Anyway, I turned it off and tried starting her again just to make sure, and it wouldn't start, but the rev counter needle went up to about 6,000 revs and stayed there, when I turned the key off, the needle came back down but it wasn't smooth, it was jumpy.
Tried starting her one last time whilst pumping the accelerator pedal and she burst into life, then died again. So I did the same again, and when she started, blipped the throttle a few times and then she settled into her normal idle.
Obviously I had been driving her around during the day, turning off when parked up etc. Sometimes she would start up again absolutely fine as normal. Other times she would do the exact same again, just not turn over for a while like the battery is completely dead. Eventually, she would start again with a few pumps of the accelerator.
What I have also noticed, is that when she did start again, the CD player had reset itself (i.e. no radio stations saved and all setting for bass/treble etc were lost)... strange.
Anybody any ideas what this might be? Somebody has suggested it might be starter motor?
Bit worried about driving her at the moment and being stranded because she won't start!
Cheers guys
