* Fuel Pump Failure: This is the most probable culprit. A failing fuel pump can't deliver enough fuel to keep the carburetor bowl full. Listen carefully near the fuel tank; you should hear a whirring sound when the key is turned to the "on" position (but not starting). If you hear nothing, or a weak whirring, the pump is likely suspect.
* Clogged Fuel Filter: A clogged fuel filter restricts fuel flow. This is a relatively cheap and easy part to replace, so it's worth checking first. Locate the filter (usually near the fuel pump or carburetor) and examine it. If it's dirty or you can't see fuel flowing through it when you prime the system, replace it.
* Fuel Line Restriction: A kinked, collapsed, or partially clogged fuel line can prevent fuel from reaching the carburetor. Inspect all fuel lines visually for damage.
* Fuel Tank Issues: The fuel tank could be clogged, have a bad pickup tube, or simply be empty (though you mention the bowl is dry, which suggests a supply issue rather than just running out). Check the fuel level.
* Carburetor Issues (less likely, given the dry bowl): While carburetor problems *can* cause fuel starvation, a completely dry bowl usually suggests a fuel delivery problem *before* the carburetor. However, possible carburetor issues include:
* Clogged jets or passages: Less likely to result in a completely empty bowl, but possible.
* Float level problem: The float in the carburetor might be stuck or adjusted incorrectly, preventing the bowl from filling properly. This is more likely to result in a partially empty bowl, but if the problem has persisted, it might have drained completely.
Troubleshooting Steps:
1. Check the fuel level: Make absolutely sure your gas tank isn't empty.
2. Listen for the fuel pump: Turn the key to "on" (not start) and listen for the pump.
3. Inspect the fuel filter: Check for clogs or debris. Replace it if necessary.
4. Visually inspect fuel lines: Look for kinks, cracks, or obstructions.
5. Check fuel pressure (if possible): A fuel pressure gauge will definitively tell you if your pump is delivering sufficient pressure. This requires a fuel pressure gauge and the knowledge of where to connect it.
If you're not comfortable working on your fuel system, take your vehicle to a mechanic. Improperly handling fuel can be dangerous. Remember to always disconnect the negative battery terminal before working on the fuel system.
