    Z20LET Probs... Please Help its xmas! ;)

    Hey,

    I'm outside in the freezin cold trying to get my motor working again!

    First of all, i'm having similar probs to essexaaron, like in below thread
    http://www.astraownersclub.com/vb/sh...d.php?t=228776

    However, I havent checked my injectors as i dont know how to get them out , anyone help with getting them out? I also disconnected the bolts at the end of the fuel rail and fuel drips out of them easily.

    Secondly, I have checked the plugs too. There appears to be a bit of oil in the 2nd sparkplug well. The other 3 are clean as a whistle. Would this be causing problems ie not allowing it to start? I also put some plugs in the coil pack, stood it on its back with plugs in the air and turned the car over but couldnt see a spark! What am I doing wrong?! I tried the coilpack on a mates z20let and it worked fine.

    cheers and merry xmas

    You need to ground the plug's, have the ends sitting against something that's grounded.

    To remove the fuel injectors you will need to remove the fuel feed and return lines, which will be pressurised if the ignition has been on recently so slacken slowly. then unbolt the rail from the manifold and disconnect the electrics. If you are lucky you will be able to prise the rail and injectors off in one unit. If its too stiff dont force it as you will force the injector to pop of the rail and you may damage it. Disconnect the clip holding the injector to the rail and remove separately.

    The oil in 2 shouldnt be a prob unless the plug was slack.

    In order to get the plugs to spark when attached to the coil pack the need to be earthed. The best thing to do is stand the plugs on a metal part of the engine (not the cam cover) not easy with four plugs at once.

    cheers guys, will try to ground them now.

    as for the plugs... no.2 well wasnt that bad, but wells 3 & 4 didnt seem that much but upon takin the plugs out, they were completely covered in oil right down the thread but none on the spark end itself.

    WRT the injectors, how do i remove the black plastic bar that the wires run through?

    i feel like a complete mong!

    I'm trying to whittle down the options to find out the problem of why my motor wont start!!!

    You need to unclip the top cover on it mate, have a good look at it and you'll see the wee lug clip's

    Once that's off lift the loom out and you'll see the injector plug's, remove them, i'm not sure if any screw's hold the cover down or if it's clipped to the rail but have a look and all should become clear.

    Don't get the injector plug's mixed up!

    Your rocker cover gasket is proberly leaking thats why you are getting oil in the plugs. cheap and easy enough to replace.

    cheers mate, I will take off the rocker cover and replace the seal as well as putting some silicone in.
