Hi Mark,

Use a handheld pump or syringe. Your understanding of attachment to the turbine is correct.

A pump start voltage of 2V is excessive. The Jetcat Instruction Manual states normal values are between 0.10-0.325V.

I’m of the opinion that you have a fuel restriction to the burner valve as it runs normally following a successful start. Have you carried out a burner valve test downstream of the solenoid valve? If so, what was the lowest pump start voltage obtained when the fuel commenced to dribble to atmosphere?

If you have another Jetcat then consider replacing the fuel pump and if that doesn’t work change the burner solenoid valve as well.

Regards,
George
