What are the reasons for the Volkswagen New Santana stalling immediately after starting?

[HarperMarie]

It is due to fuel supply interruption. Possible causes include: aging fuel pump with unreliable pumping; fuel pump power failure; check valve sticking resulting in insufficient fuel injection; or incorrect ECU feedback. Electrical circuit faults: This may occur due to low-voltage power interruption while driving, causing stalling. In this case, primarily inspect the ignition and starter switches, as well as the fuse box. Electrical component failures: This issue typically involves the ignition coil, capacitor, or electronic ignition module. The vehicle may start initially but stall after a while, then restart only to stall again. Fuel system faults: Possible causes include: damaged fuel pump, fuel line rupture, carburetor inlet blockage, or empty fuel tank. In such cases, the vehicle may restart but with great difficulty.
