MY CAR WONT START, BUT THE ENGINE TURNS OVER FINE. I HAVE ALREADY REPLACED MY IGNITION CONTROL MODULE.

1990 Mazda MX5 • 4,600 miles

I have a 1990 mazda miata, recently I have had a new motor put in the vehicle. Motor and motor only. The can was driving perfect and suddenly shut off while coasting in fith with the clutch out it would not start, apon stoping the car will crank and the engine turns over fine. I can unplug any plug wire and ground it to the block with a spare spark plug in it, there is no spark. In a haynes manual my coil pack should ohms out between 10.5 - 15.5 both coils 1/4 and 2/3 ohms out at 12.33. I have replaced my ignition control module wich is on my passenger side fender well, my coil pack is on the back driver side of my engine with my crank angle sensor on my back passenger side of the engine. I am at a loss, the only thing I havent replaced is my crank angle sensor, and my ECU

Pay close attention to the crank pulley and crank sensor, make sure the sensor didnt come loose and not picking up signal from pulley, also make sure the wire from ckp sensor is routed correct and is not rubbing on anything that would have damage the wire, in the past I have seen the key way on crank to get worn out and causing it not to start, but u have a new engine so dont think that is the problem.
