My Mercedes 300E Won#039;t Start amp; Is Not Getting Gas


1. Check the fuel gauge to make sure there is gas in the fuel tank. Add at least two gallons of gas to the fuel tank -- if you have an electric fuel gauge to cover the possibility that the fuel tank is empty.
2. Crawl underneath the vehicle and locate the fuel tank near the rear of the vehicle on the passenger's side. Inspect the fuel tank for holes or rusted areas. Look for fuel on the ground underneath the fuel tank which could indicate a fuel leak.
3. Locate the fuel line that connects the fuel tank to the engine. You should be able to identify it as a black hose about three inches in diameter. Trace the fuel line from the fuel tank to the engine area and look for areas of corrosion. Feel the fuel line from dampness that could indicate a possible fuel leak.
4. Locate the fuel filter along the fuel line. Depending on the year of your vehicle, the fuel filter may either be mounted underneath the vehicle or underneath the hood along the firewall. Check your owner's manual for the exact location of the fuel filter. Inspect the fuel filter for excessive dirt, which can clog the fuel line preventing fuel from reaching the engine.
5. Locate the fuel pump near the area where your fuel line just meets the engine. Inspect the fuel pump for corroded areas, excessive dirt, or frayed wires. Replace the fuel pump, if necessary. A faulty fuel pump will fail to send fuel to the engine.
