What are the reasons why a Volkswagen Santana has power but won't start?

[SanEloise]

Volkswagen Santana has power but won't start for the following reasons: Electrical or electronic failure: The occurrence is very sudden, without any warning. Electrical failures include: blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, damaged spark plug. Electronic failure mainly refers to the loss of function of the central computer control board. Fuel system failure: Stalling caused by fuel system failure often has symptoms such as weak engine power and the accelerator pedal feeling like stepping on cotton. Possible locations of fuel system failure include: malfunctioning fuel pump, blocked fuel line, clogged fuel filter, failed carburetor, damaged injector, etc. Sometimes, the fuel tank may be empty without the owner's knowledge. Adding a few liters of gasoline can solve all the problems.
