Dear Ahdash,

Normally after failed firing attempts, fuel get accumulated in combustion path, which if not drained properly through drains, will cause exhaust temperature to go high during subsequent start-ups.

the problem, there is no indication on the wheel temp. however firing was ok and speed reaches 5100rpm.
