Wire harnesses and fuse holders—typically situated in the engine compartment—must be moisture-sealed to prevent voltage drops or system dropouts. Common Faults and Solutions Probable Cause Manual Recommendation Rough running / Misfires Clogged liquid gas injectors or bad LPG fuel quality. Clean or replace injectors; check fuel rail pressure. No pump noise at start Blown fuse or faulty PTC pump motor.

: Issues often stem from gas solenoids, tank pump degradation, or water damage to electrical connections. Maintenance Requirements
: This section covers the critical step of removing the intake manifold for injector installation. Notably, the disassembled manifold must be sent to Vialle, which returns it with the LPi injectors already fitted—a reflection of the precision required for liquid injection systems.
