no fire,a bit lost....

i had the same problem.turns out it was the ground from the starter relay. the neutral reverse on the transmission has nothing to do with it. it does not have to be hooked up to start and run.my ground LOOKED grounded but it was not. take the ground off and run a whole new wire to the body and see it that works.i was also able to jump it off the starter relay. i dont know if this is your exact problem,but a mere suggestion.

Are you sure you typed all this correctly?

The "ground" on the starter relay has nothing to do with the engine ignition, and on either stick cars with clutch safety, or auto cars, there IS NO "ground" on the starter relay.

The neutral / reverse switch HAS to be hooked up to crank the engine with the key.. If you crank the engine by jumpering the relay, the ignition puts out a poor spark because the coil resistor bypass circuit (IGN2) is not active.
