Electrical problem
2002 Dodge Intrepid 6 cyl Four Wheel Drive Automatic

i recently purchased a car with a remote car starter and the vehicle will start with the remote but won't stay running. The car sat for about a year and the battery was dead and had to be jumped I read in the manual that this can damage the remote if the car starter wasn't turned off which it was not I read this after the fact.
