If the engine is throwing a cam or crank sensor code or it cranks over but does not start due to no spark, the cam sensor inside the distributor and the crank sensor could be faulty. Both need to be checked and replaced as needed.

If you have ALREADY replaced the complete distributor assembly, then the crank sensor could be faulty causing this condition. Sometimes the computer can get confused and flag a cam sensor code if the crank sensor signal is faulty or erratic.

Another possible cause would be a faulty new cam sensor inside the distributor assembly. This does happen from time to time. IF this is the case, it should be replaced under warranty.

Also, be sure to check the wiring running between the cam and crank sensors and PCM
