Need three things for gas engines fuel, fire, vaccum. Do you have fuel, fire, and vaccum could be injectors should register 1.8 each could be fuel filter, plugged, could be bad vaccum broke, cracked or missing. if it only runs for a second do you lose fire, or fuel?? If you lose neither could be vaccum.

CHECK RESISTOR TO COIL FOR OPEN CIRCUIT. KEY IN START POSITION BYPASSES RESISTOR, JUMPER WIRE ACROSS RESISTOR WILL CLOSE CIRCUIT ALLOWING MOTOR TO RUN FOR TEMPORARY FIX. THIS BEING THE CASE FOR MANY CARS
