Just gonna put this out there. Can you use punctuation so I don’t run out of breath reading that run on paragraph?

It would also be nice if we knew the year, what motor, trans, and if any modifications have been done.

My bad, I didn’t realise it was like that.

It is a 94 gt with a 5.0 and 5speed trans. I have had to add a aftermarket temp gauge; due to the fact that the one in the in instrument cluster wasn’t working.

Let's start at the very top then...


Pull codes.

How’s the wiring look to your aftermarket sensor? No shorts or frayed wires?

I believe that it could be the constant control relay module

Cheap scanner and does the job:

Amazon.com

Buy this and pull codes. This will help narrow things down so you are not shot gunning parts.

The 94-95 5.0 blocks have two temperature sensors - one that feeds the gauge in the dash (the CTS), and one that feeds the engine computer (the ECT). If the ECT has failed and is sending random values to the computer, the fan won't kick on. Found that one out the hard way. A higher-end code reader an show PIDs in the computer, which includes the ECT values. I'm sure there's a way to test the ECT using a voltmeter, but I don't know how nor what values are appropriate.

I believe that if the CCRM had failed, the fan wouldn't turn on at all. Since the fan does turn on when you unplug the temp sensor, the CCRM is likely fine. You can also run the KOEO and KOER tests, which test if the fan runs. You'll hear it turn on for a bit during the tests.
