How to Troubleshoot the Fuel System in a Dodge Caravan

Check the fuel level and review the starting procedures. If the engine won't turn over from a cold start, make sure the engine isn't flooded, the fuel filter clogged or the choke defective.

Suspect a defective choke when the engine won't start when hot. Make sure there's sufficient fuel. Check the choke plate.

Look for dirt or moisture in the fuel when the engine runs rough. Make sure the fuel pump is working properly. Check the air filter for clogs.

Blame poor gas mileage on a dirty carburetor or clogged air filter. Clean the carburetor and replace the air filter first. Suspect a defective choke when the problem continues.

Adjust the choke of the carburetor when the engine won't start and the smell of gasoline is present. Lift the hood and check the carburetor. Wait 15 minutes before another attempt to start the engine. Turn on the ignition without pumping the gas pedal.
