running out of gas, but at more open or full throttle it runs OK (pretty fast too - this is a Taurus?) .
