Modelle, Try unplugging the connector to the fuel cutoff solenoid. You should also try to apply +12 volts on the solenoid and verify that it is not stuck in the cutoff position. If the microswitch is shorted this solenoid will stop fuel delivery. The car can be driven without the connector plugged into the solenoid, and if the pump is setup correctly, you will hardly notice, as the Spica has a redundant mechanical fuel shutoff.
