HELP LQ4 swap wont start A little background. Engine is a 2000 LQ4 with ls1 intake and injectors swapped into my 68 Nova. Shock harness modified to run stand alone with LT1swap.com instructions. PCM is from a 2002 5.3 Yukon. EGR, rear O2 sensors, AC, EVAP, everything has been deleted. I tried to start it the other day and it cranks and fires up but then dies immediately. When i try to restart it, it sounds like its trying to start but wont. Ive verified power to all the injectors, continuity from the injectors to the PCM, 58psi at the rails, verified spark at all cylinders. No codes except for evap system which is removed. I havent sent the PCM to get reprogrammed yet but I assumed it would atleast start and run with a rough idle. Im at a loss. Could the PCM not being reprogrammed yet cause it to not run? VATS?
