I was driving my car listed above I put it into the manual gear selector
mode and was shifting up through the gears while accelerating when the engine shut off. The timing belt had broke. Removed the covers to replace it and the belt was in 2 pieces and mangled near the crankshaft sprocket. Removed old belt. Replaced water pump and pulleys and belt. Reset timing, did 2 rotations on the crank with a breaker bar and the timing marks still lined up. Put it all back together and the car still just cranks no start. Did a compression test and all 3 front cylinders have about 120 PSI compression and all 3 rear cylinders have about 150 PSI. Can hear fuel pump kick on and disconnected the line at the fuel rail and it will spit gas out while cranking the motor. Have not tested fuel pressure however I do not believe I am getting spark at the spark plugs. Could this be cam or crank sensor problem even though its not throwing any codes? Is timing a tooth off because the front head is 25 PSI lower than the rear head? Am I testing the spark wrong? Need help please. Have attached a video of my mess.

Hello, I'm Danny.

It's possible the timing belt when it broke did damage to the crankshaft position sensor by looking at your video. Here is a tutorial showing how to replace a crankshaft position sensor and wiring testing:

I would check the crankshaft sensor wiring to see if the broken belt damaged the harness. I've attached three replacement step pictures below for the sensor. Let us know what you find. Hope this helps and thanks for using 2CarPros.
