I’ve been fighting an issue with this project truck, no spark, I have swapped bcm, pcm, crank, cam sensor and even bypassed security system with hp tuners. The motor is grounded well and the neutral safety switch seems to register fine on the cluster. Any insight?

How’s the fuel pressure?

Also did you disable the codes related to the security system when you disabled vats? That had me stumped for awhile, I can’t remember but I think there’s 3 codes P16xxx

  Would fuel pressure affect spark? Even with bad security it should fire up and die within a few seconds.
