Might be some other features if in a car with impact sensors and such, cannot say for sure. The most basic feed from the ecm is the fuel pump would be energized for a prime cycle. The ecm would also shut off the fuel pump if the engine is not running. __________________ Richard 1972 K10 Custom Deluxe SWB Fleetside My build https://67-72chevytrucks.com/vboard/...d.php?t=800746
