hey guys, this is a 5.3L IV gen, i'm rebuilding it, just got confused about crank sensor and cam gear, crank has 24 tooth reluctor wheel (black sensor) with 1x cam sprocket, into a colorado 2004, using 2002 truck pcm, i'm almost sure cam sprocket is correct with this setup, when i tried to fire it up, it just throws explosions as it were out of time, am i using correct cam sprocket? should i change it for 4x one?

The 1x is for the 24x crank. As long as the ecu matches the engine and the cam is degreed correctly you should be fine

I still have some doubts about pcm just found it is a 411 pcm (12200411)

im using painless wire harness 60217, made a change in cam sensor conector with 2 cables just inverted them to make sensor work, i guess something may be wrong around there...
engine and cam are well on time, followed harness instructions as mentioned, everything is right i guess...
