1. Fuel Tank and Line Problems:
* Empty Tank: The most obvious! Check the fuel gauge.
* Clogged Fuel Filter: A dirty fuel filter can restrict fuel flow. This is a common issue.
* Fuel Line Blockage: Corrosion or debris can clog fuel lines, especially older ones.
* Fuel Pump Failure: The fuel pump is responsible for moving fuel from the tank to the engine. If it's not working, you won't get fuel.
2. Carburetor Issues:
* Clogged Fuel Inlet: The carburetor has a fuel inlet that can become clogged with debris.
* Float Problems: The float in the carburetor regulates fuel levels. If it's stuck or malfunctioning, it can prevent fuel from entering the engine.
* Diaphragm Problems: The carburetor's diaphragm can tear or become brittle, hindering fuel flow.
3. Ignition System:
* Spark Plugs: If your spark plugs are fouled, they can prevent the engine from running, leading to fuel not being used.
* Ignition Coil Issues: A malfunctioning coil won't generate the spark needed to ignite the fuel-air mixture.
Troubleshooting Steps:
1. Check the Fuel Gauge: Make sure the tank isn't empty.
2. Listen for Fuel Pump Noise: With the key in the "ON" position, but not running, you should hear a whirring noise from the fuel pump (usually near the fuel tank). If you don't, the pump may be faulty.
3. Check for Fuel at the Carburetor: With the key in the "ON" position, carefully disconnect the fuel line at the carburetor. Turn the key to "START" and see if fuel comes out. If it doesn't, the problem is upstream.
4. Inspect Fuel Lines: Check for any visible kinks, cracks, or signs of rust.
5. Replace Fuel Filter: Even if it looks fine, a new filter is a good idea.
6. Inspect Carburetor: A visual inspection might reveal debris or damage. If you're not comfortable with this, it's best to consult a mechanic.
Important Safety Considerations:
* Work on a Cold Engine: Always allow the engine to cool completely before working on it.
* Avoid Fuel Spills: Fuel is highly flammable. Keep rags and other materials away from it.
* Use Eye and Skin Protection: Wear eye protection and gloves when working with fuel or under the hood.
Need Help?
* Consult a Mechanic: If you're not comfortable working on the fuel system, it's best to have a mechanic diagnose and repair the problem.
* Research Your Car: The Haynes or Chilton repair manual for your specific year and model Chrysler Fifth Avenue can provide detailed instructions and diagrams for your car.
