I have a 2005 Durango 4.7 Magnum. A couple of weeks ago the SUV started on its own and shut off. A couple of hours later I went to leave and using the key it started and shut off 4 times and then nothing. It has a viper remote start on the SUV and nothing works. I changed the starter and checked all the fuses and relays and everything is good and everything has power and the starter still won't do anything. Does anyone have any idea's?
