2000 chevy silverado 5.3 crank no start

Additional_Put_2374B to Mechanic Advice@gearhead.townEnglish · 10 months ago

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?

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