Default Lq4 no spark but power to coils.

I have an lq4 that does not spark, battery is good, good grounds, new tps, new crank position sensor, I have 12v to the crank sensor, 12v to injectors, 12v to coil packs, all the fuses and main relays are good, next on the list is the cam position sensor.

I just fixed an issue similar to this yesterday. One wire on my crank sensor pigtail was loose from the connector. Since i'm speed density and not using a MAF, i cut the pigtail off it and rewired it. Crunk right up. You have hp tuners?

Coils will fire without a cam sensor signal. Does a scan tool show rpm when cranking?
