NO Start So I have 05 GMC Envoy that I did a LS sawp in. Used a LM4 from a 04 trailblazer, a 2003 Silverado harness and ECM. Changed the cam sensor to the front timing cover. ECM has not been tuned or VATS deleted. Should run for several seconds from what I hear.
Have fuel pressure, spark but no injector pulse. I do have voltage to the injectors, but measure voltage on both sides of the injector harness with injector unplugged. The tach doesnt move either. Cant get a connection to the datalink connector. Had the same issue with factory setup on the Envoy. Have three grounds total on the engine.
Thanks in advance!!
