Hi, I was asked to look at a '91 Chevy Cavalier RS today. Is has the 3.1 liter v6 engine. It ran fine when I drove it home, but when my wife started it to move it, the car died as it was idling. No indication of a poor running engine, it just stopped like she turned the car off. Fuel pressure is 43 PSI when the fuel pump comes on, spark is a nice healthy bluish white color, oil pressure goes up to about 40ish when the engine is cranked, the tachometer registers a few hundred rpm while cranking, and each of the three coils ohm out about the same. I'm not getting an injector pulse. I put a stethoscope to the one injector I can get too, and listened to it while the car is turned over. I plan on measuring voltage to the injector wires with the ignition key on, and TPS voltage. What else can I check?
