'78 302 the car starts right up for about a second then shuts right off. Drove the car today, drove fine car sat for couple hours, went to park in garage and it would start up then shut off. Took the fuel line off and cranked it a couple times, its getting fuel, change fuel filter, checked spark plugs and the gaps, it has new wires, new coil, new roter and new module. Took the module off and put old one back on, still doing same thing and its getting spark. What can it be? thanks
