Make sure that the ignition timing is correct, you have a good spark and fuel pressure, start here.

Thank you for your advice.

The ignition timong is right, spark also good.
However, we noticed that the fuel pressure is abnormal. There are huge quantity of fuel flow when we tried to start the engine.

May I know how to rectify that in order for the fuel pressure to be normal?

Thank you.
