When diagnosing a gas smell in your 1994 Cadillac DeVille, it's essential to adopt a systematic approach that prioritizes simpler checks before delving into more complex issues. Start with a thorough visual inspection of the vehicle, focusing on the areas around the fuel tank and under the car for any signs of fuel leaks. Pay close attention to the fuel lines, as any damage or corrosion can lead to leaks that produce a gas odor. Next, inspect the fuel injectors for any visible signs of leakage, as faulty injectors can allow fuel to escape into the engine compartment. Additionally, examine the evaporative emissions system, which includes components like the charcoal canister and purge valve, as malfunctions here can also contribute to the smell. Don’t overlook the gas cap; ensure it is tightly sealed, as a loose or damaged cap can release fuel vapors. Finally, check the exhaust system for any leaks or damage that might be allowing gas odors to enter the cabin.
