I am trying to help a friend with some issues with his 95 cobra. A little background is that he put a motor he had in a fox into a 95 cobra roller. Running a 95 harness and computer(t4mo). One issue is that the fan runs constantly with the key on, no power at fuel pump, not cranking, etc. I have read this could be related to the ccrm or the pcm. The ccrm is new and I can hear relays i am leaning towards the pcm(used). With the fan running I jump pin 55 and 60 and the fan turns off which seems to say the CCRM and wiring are ok as the PCM from what I understand grounds pin 55 until coolant temperature goes above the low speed fan threshold at which point is sends the signal to turn on the CCRM fan relay. Any good ways to test the pcm? Any other suggestions to help narrow his problems?
