06 lbz no start
 

I was driving my truck 06 lbz and it started to run bad I stopped and it went back to normal so figured it was just a hiccup started to drive agin went about a mile and a half and started to run bad agin then died got a code for crank position sensor came up replaced sensor and still no change I tried about 3 other sensors and tested the last one I put in to make sure it worked checked fuel pressure that was good checked compression had about 300psi on all cylinders pulled the glow plugs and had fuel misting so I believe injectors are good I pulled the crank position sensor out and put my finger in and the gear feels tight and scoped it and it looked good I even pulled a known good ecm out of another truck and that ended up good everything I’ve tested turned out to be good I ran out of things to check so I’m hoping someone has some in site to help out all help will be greatly appreciate
