    MK3 Starting Problems

    MY parents 1.6 8v mk3 astra is refusing to turn over. In the past 4 weeks its had 3 new starter motors fitted, the first 2 working fine for a few days before spinning but not engaging with the engine. A third was fitted on thirsday and at first worked fine but now when they key is turned the dash lights up but the starter doesn't even click.

    Any ideas what the matter is?

    I don't like to state the obvious, but it sounds like a bad earth to the engine or a flat battery.

    Thanks for the replies gents.

    Can confirm its not a flat battery as lights, indicators etc are working, plus we hav plug in battery tester that seems to show it as being ok.

    Don't mean to sound thick, but when it comes to this sort of stuff i am! - how would i solve or check for a bad earth? would that have something to do with the starter having been fitted recently?

    I've found out today that the head gasket appears to have gone so is it possible for the ECU to be preventing it from starting?

    To confirm it's not the battery, switch the lights on then try to start it. If the lights go out, it's probably the battery or the main earth.

    One of the battery cables goes to the bodyshell somewhere, that's the main earth. Sometimes there's another to the engine but more often there's a hefty cable connecting the engine block to the bodyshell. Find it, make sure it's tight and if it is check for rust at the body end. As long as it's tight, the engine end is rarely a problem rustwise.

    Next time your car doesn;t start run a jump lead from the battery negative to a good solid bit of metal on the engine. This bypasses all possible bad engine earths
