Thanks for the add! Picked up my first Colorado two weeks ago it’s a 2008 2.9L 5 speed manual bought it as a no start, was told it only needed a starter although I knew It wouldn’t need just that. I was also told the camshaft sensor was replaced but still wouldn’t run. Since purchase I have since then put a starter, purge valve, ignition switch, and a knock sensor pigtail. Truck still won’t crank. Any ideas of what it might be?!? Also tried to plug up a scanner but it wouldn’t read anything and just say error.

Any help would be appreciated I’ve been looking everywhere for an answer like fb groups and forums and no one seems to know. Any response would be greatly appreciated I can provide a video of exactly what’s going on also if my wording doesn’t help. Someone please help!!!
