look at the engine speed on tech2 if it's going up to about 180 rpm then crank is ok,
best way to check cam and crank are in sync is to watch the check engine light when you start cranking, it should be solid on with just ignition then go out and stay out when you start to crank the engine over. if it flashes once at you and the rpm reading on tech 2 only gets to about 100rpm then the cam and crank are not in sync |

Hi Eathan, these are the numbers: rail oil pressure 5.3
Engine speed: 105 rpm
: rail pressure control valve 39% |

| i think it's the engine speed thats the issue, would you say (as i can't hear it) that it's spinning over at normal speed? if so and it's only registering 105rpm then i would be checking the timing to make sure everything is on tdc at the same time. it hasn't had the flywheel changed has it? |

if I could only find out how to put up pictures and video I could put a video up with all that, no I have not done any fly wheel change and the car was driving when it quit I have a new battery and a battery charger on at the same time on boost and it sounds normal to me, changed the crank and cam sensors with two used ones and am now charging the battery to try a start later |

| don't get the cam and crank sensors mixed up as they look the same but they don't work if you swap them round for some reason |

So I changed the crank sensor and the car tried to star about four times but did not catch, now just cranking again, WTF? |
