ok ok, I know its not exactly a performance vauxhall as such - but I need a hand with my new diesel vectra.
Basically when you start the engine, wait for the glow plug light to go out - then start it. I have no problems with it running, but the glow plug light intermittently comes back on when the engine is cold.
It is only when the engine is cold though, if I leave it an hour or so after I have been somewhere and get back in it - I have no problems.
I have replaced the relay/control unit for the glow plugs and that has made no difference.
I am a bit stomped as to what the problem may be.
Basically if (when its running) I leave the light and drive normally it can stay on for 20-30seconds, however if I dip the clutch and blip the throttle to about 3000 rpms then it goes away straight away.
Any pointers on things to check would be greatly appreciated.
