Anyone have a cam crank relationship waveform of this engine? It pops through the intake manifold when trying to start it but if I unhook cam sensor on passenger side head it starts runs pretty good. Thinking maybe the reluctor slipped on passenger cam because relative compression test comes up all equal percentage on ford ids.

Found that this morning. I think my timing is way off but runs good with the right cam sensor unplugged. My traces are labeled and laid out the same as the known good.

:huh: It looks like you have Yellow and Green on the same Cam.

When bank 1 Cam signal has 3 "fingers", Bank 2 Cam signal should have 2 "fingers".

Not on the same cam sensor back probed at sensors at each cylinder head.
