With a multi meter it should read about 800 ohms across the sensors terminals with it unplugged. When they test bad they usually read as a open let me know what you find.

Did you check your crank shaft position sensor yet?That's going to be way more likely the module or both coils going bad at the same time.

Both coils were checked I tested them by reeplacing them one at and checking spark across the top with wires off, no spark coils good reinstalled original coils. Removed modual and installed a good used one. Car startes right up.

Had a feeling it was the module I have never seen both coils fail at the same time glad to hear you got it fixed.
