you are not getting any power to the starter from the ignition switch, make sure that you connected that right and check for blown fuses.

BP engine fuse is 15amp and not 10amp like the B6.

also if you have a 94+ you have to swap 2 wires, otherwise that'd be blowing your engine fuse if not swapped.

i swapped the 2 wires over . which ones the engine fuse and ho do i know if its blown

i red in a post you need to use the origianl mx3 ecu not the gtx is that right

i just read if there is an immobiliser on the car and its intergated into the standard ecu it wont start with the new ecu
