I have an 05 SRT-6
Car does not start. was driving fine up until this morning when I went to start it, everything came on fine but car would not turnover. i came home from lunch got in car started fine drove around for 20 minutes then parked it. went back to work came home tried to start it again and still would not turn over.

I know this has been discussed several times on this forum so I checked the Battery which, yes it still has the factory battery, car only has 21000 miles. Took battery to autozone for testing they initially said it was low and then charged it and tested again and said it was good. installed the battery back in the car, nothing.

I pulled the RCM too and checked the solder joints, they appear to be ok. I was thinking of purchasing a battery anyway just to eliminate that as a cause, but at $154.00 I'd like to be sure about it.

Any other suggestions? I really want to drive my car again.
I was having the time of my life until today somebody please help.
