Help me diagnose my problem ..............
I was moderately accelerating in 4th when the engine started backfiring badly and and shut down. Felt like the time I broke my timing chain in my 1970 GTO. I coasted to a stop and tried cranking it and it would just fire and backfire couple of times. Then it stopped turning over all together. I read the codes and bseides P0300 misfire one was C0336 Crankshaft position performance range .Would a busted timing chain throw this code? I got the car to turn over again but all it does it fire a couple of cylinders and back fire.
Any educated guesses? The chain is a double rollmaster.

OK ... The chain isn't broken. There's no movement or play on the reluctor wheel (Lunati crank) and the sensor was clean so how do I check if it is the wire or the sensor itself? Where and what do I measure? ie: which pins on the plug and what should the voltage be? Would a sensor give out with with no prior signs? The car was running fine and then shut down like a plug was pulled.

Well this is an old thread at this point but to bring you up to date, I took out the motor and took it right down. The reluctor wheel got damaged by a piece of an inner valve spring (crane) that made its way down threw the pushrod hole. It had been floating around the bottom end for a YEAR!! Who knew? It finally got caught between the back of the block and the reluctor wheel taking out several teeth. Nothing else got hurt.
