Car died on the road, diagnosing a no-spark scenario. Plus MYSTERY PART!

[karbon]

Here's how it started:
Awhile back I posted a thread about my coil pack harness getting wound around my axle and getting yanked out. I repaired the harness and the car drove fine since then, except when I got over 10# of boost, the car would bog like crazy and I got no power. Didn't feel like fuel cut. It just had no power until I let off the gas and applied it again. The car was drivable if I just went easy on it and was a go-between until I had the time to fix the problem.

Fast forward to earlier last week. I was driving up a hill and gave it some gas, boost went up, car bogged but this time it just shut off. I got it towed home and started poking around. I discover I have no spark.

I test my coil pack: Primary coil resistance is a little high, but not much over spec. I tested the coil pack after the harness incident and had the same numbers from before when the car was running.

I test my wires: resistance is in spec.

I test my Power Transistor: everything working fine.

So I take off my timing belt covers so I visually inspect the cam and crank angle sensor and HEY there's a shredded balance shaft belt in there! I check my timing marks: everything's still lined up. I'm a lucky son-of-a-bi***. However, when I undid the lower cover, a piece of metal came out that looks like it was important, shown below.

I have no idea what this is. If it's a piece of my crank angle sensor, that would explain the no spark situation, right?

I back-probed the plugs for both the cam and crank angle sensor. I'm getting no voltage on the red wire in either. From what I understand I should be getting 5v. The grounds (black wire) on both are fine. I think "hey maybe it's my ECU". I swap in another one and still have the same problem. Also I should mention the trigger plate on the crank angle sensor wasn't bent or deformed by the BS-belt.

Is there anything else I can check? Am I checking the crank/cam angle sensors incorrectly? Surely I can't get any signal voltage if I'm not getting any supply voltage. It's unlikely both sensors are at fault, but the ECU isn't to blame. What the hell is that mystery part?

If the trigger wheel was deformed it could have very easily taken out the crank angle sensor and that kind of looks like the remnants of one. Could you not visually inspect it? Seems like you were already down there so you should be able to easily check it out.

Yeah I kinda ran out of daylight today and will be checking some more things out as the week progresses. I wanted to get some input on what I've inspected so far so I hopefully have some fresh ideas when I get back to work. The next course of action is going to be unbolting the crank angle sensor and getting a closer look.
