The Monte Carlo has been in and out the Chevrolet product lineup since 1970, finally coming to an end in 2007. Throughout its entire production run the Monte Carlo remained a two-door coupe. Like most modern cars, the Monte Carlo has many mechanical and electrical systems. To troubleshoot the Monte Carlo, eliminate potential causes of the problem you are experiencing with the car.
Look under the 2002 Monte Carlo on a regular basis after the car has cooled down. These regular inspections will reveal any small leaks from the engine, transmission, brake lines or power steering systems.2
Insert the key into Monte Carlo's ignition and turn it to the accessory position. Check the car's electrical systems, including the windshield wipers, fan motor, radio and other systems. If any of them are not working, turn the key back and remove the key from the ignition. Inspect the fuse box located under the dashboard on the driver's side. Remove the fuse and inspect the plastic end, if the metal strip inside the plastic end is broken, then the fuse will need to be replaced.3
Listen to the car when trying to start it. If the car is turning over but not starting, the spark plugs may not be providing a good enough spark to get the Monte Carlo started. Open the engine compartment, disconnect the spark plug cables and remove the spark plugs using a spark plug wrench. Inspect the bottom of the spark plug. Clean the carbon off the spark plug using a wire brush. If the carbon buildup is excessive, then replace the old spark plugs with new ones.
