Ignition control module or PCM problem or pick up coil ! The CCRM - constant control relay module just has control relays for the fuel pump , cooling fans , A/C clutch coil control , PCM power . Nothing that would make the coil fire continuosly . I would check out videos on youtube test ford ignition system's ScannerDanner gets his but kicked by an 88 150 EEC IV Ignition
Are you talking the ccrm? Those relays are soldered into the circuit board. Some of my ford info, says if the relays in the diagram have no terminal pin numbers, the relays are soldered into the circuit board, you can't pull it out. Sometimes It may be possible to use an external relay, wire it up properly and it should work.
If your talking about the ccrm/ constant control relay module, I'd probably just replace it, if that is the problem.
If your talking about a different relay then, I need more info?
its in a 3 connection waterproof harness now ??????? Do you mean a 3 wire connector ? Three wire's - one black -ground , one is dark blue an the last is brown with a orange trace . He replaced the fan an it didn't fix the problem , imagine that ! Here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html
Enter your vehicle info. year , make , model and engine size. Under system click on engine ,then under subsystem click on cooling fan . Click the search button then the blue link. First diagram is for the cooling fan . You will see to relay's inside the CCRM - constant control relay module . Knowing ford and this part ,i would venture a guess that it was bad . Test B+ power and ground for the CCRM ,if good ,replace it .
In the front passenger side corner of the engine compartment is a black box called the CCRM. Your fuel pump relay is inside this box. There is a 30 amp fuse somewhere near the box on a yellow wire that goes to the box. Check the yellow wire at the CCRM connector for power. If no power, find the fuse and replace it. If it burns again, check the wiring at the inertia switch--I had a customer last week that had a short at the inertia switch that was blowing the fuse. If the fuse is good and there is power to the CCRM, try jumping the pump from the battery positive to the CCRM connector pink wire/black stripe. If this turns the pump on, replace the CCRM. If this doesn't turn on the pump, check the inertia switch and wiring to the pump, including the ground wire. Please let me know if you have questions, and thanks for using FixYa.
