I'm just wondering what the best way to test a high pressure fuel pump as I'm thinking it could be causing issues. The only way I can think of is by removing an injector and turning it over so see if fuel is getting there.
Also what are the most common failures. Am I right in saying the pump relies on the fuel pressure sensor on the rail to work? So could that be the fault? Any more info from someone with more experience would be appreciated.
