C5 2.2Hdi Won't Start

[Andrewwood]

Hi everyone

 

I have a 2005 C5 2.2HDI Auto exclusive and this morning went to start it and it wouldn't.

 

First thing the computer said coolant level too low, been having to top it up for a few months now and always thought head gasket was on way out but there is no pressuring in expansion tank, or bubbles or mayonnaise anywhere.

 

Anyway turned key and it fired for about 5 seconds and misfired and cut out. Tried again and starter motor was very reluctant to turn over to the point where the starter was turning but not engaging.

 

Tried it again and it went to fire but cut out almost immediately, then tried it later this afternoon it fired for a few seconds then misfired and cut out.

 

Question is does it seem like head gasket even though it hasn't been pressuring or no water in oil, I.e. Can water get between cylinders and not be seen, by the way there has been no white smoke.

 

Thanks in anticipation

 

Andy

youl be chasing your tale forever by trying to gues the fault. you need to have it plugged in and go to live data. thats the only way you can see why its not starting

Has the engine management light come on and not gone off when it has run for a bit ? You could try priming the fuel filter if there is a hand primer or turn the key in the ignition and wait a few seconds before trying to start it - just in case it is a fueling problem, or try some easy start.

Update: it started this morning, however, engine management light on, and copious amounts of white / grey smoke with a diesel smell. Also comes up with de pollution system faulty, could it be injector fault as I've only been averaging 32 to 34 mpg, still got concerns though about why it's using so much water,

Thanks

Going to connect my Lexia to it now and see what's on there if I can understand it
