SOURCE: my 93 taurus turns over but no start the CCRM buzzes when the key is on and I have constant power to the coil wire when not cranking changed CCRM no help used too if I hit CCRM it would stop buzzing

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

I have a 93 tempo and it won't start. I've replaced the fuel punp, ignition switch and ignition cylinder. The check engine light doesn't even come on when I turn the key to the on position. Fuel pump...


With out doing any electrical test's , just off the top of my head , I'd say the CCRM - constant control relay module is the culprit ! This module houses the fuel pump relay , PCM relay , cooling fan relay an a couple others as well .It should be checked for battery voltage at a couple of place on the connector for the CCRM . An check the grounds as well . When you turn the ignition key to run it powers up the module , that should be checked for battery voltage also . The module is mounted to the driver side shock tower , in the engine compartment !

I dony have fire comeing out of the ignition module i replaced the igniton still no fire what couls it ge


Check your fuses, Pull coil wire and lay the end 1/2 inch from a good grounded area of the motor. Turn the key and check for an arc from the coil wire to ground. It no spark, might be a coil problem.

Location of cooling fan fuse


The radiator cooling fan on your 1990 Ford Thunderbird Super-Coupe is supplied power via the BLACK, 18 Gauge, fusible link near the battery.
If your cooling fan is not getting any power to operate (and you are certain that the fan motor is in good working order) the most likely cause of you fan not working is a failure in the Constant Control Relay Module (CCRM), which is mounted to the upper radiator support.

I have replaced many of these because the circuit boards inside them like to burn.

HERE IS HOW TO TEST IT:

Check for power at the CCRM on pins 3 and 4 BLACK/ORANGE wires. If there is power there, the fusible link is good. If there is no power at these connectors, repair the fusible link or the circuit between the fusible link and the CCRM.

Then, the Powertrain Control Module (PCM) turns the fan on by grounding the fan relays inside the CCRM at Pins 14 and 17.

So if you have power on the BLACK ORANGE wires, You should be able to manually turn the fan on by grounding Pin 14 (TAN/ORANGE) for fan LOW speed and Pin 17 (GREEN/PURPLE) for fan HIGH speed.

If grounding these wires does not get the power to come on at the fan motor, then the CCRM needs to be replaced.

If this makes the power come on (at the motor connector) but the motor will not run, then you need to replace the fan motor.

If grounding these wires makes the motor run, you have a problem with the engine coolant temperature sensor or the PCM.

It would not hurt to take a look at the engine at night running in the dark to look for arc over or even internal arcing of the coils. The plug wires and boots will reveal themselves readily as will the bleed off arcing that sometimes occur with the coil packs.

Checking alternator output under load would be something to look at also , the coil packs do take a fair amount of current.

It would not hurt to replace the Throttle Postion Sensor, it may not resolve the issue, but it is likely high enough in mileage to warrant it, though as just routine service. Also check the transmision linkage to make sure it is correctly adjusted if you have automatic transmission.

Cooling fans will not turn on 1993 taurus sho


question...is the vehicle over heating and does it only do so at slow speeds or idle?

check your CCRM (constant control relay module) located on the radiator support

check for power on the black/orange wires and good ground on the black/light green

not uncommon for the CCRM to fail

1996 Ford Taurus LX wagon. 3.0L 24v Duratec. Stalled leaving red light then no power at all. Towed home. Starter tests passed at home by manually putting power from B+ to 's' clip on starter. Starter also...


I would look at the positive cable at the battery and at the starter. Pull the cabel off and a continuity test to see if the wire has a internal break if the wire gets even a pinhole it can build corrosion on the inside of the wire and when a current is put through it it seperates (from the resistance and arc from corrosion) causing the wire to seperate internaly.

Hope this will get you started!
