      Hello.
      I am in need of some help. I have a 2003 Suburban 1500, the wife drove to the grocery store, when she came back out, the car did not want to start. In fact, it wont do anything. The display for the gears comes on as soon as the key is inserted but then goes off as the key is turned to the on position. Nothing works at this point, and there audible clicks coming from the fuse box under hood, as well as from the throttle position sensor on the throttle body. Battery is charged, connection is tight, no corrosion. The BCM had been acting up, so i got a BCM flashed to the vin but it still does the same thing. I checked the fuses under the hood and they are all fine as far as I can tell. I believe there has to be an electrical or issue somewhere but I have no idea where to start at this point. Anyone had a similar issue?
