    Default DS23 74 Injection problem........FIXED

    Done, it took me a whole year, but I cornered the [email protected]#$%^&.

    The guilty part was the pressure regulator. I avoided it like the plague for a long time because the bugger was nigh impossible to get to.
    I finally removed it and wasn't able to re-install in the same spot , so did a bit of re-engineering myself, and presto the D now starts, idles and behaves.

    So....for anyone with insolvable injection problems: I suggest:

    New pump, new plugs, new pressure regulator.

    Be prepared to loose skin, blood and hope, but in the end.....it works!

    The original fuel pressure regulator is adjustable. Do you think someone might have messed with it's settings When the regulator died on my CX it's pegged my pressure gauge against the back of the "0psi" stop.... Wow, I drove it home from QLD like that how did it not burst a fuel hose and burn the car

    No I don't think so. Probably died of old age? But I must've made it worse when I installed a brand new fuel pump last year. The symptoms progressively got worse.

    Now, next week is reserved for an oil change as I am sure there must be half a litre of fuel in the oil by now,..... and that can't be good.

    Good to hear it's running now. I've had the fuel in the oil problem too! Yes, a god idea to change it if it's been flooding and misfiring a lot.

    If you plan to leave the regulator in that position, secure it to the manifold so it can't move around. There's also meant to be a clip securing the inlet pipe on the front half of the fuel rail to a bracket on the front of the head. It's under the hose going to the heater.

    Started fine, ran for a few minutes, then started coughing, at the same time, horrid smelling black smoke would come out the exhaust, then died. Couldn't restart for a while. But after 15 minutes, could restart and start the whole cycle again........
