Dead cam sensor.
PS. Be very, very careful with the high pressure injector feed. Oil can penetrate your skin and kill you.---- |

So what are the fault codes (if any) and what are the live data figures for the LP and HP side, regulator current etc. Brian |

Engine doesn't need to be running David, LP side must be > than 125Kpa, and the HP side >14000Kpa during cranking.
If the LP is <125KPa, the ECM inhibits injector operation to prevent HP pump damage Brian |

For injector timing the ECM uses the crankshaft sensor. . Last edited by Mike Noc; 7th September 2019 at 07:33.. |
