Stevey Y Posted May 4, 2022 Share Posted May 4, 2022 Hi check the cam belt has not slipped that would cause these symptoms, I have seen very similar before where the belt has jumped a tooth, only other possible culprit is the fuel rail pressure regulator is stuck.

Steve. Hi another thought is run a false fuel supply to the HPFP and try that if it starts that will nail it down to a fuse/relay. Quote Link to comment Share on other sites More sharing options...
