The car was running fine but had a radiator leak.. pulled the radiator no problems put the new one in still had no problems. filled the radiator and went to start the car to burp the system and it was only fireing on 5 cyl. pulled the plug wire off num. 2 cyl. and found i was not getting any spark. i changed coil packs and still nothing on number 2 cyl. changed plug wires and plugs still no change so i changed packs again still nothing..Help

The coil pack unit's circuit #3 drives plugs #3 and #6 directly from the PCM. If the cam sensor was defective, it should not fire any plugs. Suspect bad wiring from the PCM to the coil pack, the PCM unit itself, or a segment of the camshaft position sensor surface has lost magnetism causing missing signal to the PCM. An oscilloscope is the best test instrument for chasing down a missing pulse problem. The missing timing signal also explains why the PCM would report a 'bad camshaft sensor'. Hope this helps!
Testimonial: "I appreciate the in depth explanation of what could cause those specific plugs not to fire. I was told to maybe try changing the crankshaft pos. sensor. I figure it can't hurt. Thanks a lot."
