Question about 1992 Pontiac Sunbird
You need to drive it, and when it stalls and won't start, then is when you need to check to see what you are loosing. Spark? fuel pump? or injector signal?
Spark, you will need to hook up a spark tester to one of the plug wires and have someone turn it over.
fuel pump, leave the key off for a minute, and then turn it to "run" and see if you hear the pump. (listen at the gas cap, as it should cycle for a second or two)
Injector signal, for this you need a "noid" tester that plugs in where your harness meets the injector, and have someone turn over the engine with the key, and you should see a blinking light, meaning that your computer is telling the injectors to fire.
