Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

    Could be the fuel pump. I'm not too familiar with renaults but in some cars when you turn the key to the warning lights stage there is a slight hum noise for a second coming from the pump priming. This could be the problem.

    Is it a diesal or unleaded?

    if its petrol it could be the crank position sensor for hard starting.
    as for power can be many things like plugs,coils,timing throttle body.
    need some more info...

    I'd still say take a look at the pump then followed by other posters suggesting plugs, points, crank sensor etc.
    Only other thing is maybe the o2 sensor but the engine should still fire up
