I've had this happen just a handful of times now. I try to start the car and it's completely dead. Like there's no battery. I had this happen yesterday right after I got done driving. I parked and shut the car off to take a phone call. I got out of the car, left the door open, walked for about a minute or two, then got back in the car. Closed the door, tried to start it and nothing. What I've found is if I go and open the passenger door, then close it, I can then start the car.
Is there a ground point I should be looking at on that side of the car?
