Friend of mine has a 2008 Ram HEMI that ran when parked. Now, it won't start. Turn the key and there's no sound from the fuel pump. There does not seem to be a listing for the fuel pump fuse and I don't see any relays (I believe it's a TIPM which would have the relays on the back). At what mileage are these fuel pumps dying? Anything obvious I can check?
