1991 SC
Default My 91 SC died please help!!

I'm new to this so i'll say sorry in advance.Here's what happened, my car was running fine 2 weeks ago. I went to the store when I came back out it started right up and then immediately died as if I turned the ignition back off.
Here's what i've done so far. Checked for spark at coil packs good. So I've eliminated the CPS.
Replaced the ECTS. The old one was broken, but no help.
Replaced spark plugs.
Cleaned Throttlebody and EGR. No help.
Changed Fuel Filter, performed Fuel Pressure check, had 46 PSI w/key on engine off (since it will not start).
I've checked every fuse and relay and Fuel Pump Does operate for 2-3 seconds after turning the key on. Also I used a jumper wire to keep the fuel pump running and when it reaches 46 PSI I can hear it going through the fuel return line back to the gas tank.
It will run on starting fluid, So I checked FUEL INJECTORS all have 12V to them and used a test light to determine that the PCM is pulsing the injectors.
So i'm at a total loss what to do next any help would be very much appreciated. THANKS in advance

REWARD EXCELLENCE!
