em2 k swap electrical help (no start)

Hello

I just finished putting together my k24a4 swapped em2 last week and I'm having trouble getting it to crank or even turn over. Along with being unable to get the key out of the ignition without disconnecting the power source (jumper box). I'm using the k tuned adapter harness for the c101 plug on the ep3 engine harness, with a kpro ecu. I have the immobilizer unchecked in the calibration along with the multiplexer being set to normal (I tried disabled as well, no cigar). I can make the car turn over by bypassing the under-dash fusebox (the starter cut relay) but the car sounds like it's not getting fuel or spark. All of these factors lead me to believe that this is something related to the immobilizer or some other security/safety "feature".

Problems:
-Cant get the key out of the ignition without disconnecting battery
-starter not coming on when I key it to start
-if underdash fuse box is bypassed car still doesn't have fuel or spark

Parts:
k24a4 engine
EP3 engine harness
k tuned harness
Kpro v4 (new)
EM2 chassis (auto to manual swapped prior to k swap)

What would cause they key to get stuck in the ignition like that?
Is there maybe a ground or something I should check? a setting in the kpro?
Any help is appreciated I just want to hear it run.

Got the car running!
Mac25 was right, I think it was the auto pedal circuit. I figured it was something related to this originally but when I jumped the starter it still sounded wrong, turns out the fuel pump wasn't plugged in. (don't remember doing that but )
Just bypassed the starter-cut relay in the under-dash fuse box by connecting the black and white wire from the key switch to the black and white wire on the C101 plug.
This means it doesn't need the car in park/the clutch pressed in which I will be fixing later.
