Sr20 stalls and then wont start

[89_SR20]

So I started having a problem where under normal loads when the car is at operating temperatures the car would die at lights, highway or just idling in my driveway. I have checked body grounds. used throttle body cleaner and fuel injector cleaner, replaced my sparkplugs and had coils/fpr and injectors tested. Replaced the fuel filter and the fuel pump itself with a 350lph pump but it just keeps dying. Any help. Am I missing a wire ground out somewhere? Temp or O2 sensor?

sounds like a coolant temp sensor problem.

If it were the sensor would it be throwing a code? Its a 91 so I have to pull it from the ECU but I get Error Code 55, which to my understanding means no problems found

Have you checked your MAF?

Yeah MAF was the first thing I checked initially even when unplugging it the car will die and not restart

It died again after replacing the CTS so I got angry and started pulling on wires ( I know bad idea) but it solved the problem the fuse box wiring is screwed completely the tape and shrink wrap is off and exposed wiring all over the place. I didn't notice it before but thank you all for the help!

coolant temp sensor!

lack of air. open up the aicv.
If that fixes it, check timing, adjust blah blah blah!
