2.2 HDI wont start

[chriscdm]

Hi my 2004 2.2 Hdi Auto stopped on the motorway with no warning lights on the dash the aa plugged in the computer and says it is the cam sensor this part has been changed but the car still wont start, the fuel pumps are working with pressure at the rail the battery was disconected at some point Could this be an imobiliser problem ?

Thanks to any one who can help

If it is an immobiliser fault it should be flagged on the infoscreen.

I would run through the BSI Reset / Battery Disconnect / Reconnect Procedure to eliminate that possibility though, presuming that this wasn't followed the first time.

have you checked the wiring from the cam sensor i had one where the wire entered the plug had snapped the outer insulation was still intact
but the copper core inside had broken it did not "feel right" modern cable seems a lot harder than cable used in cars years ago

Thanks for your replies How common is it for these 2.2 hdi 16valves to jump a tooth on the cam belt

Wont even go with easy start so i suppose would point to no compression ??

What does it sound like when you crank it? I would certainly get the either the belt covers or the rocker cover off and check the belt, however, I think it's odds onthe belt (or chain to the exhaust cam) has jumped or broken. Unfortunately this may well be the end of the engine - the injectors are notoriously diffiult to remove on the 2.2 engine, and they need to come out to get the cam carrier off, to either get the head off, or get to the broken rockers.....

Engine sounds normal when spinning over tries to start a bit, Just had a lexia plugged in and says it is the crank sensor, are these easy to change ? and do they need to be matched to the cam sensor
