We have a Nissan powered Tcm lift. no power to the lockoff. The relay that controls that circuit is getting power from the ECM.
But the circuit is not completed to GRD.?I have checked the relays, wiring ,lpg driver.???this truck had a dead battery at the time of failure, but I do not know which came first. the no start or the dead battery. It now cranks good and I have check all physical grds. Any help or leads would be appreciated Ray
