Right, just putting the 14s engine and box in here and wiring it all up. But the immobiliser is DOING ITS JOB and car wont start.

How do i bypass the NATS??

If you have a full service manual try running I cable from the signal wire on the starter loom to the signal wire at the ignition, I think the cable is black/yellow strip this might bypass the immobiliser, hard to know when your not looking at something

run a wire from the live on the fuel pump to the ignition? when i put an aftermarket ecu in my old civic coupe thats what i had to do to bypass the imobiliser. just be careful not to leave the ignition on when your sitting up coz it will drain the battery coz the pump will be goin constant

Its Waynes old S14 that we're doing. You already done it but put it into a new shell and plugged everything in and the EML wont come on and fuel pump isnt running.I rang Brian Wilton and he said it will be the NATS in the new shell.

Could you PM me how to get it sorted?

does the NATS just disable the fuel pump? Its just a competition car so if thats all it does i could just wire it to a switch and relay...

will this work on my bmw , i have it on button start , i still needed the key in the ignition to start tho , one day i went out and the car wouldnt start , it was because the chip in key was gone , will this bypass the imobiliser in bmw's aswell?
