Comment I received regarding the 2009 fuel filter change procedure. http://www.myturbodiesel.com/1000q_how_to/a5/09Ffilter.htm Can anyone verify?
I have yet to find a 2009 or 2010 (CBEA or CJAA engine) that the fuel pump cycles on for a second or two when the key is cycled.
It seems everyone assumes that they do, similar to the earlier PD engines. I also made this assumption, and when I could not get fuel to squirt out while cycling the key, I initially assumed I had a failed fuel pump. Not so. Both of the electric fuel pumps run when cycled with VCDS.
But the fuel pumps do NOT cycle on when the key is first turned on, on any that I have tried, or for other folks who have done a definitive test.
A definitive test is to put the fuel filter inlet hose into a jar and cycle the key.
