    I have a Volvo G 930 grader that keeps throwing a high fuel rail pressure code on the dash and cutting off, when it happens I have to pump the primer bulb up to get it running again but after a hour or so it happens again. I have no idea how to check this so any advice would be helpful before I have to send it to the dealer.

    I suspect you will end up talking to your Volvo dealer to help diagnose that. It’ll require VCADs to connect to that thing. Their a bit of an oddball. ESPECIALLY with the 2 little plunger pumps run off the camshaft. They also operate at fairly high pressure (I don’t specifically know on those, but lots of those systems operate at 26-28000psi) so it’s easy to lose a body part.

    Its a common D7 engine and there a pressure switch on the end of the fuel manifold. Replace that you should be good to go
