Part of the Constant Control Relay Module (CCRM) located inside right front fender. The CCRM also has EEC relay, cooling fan relalys, etc. The harness goes through the inner fender near or just behind the air filter housing. Need to remove RF tire and plastic fender to access. Black metal box approx 4x6 inches.
just finished repairing this problem on 98 mustang, the fan didn't operate at full speed and a/c compressor had no signal, it was the ccrm, or air cond control module located on passenger side behind plastic inner fender, also accessible under hood if you remove air filter box and reach through hole, the replacement has to have the same large letter on top of module, example, mine had a large S, i think this corresponds to a letterin vin but not sure, but it does have to be the same. controls fan and speed of fan, fuel pump and a/c compressor
"Most Fords have a CCRM (Continuous Control Relay Module) thats on the passenger side fenderwell. It has 4 relays: one for the AC compressor cluth, one for the fuel pump, and two for the electric fan (high- and low-speed.) The AC is the one that fails the most. You can replace the CCRM by removing the intake air filter box and working through the fenderwell openings. If it gets to difficult you must remove the wheel and splash cover to replace it from the wheel opening." - H-andy Mann
with the engine idling, tap on the ccrm and listen for the clutch to come on. if it comes on, you need to replace the entire ccrm.
If fuel pump is not coming on, check the relay. The relay is incorporated into the CCRM, which is under the hood at the passenger side wheel well. Back-probe pin 5 of the CCRM connector (dark green wire with yellow stripe) using a 12 volt test light or voltmeter. Connect the other test wire to a good engine or chassis ground point. Pin 5 should be hot when the key is turned on. If not, check pins 11 and 12 in the same way. If pin 11 (light blue/orange stripe wire) is not hot, check the 20 amp fuel pump fuse.
If the pump is working, see if there is a schrader valve on the fuel rail on top of the engine where you can check for fuel pressure by depressing the valve stem. Do this carefully with a rag over the valve to prevent squirting fuel on yourself.
If you have fuel pressure, check for spark using the procedure given at the following post: http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines . Please let me know if you have any questions and thanks fopr using FixYa.
You sure the ground wires all reconnected? Check for power at the inertia switch. If it has power,the pump may be bad. Power to the Inertia switch comes through the FP relay, from the fuse. The relay is in a box called the CCRM (constant control relay module) Power from the relay to the switch is Dark Green/ Yellow wire.lF that wire has no power in the crank mode, then I think the CCRM is bad. The CCRM is located behind the coolant reservoir on a bracket. The ground for the CCRM is right front of engine compartment G103, dont really have a picture to tell you where exactly to look. Thanks for the detailed story, a lot of people write " it wont run, whats wrong"
