in you pic, look at the wires on the top left side of the dizzy. there are about 4 connectors over there. make sure they arn't loose. you can also put some di-electric grease on the connectors, to resist corrosion. those connectors cause 99% of dizzy problems. Also you have peak-hold injectors if you have a resistor box. there is no internal difference between obd2 and obd1 dizzy's. only the plugs are different.
