Hello all, My son's girlfriend drives a 91 with 160k+ miles which I have had the pleasure of fixing a few times. Once after a left rear colision which required a complete left rear, junk yard suspension, basic tune up and fixing a light switch problem. Nothing very technical.
Now I'm faced with something beyond my basic mechanical knowledge. The car dead stalls, OFTEN. The problem began suddenly yesteday for no apparent reason. Usually it completely dies as though the ignition was turned off of as if the injectors competely stopped, well .. injecting. Matters not if it ideling or not. It starts right back up but will fail again within minutes. I've looked for ways to extract ecu codes but don't think I'm doing something right? All I can get is the 1,2,3,4,5 codes which I assume are the ecu running some sort of self check.
I'm confident this car has many codes stored considering its past. If someone could please explain the process or point me in the right direction I would very much appreciate it.
Thanks,
Chip

thank you for the quick response.

I turned on the key. (no lights on ecu), Turned screw clockwise to stop, lights begin to flash, again what appears to be a 1,2,3,4,5 sequence, turn the screw back counter clockwise, leds go off and remain off?
