1990 Pontiac Grand Prix Fuel Problem

Hello, are there any codes? With the engine cranking, do you have spark at the plugs? No spark or injector pulse, I'd look for an rpm signal.

Your obd1, you should be able to check codes yourself. Use a jumper wire between terminals A & B of the datalink connector, turn the key to on, no crank, the check engine lite starts flashing, you count the flashes to get the codes.
