    The time has come to get her running again ;-)

    Hello All from sunny England ;-)

    I have a 500T that has stood for a few years that I'm about to restore to full health!

    I played with her a few years back and, apart from a sticking wastegate, she was running fine. I've drained and put fresh fuel in the tank, there's a spark
    and good fuel pressure but she won't run. In the interest of tracking down the problem, I gave her a good squirt of Ether down the intake and she fires no problem.
    I'm guessing this means the ignition side of things are OK, and it's a gas related problem I'm looking for.

    It's showing an intermittent "Fuel System" fault which I tracked through the codes last time to the crank sensor. I replaced these, along with the w/pump mechanical seal. Am I
    correct in thinking this must be working OK as it'll fire on Ether?

    I'm currently thinking that the injectors are gummed up after standing for a long time, are these an easy clean up job or is replacement time?

    Going to change all of the fuel lines today and give everything a good clean. Any pointers would be much appreciated!

    Could somebody please post a link to the w/shop manual as I've searched and can't find it ;-)

    Thanks all!

    I'm thinkin you're onthe right track from air in sys.

    to pressure to injectors.

    Now this is my opinion doubt 2

    injectors are blocked completely,

    if I M way off track someone will

    jump in any minute now.

    But didn't sound the same.

    Injectors can be cleaned by removing and soaking in a good solvent that is rubber compatible.
    You can then test them by using a 9v battery to trigger the valve inside to make sure that it is opening.
    Or, you can just send them out for professional cleaning.

    I might be wrong, but I don't think we have a FSM version for the turbo's in the WIKI yet, at least not that I can find.
    May the myriad of wheels in your head, keep the two wheels between your legs rubber side down.

    Thanks all! Can't find the Turbo manual in the Wiki link. I'll plough on and give the fuel system a good clean out. Guessing injectors will be OK in an ultrasonic cleaner?

    Yes.
    Just be careful that the top section with the electrical connectors does not get wet.

    I wouldn't bother trying to clean 35 year old injectors myself, they are bound to be needing a good rebuild. In the US it is about $25 to have them rebuilt and tested. I use Deatschwerks, I'm sure there are similar shops close to where you live.
