Hey Mr Jeebs, curious how you determined it was a dirty signal. Did you just swap it out for an OEM mitsu part and it worked okay after that? Did yours sound like my video at all when trying to start?

This monty has been sitting in my yard for a while, I just keep wanting to fix it not quite ready to give up on her yet. Went thru all the injector wiring today and found no faults, so crank sensor is next on the list.
