The fuel delivery system is comprised of the fuel pump, gas tank, fuel relay and fuel filter. These all need to function properly for the fuel to get to the fuel injectors. If you are having engine starting problems, loss of power, and the engine coming to a stop like running out of fuel, or no fuel pump sounds these are all fuel delivery system problems. For the home mechanic enthusiast, who wants to check the pressure in the fuel pump, the owner’s manual specifies the location of the test port for your Mercedes fuel pump. A pressure gauge can be attached to the port identified. Watch the gauge while the engine is idling and see if it matches what is in the owner’s manual. It can run between 20 to 80 psi of fuel pressure, but check your manuals instructions, and whether it is within range for the vehicle.

When the fuel pump runs too high it is considered too rich in fuel and it may cause some black smoke out the tail pipe and poor gas mileage. When the pressure is too low it is considered too lean and will have poor engine performance. This also will usually indicate a clogged filter or a failing fuel pump. If there are grinding noises when you try to start the vehicle, but no starting, it is not the spark plugs but the fuel delivery system. Another problem is the loss of power and the engine just slowing down for a bit and then it may pick up again. However, with this problem it may not start up again and could leave you stranded. When the engine starts only for a moment, but then shuts down again, there may not be proper and continual fuel going to the fuel injectors.

A fuel pump relay may cause a Mercedes-Benz to stop while driving and not come back on again for a while. The fuel relay function is to simply turn the fuel pump on or off. The whole engine cycle is initiated by the relay coming on for about 2 seconds for a boosted start. If it doesn’t start the relay needs to be checked. Also, if you are cruising down the road and then there is silence the fuel relay can also turn the engine off, so it will need to be considered in your repair, when checking out the fuel system. The electric fuel pump is located in the fuel tank and cooled and lubricated by the fuel itself. However, access can be achieved from either under one of the back seats, in the trunk or from under the auto. Since the fuel needs to be drained if your only access is to drop the tank, it makes this repair hazardous and best left to the certified professionals, who have the specialized equipment and well ventilated workshop to handle the repair safely.

If the Mercedes has a secondary fuel pump, it is located near the engine and boosts the fuel pressure to what is needed by the fuel injectors.
