96 240sx will Crank but no start after Auto to Manual swap.

[overseaz]

Im from sacramento and I Just did the swap in my 96 s14 following the writeup at: auto-to-manual-writeup-5-speed-conversion-t181139.html

My question is, now that it's done all electrical has been double checked, it cranks but won't start. I get spark and can hear the fuel prime. I only pulled one code from the auto ecu which was P1605 A/T Diagnostics communication line. Which of course is to be expected since its been removed. I swapped over from the 96 S14 auto ecu to the 95 S14 manual ecu and get no codes but it still cranks and fails to start. Everything sounds normal but it won't fire up. I get the same result with both ecu's.

Any ideas or suggestions on what I've maybe missed?
Manual transmission is from a 97 kouki. I used my auto harness since I didn't have a manual harness at the time.

Also, did everyone that used the auto harness cut the sensor plugs off and just use butt splices? I used quick taps for now in case I find a manual harness down the road, I can still use my sensors with their plugs.

When I did the 5 speed swap on the 180 I had to jump a relay up behind the headlight. It was a neutral safety switch of some kind.

Yeah i already looped that to itself... the top connector next to the fuse block. That was easy.
Tho that also wasn't the issue. We got it started, turns out the wrong wire was cut on the ECU.
there were two wires on the ECU. one Red/Black and one Black/Red.
apparently in the write up when it said cut such and such wire its the second row 3 wires over,
which was Black/Red. the one that should have been cut was Red/Black i guess.

I will look into this more just to be clear, but at least its running again!
