I'm troubleshooting a no start issue. I've swapped the ignitier as the shade tree resistance test from miata.net show it out of spec. One side of the coil primary is out of spec by about an ohm but the other side specs. No spark on either. Rather than throwing more parts at I've started step by step. It's looking like the ECU. I'd removed the instrument cluster so I had to go get it from the boneyard and hook it up to see the MIL. No MIL but power to the ECU. I'm checking for grounds or shorts, hoping I left one off. I'd rather not put any more money into it as I just want it to start and drive. And it doesn't even have to run that well.
Rather than counting blinking lights I have an opportunity for a pro grade scanner/recorder at a screaming pawn shop deal. It's the current version of software for that tool family so I'd use it on the street cars but if I could use it with the speced adapter for a Mazda ODB1 port. The software manual says it will work on an ODB1 Miata for basic codes.
Is anyone using any of the Snap On diagnostic scanners/recorders for Miata ODB1?
