car still won't start 700 1991

I have a '91 turbo that i pulled into the garage, and now it won't start at all. I have checked the spark plugs (replaced), the distributor, the fuel pump and all her relays, changed the starter, ran the OBD....came up with a bad RPM sensor...and I am getting ready to change that next. It has spark, fuel, cranks....so I am praying this is it. I would appreciate any help though on something I may have missed. Something tells me it could still be a bad coil....any suggestions on how to test it though?

    When it cranks, does the tach needle bounce? That'll tell you if the rpm sensor is working if it's bosch - maybe the same with regina, I'm not sure.

    As for testing the coil, I would say crank the car with the coil to distributor wire off and shorting to somewhere on the engine. IT MIGHT DO DAMAGE so double check this advice - I've never done it myself. I think it would be fine.
    If the crank sensor is toast, then the coil shouldn't be putting out spark......
