Could be one of a few probs.
looking at your posts, you have had a few issues with this. Get a decent engineer to sort it.

As Chalked says. Need to be in front of a firebird. Treat yourself to somebody familiar to the beast.

Could be any number of things, I would check the check valves first. Failing that better get someone out thete are a lot of things that need checking
