82 Imp EFI won't start/run



Just a shot in the dark. My grandfather had a dodge pickup(68) that would
start, but as soon as the key was released from cranking, it would die. It
turned out to be a bad ballast resistor. I don't know if 82's run with a
ballast resistor in the ignition or not, but if they do, its an easy check.
