Diesel Bombers - Truck shutdown and won't restart

I was at the drag strip a couple of weeks ago, and when I launched the truck just shutdown right outside the lights. Gave me a P0335 code (crankshaft position sensor) And it will not start. I've tried a new ECM and a new sensor, the low reference voltage is supposed to be .02v and I'm getting 1.5v on the wire. I'm all out of ideas, I can't find an open or short in the wire anywhere. Any ideas? I don't believe the crank is broken because the engine will turnover by hand same speed front or back, and nothing slips, the oil was clean and metal free also. Thanks guys, let me know if you have any ideas, I'm getting frustrated.
