Car tries to start in accessories
 

out of the blue my car decides to start when I turn the key in accessories. What could this be I have an rx7 fd it was starting fine the other day.

Bad ignition switch.

ive done a wire tuck could i have possibly have wires that are crossed or something?

Only if you crossed the starter wire with an accessory wire. Unlikely, but possible.

do you know what other ignition switch is compatible with the FD as where i am from there is not alot of rx7s here and i cant seem to find any second hand online either

If the problem is a wiring one you would think it would be occurring very near the steering wheel column.
