I have spark I have fuel, timing is dead on correct, checked camshaft sprocket pins and are still correct position. New plugs, coil pack, cam sensor and crank sensor. No codes. PCM programmed from Chrysler. Backfires through intake after cranking awhile. Will not start at all. Verified crank and camshaft signals. Even tried alternate fuel. All with the same results. Please help.

Good evening,

I would start by checking the compression to be sure there is no internal issue inside the engine.

Beyond, that, I would unbolt the front pipe from the manifold and try starting it in case the catalytic converter is clogged.
