rb20det wont start!

[crxcess]

Well I got the motor in ok, everything is plugged in.I got spark, and fuel pressure. it just wont start. also im having to start the car by taking the starter wire (black/white). when i plug it in to the other wire its wanting to start without the key. I followed the 8 step to starting an rb motor but no go!

Nice more pics??? so the wiring writeup is good right? any sugguests for wiring also is it the first time you wired an engine?

Yes its the first time I wired a nissan engine... I have done hondas before. Everything worked fine, I had a few questions. one was step 7) what white wire? answer: 8 gauge wire( real thick one inside of the loom) . I am also having problems with the starter wires, I think its because my car was an automatic. problem is I cant connect the wire because it activates the starter without ignition key input. It could also be because I didnt use the Ka positive battery harness. Branden (wiring write up author)was a Big help! Also you have to hook up the piping or it wont start!

I JUST USED THE KA LOWER HARNESS AND SPLICED THE RB PLUGS ONTO IT. THERE WERE A FEW OTHER THINGS THAT I CAN'T THINK OF OFF THE TOP OF MY HEAD.

ONE THING IS IF YOU DON'T HAVE THE MAF HOOKED UP IT WILL NOT START AND IDLE.

Got a question?My car was an automatic... if I jumper the auto trans wires I can use the key to start the car? I retained the rb trans harness, only thing I kept was the speed sensor. I have read that I need to jumper the wires on the transmission harness? Is it possible to just jumper the wires in the console area where the shifter is? If so then which ones?
