93 regal no spark 3.8 motor,had ingnition module checked at autozone its good replaced crank senser cam senser to code 42 sets all the time please help.

if it's not the igntion module, then you may want to check your wiring. make sure that there aren't any loose connectors on the upper part of the engine. You may also want to check your grounds.

If you still have a problem after all of this, then you might need a new ECM.
