You have a 2.2L engine?I would be looking at the code P0202 that's injector control circuit.I would be looking. At the injector harness to the number 2 Injector. Most likely there is a problem with the wires to it. Let me know what you find. Make sure you have power with the key in the run position to one of the wires and the other wire to the number 2 injector should have a flashing ground while cranking.
