HI i'm new to the forum and was wondering if any of you could help, I've always had petrol cars myself so not that clued up on diesels, my Girlfriend has a 02 reg Clio 1.5 dci its had ongoing issues ever since we have owned it about 2 years now but have not really caused a problem just been a bit annoying, it shows 3 warning lights on the dash (when going over 80mph or up a very steep hill) and throws the codes up for Glowplug circuit, Fuel Rail Regulator. i've had it looked at and made better in the past with another injector and was told another is on the lower limit of flow so i'm pretty sure its an injector problem...
However the last few weeks its been getting harder to start when engine is warm, it turns over fine, doesn't stutter but just won't fire, its been getting worse and today i thought i would service it and take the TDC sensor out and check it and clean it, put it all back together cleaned and checked all connections, went to start it and nothing, turns over fine but just won't fire...
I went down my friends mot garage got his fault reader thing put it on live mode and checked all sensors, it shows engine RPM of 200 even with cam sensor unplugged when cranking so the TDC must be working ok?????!!!!!, it shows fuel flow at 20mg/c?????!!!!, and a fuel pressure of 126 bar plus all the other sensors looks fine showing correct engine temp, correct ambient temp, throttle pos all good, etc etc.
The only thing that looked a bit strange is that manifold pressure was at 1 bar when not cranking and still at 1 bar when cranking shouldn't it cause a vacuum and drop....
I cleared some fault codes with the scanner and i'm wondering if for some reason it might have cleared the Injector programming off the ecu????? or something else. or possibly the injector pump has gone, i think it had a new fuel filter 2 year and 20k miles ago as the dealer said that was the first thing he did when we complained about the lights on the dash, the car has done 90k miles
Any help would be much appreciated i'm scratching my head.
Thanks a lot... Cheers. seb
