2004 GMC Sierra 2500 HD swapped in a ATK HP109. Stock manifold, stock injectors. got it to initially start and run with this tune when it was about 80 degrees outside. Now its about 40 degrees outside went out to continue idle tuning it and wouldn't start. pedal to the floor flood mode can hear engine firing out of exhaust. I've tried adjusting so much and nothing has helped start it. will upload the tune it initially ran off of and a scan of the current crank no start as well as the one log I took when it did run. Any help is appreciated.
