There's no readily accessible fuel shutoff valve in a 2007 Dodge Caliber like you might find on older vehicles. Modern fuel systems are designed differently for safety and emissions reasons. The fuel is controlled electronically, and shutting off the fuel requires disconnecting the fuel pump's electrical supply. This usually involves accessing the fuel pump relay in the fuse box or, in some cases, more involved procedures requiring mechanical expertise.
Attempting to disable the fuel system without proper knowledge could be dangerous and damage your vehicle.
If you need to stop the flow of fuel for any reason (e.g., a serious fuel leak), you should consult a qualified mechanic or tow your vehicle to a repair shop.
