    Yea we were putting it in 3rd when we were towing.

    The engine is turning great today though. I couldn't believe it :thumbup:

    I just dont get why it wont turn over once everything is linked up ?

    Its got me baffled as ive never had this happen before ?

    I wonder if i do need another engine, or need a new starter. [:s]

    just a quickie does it turn by hand ie spanner on crank?
    does it turn with the starter fitted? by hand
    does it turn with gearbox fitted? by hand in neutral
    does it turn via starter motor? with all the above fitted does it click?
    imobliser on the ecu ? who removed it is it pukka!

    even a tired starter can spin on the bench test, swap it for a known good one if theres one lying around before you buy one.

    I wonder if you "hydraulic" locked the engine with fluid of some sort?
    (having said that, you did have the plugs out and same deal).

    WD40 the bores with the plugs out and then put the car in 2nd and rock the car fore and aft...just to get the pistons eased - it's the method the pro's use to recommission engines that have stood a while.

    My tip is borrow a good and tested - known working starter motor. :)

    Yep

    Yep

    Yep

    Yep, it just clicks. It just doesn't want to turn the engine over ?

    Not sure why though as it turns freely by hand [:s]

    Andy out did the Imob on the ECU. Would of thought it was ok :thumbup:

    Think i'll do this Collie and see what happens. :thumbup:

    Ive aready put WD40 down the down the bores, this is what made the engine un-stick and was able to turn it freely by hand afterwards :thumbup:

    It might be a poor earth between starter and battery, have you painted the gearbox? Because tha starter earths to the gearbox housing which needs to be clean bare metal. Also the earth strap from gearbox mount arm to battery must again be a good electrical contact.

    Yea all the earth are good smudge. Ive even cleaned the contacts on all the earths before.

    Its good that the engine is now turning freely by hand, but it refuses to turn via the starter motor ?

    Fuel is getting through fine. Battery is fine. Its just got me baffled [:s]

    If the engine now turns freely by hand then the only things left could be:

    Duff battery
    duff starter
    poor earth/power connections to starter.

    Test earth and power by adding a jump lead from battery terminals to starter pos and earth, this will rule it out quickly.

    I need to find another one this week.

    Will a Mk3 8v one fit ?

    I doubt its the starter, if the engine turn over when towed....... As the starter has absolutely nothing to do with that scenario.

    check the resistance of the earth to the body and battery it sounds like an earth fault. could be a wiring fault if it clicks it getting power double check wiring earths from gearbox and starter to battery crank is not siezed dont know if wd40 helped? if pistons had picked up your engine needs rebuilding! sounds like a wiring fault to me!

    put a second earth on it from the battery to the gear box
    i had the same with my 8v after doing a cluch change
    on mine the main beem light in the clocks would come on when trying the start it
    and you only got a clicking from the starter solenoid

    it's worth a try

    Just done my engine change 2 weeks back and we had the same problem. Just ran a long earth direct from car body earth near battery, to starter. All sorted when we did this.

    Wasn't this car being towed in gear and locking up?

    So it can't be the starter motor [:s]

    True but that sounds like a different issue to me. If it now turns over freely by hand, the clutch/flywheel assy is built up correctly then hopefully get the starter working and see if it cranks! Not sure what was meant by cleaning out the head though!!

    Should have stuck with the 8v!!!

    Hope you get it sorted.

    yes mk3 1.8-2.0 8v starters fit, but they have different trigger connection to mk2. you can remove the spade housing though from mk2 spade then it fits the mk3 terminal. once its running bring it back to me and i'll crimp you a mk3 terminal back on so you can fit a proper plug :thumbup:
