So I have a 1997 Miata with a 2001 motor running on Megasquirt 3 pro. Already did a CAS delete and it was running great. Just installed a turbo on it. Tried cranking it, no rpm. adjusted the crank position sensor. got intermittent signal and then nothing. Replaced the Crank sensor. still no signal. I used a multimeter to check the sensor and it doesn't seem to be reading the crank wheel at all but I could be testing it wrong. I don't know. I looked at some threads saying it might be a shielded ground. Or I think it could also be the Cam pos sensor. But I honestly just don't know at this point. Any tips? for testing the sensor, or checking anything else that I could be missing?

Edit: I have now changed the Cam pos sensor as well. still no rpm reading.
