93 4cyl Help!!!!!!!!!!!! My going nuts!!!!

When it dies next time, see if you can check if the fuel system has pressure. Gunk build-up in the tank can block the fuel filter at the pump intake, then fall away after the pump has stopped for a while.

I chaged the pump.....

Problems of that nature tend to be intermittent electrical faults. have you checked the ignition coil? (primary and secondary resistance, hot and cold temperatures, also try tapping on the case to see if that changes the readings)

Yes,..but the tank mayhave a build-up of foreign material which is blocking the pump inlet occasionaly. Then after the car has stopped for a while, the blockage clears as the gunk falls away from the inlet due no suction (ie, pump is off).

Your car has OBD-I system, a scanner would be a great asset. It could be as simple as a clogged air filter or faulty MAF sensor. Check autoxray.com (EZ-Scan 3000), obdii.com, autotap.com and ebay for scanners, not code readers.

Your car's OBD ('93 4 cyl.) doesnt' require a scanner. You only need to use a jumper wire (paper clip) and can read the codes directly.

"no bad diagnostics on check....." does this mean no codes to read? Scanners do read ECT temperature, Air flow, Short/Long Term Fuel Trim, Advanced Timing, O2 Sensor voltages, RPM,...

as

directly.

That's what it was, I found a carbon trail on the coil. Must had broke down after a warm up....THANK YOU!!!!! The car run like a ball o fire now!!!!
