This one was pump, unfortunately.

Also have a focus here with the same codes and driveability issues.

I think that I can safely bypass signal tests etc and go straight to a sealed rail kit to prove pump integrity first from now on with these codes.

Are these particularly common does anyone know? The fact I have two may just be coincidence?!

Thanks to all that gave input.

Any recommendations on makes/suppliers of a sealed rail kit and pump dummy kit?

Liam.
