Where is 2008 dodge caliber fuel pump reset button?

There is no fuel pump reset button on a 2008 Dodge Caliber (or any other car, for that matter). If you're having fuel pump issues, it's a mechanical problem requiring professional diagnosis and repair, not a simple button press. Possible causes could include a faulty fuel pump, a clogged fuel filter, or a problem with the electrical system supplying power to the pump. You should take your vehicle to a qualified mechanic.
