So I picked up my FD with a blown motor and an automatic, I picked up JDM motor and 5 speed with harness and ECU. Switched out motor put in 5 speed with the 5 speed harness. I had to splice the auto plugs on the 5 speed harness to get stuff to hook it up to the dash wires.
Tried starting and it won't fire. I am getting spark, fuel pump turns on and I have fuel pressure, I get power to the ecu where it needs, tested crank angle sensors and they seem to do what they need to.
I am a bit stumped, anything else I should look at?

Thanks

Cheers
