2000 Jeep Xj Cherokee P0340, P1391

No start, will occasionally starts briefly with tach going crazy showing like 5000 rpm and not idle, but mostly just acts totally out of time. Emptied out the parts cannon before getting a Hantek 1008C Friday and getting this reading of cam and crank. Included is a good wave for reference. Yeah I know I needed to flip my waves. Whoops...

Crank sensor is reading 20 pulses per cylinder instead of the 4 it should be. Everything seems fine hardware wise, thoughts?

So I've narrowed this down as the whole problem with the no-start. I have fuel and spark, even though injectors are firing 5x too often resulting from the weird ckp signal. The p0340 and p1391 are triggered because the ecu thinks the cam sensor is only signaling every 5th rev.

I'm not picking up flexplate teeth because I have a clear window between cylinders. If it was faulty wiring wouldn't it look way more erratic?

I have 5v feed and 5v coming from the ecu ckp signal pin when ckp signal is depinned from sensor plug, stays on solid while cranking so I'm stumped as to what it could be. What could cause a crank sensor (multiple crank sensors more like) to read 5x too many windows?

Air gap is incorrect. Did you leave the cardboard spacer in place when you installed the sensor? That spacer gives the proper air gap. It will be wiped off on first start up.
