I have changed the engine (brand new Farymann engine) and some of the wiring on my genset paguro 4000.
As You can see from the video the engine starts up and then dies out shortly. Video here:

It does it every time I try to start it.
I have checked following:
- Selenoid valve for turning off the engine- it works
- Sensors for oil and water temp. there is connection to the control display and I tried to discontenting them when starting the engine but it makes no difference
- I’ve checked( as good as possible) control display and it seems that it works fine.
- I’ve checked that the fuel is coming to the small engine filter
- I’ve tried to pump the fuel through the system with decompression valve on the engine- no difference
- I’ve tried to disconnect the alternator , - no difference

I’m down to two theories:
1. For me it sounds as something is turning off the engine. The engine starts picking up revolutions and suddenly it is just cut off.
2. There is air sucked in on the vacuum side.

Can you please come with some good advice how I can identify the cause of the failure.
