Please what could be the cause of S92 APU not starting with error code 010 power unit shutting down due to start fault. Everything pointed at in the corrective action has been carried out, problem still exist?

Just to confirm - have you swapped out the sequence unit with either a new one, or borrowed one off another S92A (if you have one)?

Problem with this style of fault is that it can be numerous things - from the ESU, the sensors or the wiring looms. Have you done individual wiring continuity checks as per the later parts of Chap 49?

Highly unlikely to be the ESU from experience

APU speed sensor?
