Are you sure it isn't the injectors you can hear?

james m · February 18, 2011

yes, coz when ticking noise starts i can see fuel pump moving at the same time

Fuel pump is under the back seat....in the fuel tank.

Are you sure you're looking at the pump? And not, say, the fuel pressure regulator at the end of the injection rail?

Sorry. Before anyone scolds me, the fuel pressure regulator is on the fuel pump as well.

The small device on the end of the injection rail is the Fuel Pressure Pulsation Damper.

And, james m, the piston on the Fuel Pressure Pulsation Damper will move in and out and may click because the fuel pressure in the lines is rapidly changing due to actuation of the injectors.
