1. Difficulty starting the engine: A bad fuel pump may cause the engine to crank but not start, or it may start and then stall immediately.
2. Engine stalling or jerking: A bad fuel pump may cause the engine to stall or jerk while driving, especially under acceleration or when going up hills.
3. Low fuel pressure: You can check the fuel pressure using a fuel pressure gauge. If the fuel pressure is too low, it could indicate a bad fuel pump.
4. Noisy fuel pump: A bad fuel pump may make a whining or grinding noise. This noise may be especially noticeable when the fuel tank is low.
5. Check Engine Light: If your Check Engine Light is on, it could indicate a problem with the fuel pump or other fuel system components.
6. Fuel starvation: If the fuel pump is not delivering enough fuel to the engine, it can cause the engine to run lean and experience fuel starvation. This can lead to engine damage if not addressed promptly.
If you suspect that your 1999 C280 Mercedes Benz has a bad fuel pump, it's important to take it to a qualified mechanic for diagnosis and repair.
