I couldn't start engine with main pump. It worked only after start engine with auxiliary pump.
Than we discovered that this pump has 9,44 voltages compare to auxiliary pump - 12,44.
We have an oxidized pin no. 11 of the connector which supplies minus on the main fuel pump.
We cleaned it and used anticorrosive spray for electrical contacts to remove the corrosion.
Today I have had flight about 1 hour. But on the back way I cannot start engine with main pump. The same problem appeared that before.
