Could be one of the fan switches. Locate switch (brass plug in block, 1 on each side), turn ignition switch to "on". Leave on and unplug wire from fan switch, and touch to metal ground. If fan comes on, you have bad switch. Try this on both of them good luck.

I ran a wire to a switch and to the battery but could only get one of the fans to work but it cools it down just fine.
It was getting well over 226 .
Im putting a 180 degree thermostat in it tonite,ill just run the one fan until i can get more time to look at it.
Thanks for all your help

Ok I found that out thanks,but now im in deeper **** I think.
I drained water out of the rad and put rags all around the thermostat and loosened it up water began coming out so I tightened it back up and checked to see if it would fire cause I was afraid of that optispark.
And it turns over but dont fire !
Will it dry out or am I screwed or could it be something else?

There are no fan switches in a '92.
both fans are controlled by the ECM alone which gets it's temp signal from the CTS.
(If CTS was faulty ,he would have more than fan problems.)
And when a fan switch is fitted ,as in pre '90 models it is in the head where coolant is hottest , not in the block.
The sensor in the block is the knock sensor.

It is not a faulty "temp "sensor.
This is an integral part of engine operation, fuel management, etc. It is what the car uses to control all functions via the PCM as well as turn on cooling fans and
If the temp sensor (CTS ) was faulty he would be having engine operation problems.

He obviously has no idea were the sensors are located in his own car or their mode of operation, let alone a '92

Yeah I know....anyway i got that all sorted out thanks.
But however now i can't get it to start and it was running fine yesterday.
I put a new coil on it just because advance didn' have an ICM but that didn't help.
I had my son spray starting fluid in the throttle body as I turned it over and it almost started for a sec till the hood fell on his head! lol hes ok.
But does that tell me it's the fuel pump or something else maybe an unplugged wire or a fuse or relay?
