What are the reasons why a Mercedes-Benz C260 won't start despite having electricity?

1. Possible electrical or electronic faults: The phenomenon occurs very suddenly without any warning. Electrical circuit faults include: blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plugs. Electronic faults mainly refer to the central computer control board losing functionality. 2. Fuel system faults: Stalling caused by fuel system faults often presents with symptoms like weak engine power and a throttle pedal feeling like stepping on cotton. Possible locations of fuel system faults include: fuel pump failure, blocked fuel lines, clogged fuel filter, carburetor malfunction, or damaged injectors. Sometimes, the fuel tank may be empty without the owner realizing it. Adding a few liters of gasoline can solve all the problems. 3. Mechanical faults: Common mechanical faults include: timing belt (chain) breakage, cylinder leakage with no compression, etc.
