I have a 2004 Chrysler Pacifica AWD. I'm getting code readings p0302- cylinder 2 misfire, p0202- injector circuit open cylinder 2, p2305- ignition coil B secondary circuit, p2317- ignition coil F secondary circuit, p0300- random multiple cylinder misfire detected, p0700- trans control sys malfunction, and p0562- system low voltage. I've replaced the coil pack in cylinder 2 and the injector and my car still won't start. What else do I need to do. Please help me.
