• Problem: Engine stalls during cold start. Solution: Check coolant temperature sensor resistance (manual specifies 2.5kΩ at 20°C).
• Problem: LPG pump runs continuously. Solution: Verify the crash sensor ground (manual provides bypass test procedure).
• Problem: Rough idle on LPG. Solution: Perform injector balance test (manual provides voltage drop thresholds).

: The cooling effect of liquid evaporation in the manifold improves cylinder filling and prevents "backfire" damage common in older vapor-phase systems. Motor-Talk Maintenance and Troubleshooting LPI Vialle Technical Manual: A Comprehensive Guide Vialle

Common Troubleshooting: The manual identifies typical issues such as tank pump failure, gas solenoid faults, and misfires often caused by water damage to electrical connectors. Problem: Engine stalls during cold start

1. System Context

The Vialle LPI system injects liquid LPG directly into the intake port (not vapor). It uses a high-pressure pump (inside the LPG tank), a liquid LPG filter, a vaporizer/heater, and liquid-specific injectors. The “TOP” in this manual context refers to:

Poor Running: Often linked to gas solenoid failures or clogged injectors. Technical Benefits & Drawbacks Benefit/Detail Emissions Naturally cleaner; lower CO2, NOx, and HC levels. Performance

LPE Control Unit: The "brain" of the system (common versions include LPE-7) which manages the switching between fuels and regulates injection duration.
