What's causing low fuel pressure in my Honda Accord?

On the diagnostics it says pressure too low on the fuel rail system on my 2009 2.2 Honda Accord diesel? Is there an adjustment that can be made on the diesel pressure pump or what is the solution please?

Hi Gary,

There is no adjustment to be made. We spoke to Honda Ireland about this and it's suspected that fuel contamination and/or a blocked fuel filter is to blame.

First thing to do is change the fuel filter, clear the code and try it again. Honda says it would normally look at what is in the old fuel filter before running the car again, as it may reveal a need to drain and clean the fuel tank.

Let us know how you get on
