so here's the story about a month ago my tach quit working when i was driving my truck. when i shut off the motor it wouldn't start again so i checked my fuel pressure and realized my fass wasn't working got that all figured out and got everything back together. i now have a constant 14 psi of fuel pressure from my fass. my brother and i bled the injectors tonight and finally got it to fire. my tach still doesn't work and i replaced my crankshaft position sensor(the one behind the starter) and my computer is still throwing the code for it. the code from my smarty is.
0366 crankshaft position sensor performance.

what is my problem and how do i fix it?

thanks
Austin

 

The truck will not start on its own. It will only crank, gave it a shot of starter fluid and it fired right up. Check engine light comes on and the tach doesn't work. Revs and runs fine.
