Re: Intermittent No Start - 5.3 L59 swap - Injectors Not Firing
Maybe check the grounds. Engine to chassis, battery to chassis and ecm to chassis. Would also check battery cables.

Done. If anything, I have more ground paths than the factory. ECM/TAC module/engine grounds are directly tied to the chassis and the battery; they do not have to rely on the chassis alone.
