 - make sure that the LP fuel valve is open (Ref. AMM TASK 28-24-00-710-002).
 (1) If the valve is not open:
 - do a check of the aircraft wiring between the circuit breakers (2QG), (4QG) and the ENG 2 LP fuel valve actuator (10QG) pins AA/A, BB/A (Ref. ASM 76-12/01) and (Ref. ASM 28-24/01).
 (a) If there is no continuity:

 - repair the above wiring or/and replace the RELAY-ENG/MASTER 2 (12QG).

 (b) If there is continuity:

 - replace the ACTUATOR-LP FUEL VALVE, ENG 2 (10QG) (Ref. AMM TASK 28-24-51-000-001) and (Ref. AMM TASK 28-24-51-400-001).

 (c) If the fault continues:

 - replace the VALVE-LP FUEL, ENG 2 (13QM) (Ref. AMM TASK 28-24-41-000-001) and (Ref. AMM TASK 28-24-41-400-001).
 C. Test
 (1) Start the engine 2 by the engine automatic start procedure (Ref. AMM TASK 71-00-00-710-003).

 (2) Make sure that there is no ECAM and CFDS fault message shown.
