unfortunately their is no code reader for this vehicle that I'm aware of. I gave my repair manual away when I sold my GEO, but all of the terminals on the diagnostic port are to perform a certian function, like turning on the fuel pump, engaging the AC compressor, hooking up a tach... Not for retrieveing diagnostic codes.

I have the repair manual. With that will it help? I had to replace the starter thing (also is the cap and rotor) all one piece. Replaced plugs and wires too. It was a used from a pull part place. and I need to have it diagnostic. She has no guts now and she spits putters and is costing lots in gas. What can I do?
