I have a 2007 Dodge nitro SLT. Guess what? It wont start. We have replaced the battery and the starter. We got it to start one time after the replacements. We did this by taking the negative of the battery then the positive then waiting 10 minutes. and replacing the positive then the negative like another forum had said. It started that one time and we went back out to start it again and it will not start. It cranks over one time and then tries to crank again but no luck. Please please help me here. I am a visiting nurse and I need my nitro to drive for a living.
