Hey I'm in need of a bit of help. I've got a GM e37 pcm with a LAP 2.2 engine and trying to set it up for stand alone. I've got all my pink and black wires laid out to go to switched power, red wire laid out for constant and all my grounds laid out to the engine block and back to the negative. I've disabled vats with hp tuners and have no codes other than cooling fan codes due to not being hooked up yet. I have crank and cam signal. I can't get injector pulse for the life of me and was wondering if I'm missing something that I do need that I don't currently have in my wiring harness, or if anybody has had a similar issue. Any help would be greatly appreciated!

Hi Conner, can you post your tune file and a log of it cranking maybe we can see something in it that gives a clue to wat is happening

Got it. Had to turn off starter fault checks too. Works fine now. Thanks.
