    Default po 336

    I have a random no start, and complete no run situationin a 06 lbz .I have a code 336. Upon the initial test of the circuit, I have an open low reference signal,ground, I am also open between frame and connector. Is it ok to connect the ground directly to the engine for a test? or do I need to trace the wire down, TIa
