Fuel delivery is controlled electronically and through various safety systems. If you're experiencing a fuel-related problem, the issue is likely elsewhere:
* Fuel pump failure: This requires professional diagnosis and repair.
* Fuel filter blockage: This can be replaced by a mechanic or, depending on your skill level and the Caravan's year, possibly yourself (check your owner's manual).
* Electrical issue: A problem with the fuel system's electrical components could prevent fuel delivery. This needs professional diagnosis.
* Other fuel system malfunctions: Numerous other components in the fuel system can malfunction, requiring professional diagnosis and repair.
If you're experiencing a problem where you believe the fuel supply is cut off, do not attempt to bypass any safety systems. Instead, contact a qualified mechanic or roadside assistance. Attempting to tamper with the fuel system without proper knowledge is dangerous and could cause serious injury or damage.
