    That f$%$#@g high pressure fuel pump on the Z22YH ... $36 to fix

    Update .. I tried to get the end cap off but it would budge. Have since discovered a video in Greek? .. that shows its held by a circlip. No wonder it wouldn't budge. At 12:09 here. If I do this again , the kit contains the rubber cap so ill fill it that way.

    Z22YH Possible Z22yh fuel pump alternative.

    So I've seen mention of an alternative replacement of the z22yh fuel pump mentioned on a couple of sites. I hadn't given it much thought because I don't need one but thought I might put this here so other might pick it up. So I found this page from a Russian guy with, what I assume, is a test...

    Z22SE carb cleaning piston rings

    Not sure about putting it in the oil , but go and google outboard carbon cleaner. There's whole bunch of products used by outboard engines to specifically tackle carbon build ups. I've used the yamaha products with great success.

    Z22SE carb cleaning piston rings

    Subaru make, and recommend, and upper cylinder cleaner. Recommended usage is every other service. I've used it before with old plugs and they come out sparklingly clean. Just unload the can into a running engine. Be aware if you use it during the day the neighbours will think your house is on...

    Z22YH Where does this connector go

    I don't think that's it. The cable is too short and the wrong shape. Ive got the cable for the CTS coming from round the front and plugged in as per this pic (not my picture but same engine)

    Z22YH Where does this connector go

    So we but the Astra back together but its not starting and the fan is coming on immediately. Its throwing a coolant sensor error as well. I suspect the coolant error is something to do with this 'spare' plug but for the life of us we cant figure where it goes. Anybody got any ideas.
