Cam sensor failure doesn't prevent all engines from starting - it depends how they are programmed.

I don't know about the Range Rover, but did you try the Range Rover one in your car?

Re the UBP if you unplug the outlet pipe where it connects to the fuel filter and place it in a large jar, then with key to position II you should get a good strong flow of fuel into the jar.

Mike. Do you mean the diesel engine will start WITHOUT a signal from the cam sensor ???

PS. Been trying to contact this bloke when I'm at home in Teignmouth but never get a response from him.---

Yep but not our engines though John. The only job the cam sensor has is to make sure the engine isn't trying to start 180 degrees out.

You can program a diesel ECM to start injecting even if it doesn't receive the cam sensor signal, and if the engine doesn't fire, phase the injection back 180 and then it will.

Shame Bosch decided not to do this on the M47R.

Worth checking the cam sensor plug where the wires go in - I have had a cable break there.

Hi guys went to have a look at the car on Wednesday a few codes came up mainly cambus error and bulb failure,Brian has checked the ecu,I used the vt4 supplied by Phil t4 nothing sprang out to make me think it won’t start,we’ve got both pumps working,immobiliser light going out,loads of fuel,it’s trying to start when you pump the throttle but just won’t fire,never had this problem before it’s always been fuel related so I’m gonna get a few known working spare bits ie cam sensor etc and have another go I’m not easily beaten so hopefully it’ll work with a bit of persuasion lol hi mike the other vehicle is a Land Rover td4 mk1

The can messaging error is a red herring as it relates to traction control which Harry's car doesn't have.

What were the other fault codes Matt?
