What causes weak engine ignition?

[StHolden]

Weak engine ignition can be caused by the following reasons: Electrical or electronic faults: The symptoms often appear suddenly without any warning. Electrical faults include: blown fuses, open circuit in high-voltage coils, open circuit in low-voltage circuits, detached central ignition wire, distributor rotor leakage, or damaged spark plugs. Electronic faults mainly refer to malfunctions in the central computer control panel. Fuel system faults: Stalling caused by fuel system issues often comes with symptoms like weak engine power and a spongy accelerator pedal. Possible fuel system fault locations include: fuel pump failure, blocked fuel lines, clogged fuel filter, carburetor failure, or damaged injectors. Sometimes, the fuel tank might be empty without the owner realizing it. Adding a few liters of gasoline can solve all these problems.
