I have an 04 crossfire and it wont start. At first for 2 weeks the cars battery would go dead if u let it sit for more than a day. Then one day I was driving the car the battery completely died and the car wouldn't stay on and it would crank but would not turn completely over. I bought a new battery and alternator and its holding a charge now but the car will still crank but will not turn over completely im not sure what the problem is im thinking the crankshaft position sensor but if that was bad the car would at least turn over but not stay on any suggestions?
