Ok, I cant get this car started heres whats going on

The motor/car setup
95 civic hatch with 94 Si trans and Integra d16a1 (early ZC) motor.I am using my Civic' ecu and fuel system.

The problem:

I put the motor in and checked timing many times, it has to be correct. I went to start it and it wanted to go but just wouldnt start. Then for some odd reason I decided to pull the cam pos. sensor. The car started, however, it ran like poop. the idle was high and if you hit the throttle, about half way in it would almost stall. you plug the sensor back in and the car wont start again. It has the little cam posistion sensor on the exuast cam kind of like a B 20.

I need help its almost been a week of me trying to get it right, and I am starting to run out of ideas.

thanks,

Nick
