The computer will not enable spark to the cylinders if it missing the signal from one or both of the position sensors. Inspect the wire harness and connectors for damage or looseness and correct as necessary. If one or both of the sensors has been dropped, hit, or damaged, the sensor may be in need of replacement. Check for a reference voltage at the connector to both sensors. If there is no damage and the sensors tests OK, then there could be a fault in the engine computer. I strongly suggest acquiring a qualified technician to perform an inspection to prevent the replacement of unnecessary parts.
