Volvo D5 185BHP CP3 High Pressure Pump Control Valve Fuel Flow Check - Second Stage

Описание: Hi,

My 2007 Volvo XC90 cranked but did not start. Low pressure pump sends fuel to high pressure pump but then fuel would NOT get to common rail - Bosch CP3 0445010111 HP pump is not pumping fuel through outlet.

In this video I've removed the hex bolt that gives access to pressurising shaft. I turned the key to Position II for like 1 second (and not cranking the engine) and yes again...it is flowing. Then I crank the engine the pressurising shaft moving. Next stage would be checking if fuel would get to the outlet.

Car is now sorted. The issue I had was...I had not done the priming correctly, therefore there were lots of air in the fuel line. I did the key On and OFF cycle for over 20 times (as advised by Volvo) and then car started straight away.

If you remove any fuel system line (like a hose or a banjo bolt or high pressure pipe etc), it sucks air in then stops sending fuel to common rail. When you turn the key to ON (ignition on) and if you have air then you could hear fuel flowing in there inside the fuel filter housing under rear passenger seating location. So you have to prime until you hear nothing but whining noise. This is achieved by above ON and then OFF method.

Thank you
