When the vehicle door opens or the ignition switches on, the LPi pump must run for a predetermined time (typically 2 to 5 seconds) to flush out any vapor bubbles. Listen for the distinct hum of the tank pump.
If you need help with a specific repair or diagnostic issue, let me know:

Technical Guide: Understanding and Servicing the Vialle LPi System
The factory injector ground wires are cut and routed through the LPE. This allows the LPE to read the pulse-width modulation (PWM) signal and stop the gasoline flow when switching to LPG.
The system represents a significant shift in LPG technology, moving away from traditional vaporizers to a system that injects LPG in its liquid form directly into the engine's intake valves. This "liquid phase" approach allows for more precise fuel metering, mirroring the behavior of modern petrol injection systems to maintain engine performance without power loss.
