trying to determine if i need a new ecu. i have 9 volts from ecu to trigger in distributor and it will start, but voltage stops when it does start. you can keep it running with carb cleaner. when cranking it has alternating volts (1-7) going to ecu. also when cranking it has (1-4) volts to inj from ecu. 79 eldo has 5.7 thank you, tom huff
