V35 vq25det + z33 swap help please

Manual conversion on vq25det (No Spark) need help
Hi all
have just finished transplanting a vq25det into a v35. We have used a z33 6 speed manual gearbox and clutch to bolt it all together. everything is in the car at this point and for some reason we are not getting any spark.
We are running the ecu bcm ignition barrel and key and full loom from the donor car an m35
I read that the starter motor relay needs to be bypassed so am using a trigger wire and button to turn the motor over while ignition is set to 'ON' (this will be relayed off ignition circuit later)
The v35 has been converted from returnless fuel to return setup to suit the new motor 'vq25det'. Fuel pump is currently relayed triggered by 12v ON circuit so we definitely have fuel reaching the rail.
The idea was to get the car running on the standard ecu before going haltech and front mount turbo in future. We have the matching ecu from this motor so auto turbo stagea ecu. currently the auto transmission error light flashes with the auto gearbox ecu unplugged and it stays solid if the gearbox ecu is plugged in while trying to start the vehicle. currently the plugs that would have gone to gearbox are not plugged into anything as the manual has almost no sensors.
My belief is that the car cannot tell if it is in P when trying to start the engine so it is stoping the motor starting through no spark even though we are forcing the starter motor on.
Any thoughts on putting a resistor in the right place to trick the ecu into thinking it is in Park so the motor will start?
the only other thing i can think off is the immobilizer due to a different ecu but its still the same key and lock barrel?
Any advice would be great.
Thanks all

You can probably cheat your way through it by downloading a copy of the Consult II software and loading it onto a laptop, not that I would ever recommend using illegal computer software but I'm sure you can find a "legitimate" way of doing this using google >.>

You can also get ahold of Symore4 to see if he can help, an Uprev cable can eliminate NATS interlocks and you will eventually need to tune anyways so... Uprev cable...
I'm not sure about the park interlock bypass, would need to see a wiring schematic for the donor vehicle but I don't think it needs a resistor unless there was an EOLR built into the transmission, usually it's just a normally open switch in the transmission so you would just jumper across the correct pins in the harness.
