Q: Car will not start

asked by on October 05, 2016

I have rebuilt the engine, marked and assembled everything correctly, installed new injectors. There's great spray pattern and great spark, is there possibly a sensor that will keep the engine from starting, or is there one attached to the front clip (still off the car) that would have the same effect, and last but not least could I have the crank 180 out?

My car has 184000 miles.
My car has a manual transmission.
