S14 will not start

[jmotley]

I've got an s14 that I've done a swap where I took the motor, trans, harness, and ecu out of an automatic car and put the motor, harness, and ecu with the car's original manual transmission. I used the lower harness that was in the car and pulled the motor harness because the previous owner fucked it all up.

I've got it all in the car and plugged up right as far as I can tell but I get no fire and the fuel pump doesn't prime.. its open header right now too with no o2 sensor in the header (didn't have one its an aftermarket header). So any ideas or steps I could take to figure out what is going on?
as a warning its my first swap with a nissan so bear with me...
