| | DO YOU HAVE DIESEL RAIL PRESSURE SHOULD BE AROUND 400 BAR AT CRANKING SPEED IF NOT SUSPECT FUEL PRESSURE REGULATOR OR VERY LEAKY INJECTOR DO A LEAKOFF TEST AND LOOK FOR A 0.5 VOLT PLAUSABILITY VOLTAGE ON THE PRESSURE REGULATOR DO YOU HAVE POWER TO THE INJECTORS GET HOLD OF SOME NOID LIGHTS ABOUT A TENNER FROM A GOOD PARTS SUPPLIER TEST ALL OF THE INJECTORHARNESS PLUGS FOR POWER IF NO POWER THE USUAL SUSPECT IS THE CAM SENSOR THIS FIRES THE INJECTORS IN A ROUNDABOUT WAY, AGAIN A COMMON FAULT ON THE PUGS HOPE THIS HELPS CHEER DAVE P

| | Is the in tank pump working, check for power to the fuse No34 or 35, can't remember which, but it one or the other. It's in the under bonnet fuse box. If no power, no low fuel pressure and hence no high pressure at the rail. The double relay is down behind the ECM, which in turn is behind the battery.
I could give up Stella, but I'm no quitter.  |

| | Hi, Sounds like you have an injector fault which is quite common on the Bosch system. The cranking diesel pressure needs to be above 200 bar for the ECU to initialise the injectors. Due to the low speed at the high pressure pump the pressure is not attained due to high leak back at one or more of the injectors. To be sure of this this the best way to be fairly certain is try spraying some easy start into the induction pipes and if the vehicle starts then you are pretty certain that your fault is low fuel pressure when cranking. You then have to get the leak back checked!! At least you have a start Richard P |

| Paul,
You need to see live data, why replace a camshaft sensor? What is your thinking behind that?
You need a good diagnostic engineer with a good diagnostic tool.
Try good garages link above.
