    The car cuts out and the engine light comes on, then the engine light might stay on for a day and turns off automatically. Happens about once a week.

    What website did you get that off?

    Its like the fuel pressure regulator is sticking and not doing what the ecu requires.
    The pumps are awkward to get to as the are in behind the timing belt and will require removing the scuttle panel..wipers etc to gain access.
    I'll see if i can find some info later..:)

    This is the fault description for the Dv4 engine.
    The first thing to do is replace the fuel filter if i has'nt been replaced in the last 10k or so.
    After that you will need someone with good diagnostic equipment to see how the pressure regulator is behaving.
