    if the rubber seal is in the wrong position you will not get it down, place the pump in position and ensure the seal is low enough....use your fingers....to contact the seal ring and it should go down low enough to start the thread on the locking ring.
    there is a pictorial in here somewhere....a search (hahaha) might find it.

    Oh! Also, when I replaced mine, the new pump had a tab on the side at the top - the old pump didn't have this. The new pump wouldn't seat at all until I cut the tab off. Just compare your pumps to see if thats the problem.

    Thanks again for replies guys. I wondered if I had seated the seal correctly, and it looked OK in the faiding light yesterday but will have another look this afternoon. Off to a wedding this morning - must be 10/10/10.

    Think I'll try the block of wood trick too - thanks Blknight.

    Will post of my success tonight!!

    How true. Seams the seal was not seated correctly and after fixing that I had the locking ring on in under a minute.

    Unfortunately I flattened the battery in previous starting attempts and there wasn't enough juice to start it. The pump definitely works so we should be good to go tomorrow after a night on the charger.

    Thanks again

    Before trying to start the engine, also make sure you've done priming sequence (ignition on & press accel pedal half a dozen times) about 5-6 times to make sure the engine has got fuel.

    I'm pretty sure on the D2 at least you turn the ignition on which will activate the fuel pump. Wait until the fuel pump times out. Do this 3 times. This brings fuel up to the engine and purges any air.

    Accelerator on the floor and crank engine for no longer than 30 secs at a time. The accelerator action lets the ECU you are starting with a purged engine and to let the fuel through the injectors. Once the engine gets to 600rpm I think it was then you let off the accelerator.

    Tapping the accelerator tells the ECU to go into extended purge, which runs the pump for a couple of minutes at a go, instead of the usual 30 seconds.

    When I did it, the fuel level was low, but so long as the pickup is submerged, I can't see how the level would affect how long it would take.

    Yeah, the flat-to-the-floor when starting is the other half of it which I couldn't remember of the top of my head.

    The owner's handbook has the exact details (for the whole lot) in it.
    What I wrote was the simple version I remembered from when I had to do it a few months ago.
