I deal with NAPA on a daily basis. Have them order you a new one and when it comes in, swap it out. Your store will send it back and whether good or bad, you won't hear anything about it.

Since the CPS sometimes has heat or intermittent issues, checking it off the car is not very accurate unless it completely fails. On other cars, using an OBD reader, (haven't tried it on the Crossfire) you can check the engine rpm when cranking. If it shows no rpms while cranking, then you know it is bad.

Also there is cam sensor you need to check for the same symptoms.
