    weird happening at the high flow pump

    I filled up yesterday at the local Shell/Coles in mt 2002 EU3 auto with 140KK.
    As I was pouring some diesel conditioner in, someone took the low flow pump, and I had to use the high flow pump.

    My low fuel light had just come on and the tank took 77 litres so was not really empty.

    When I went to restart , the car would not start, just turn over quickly as I have brand new batteries , and the voltage would have been full.
    Checked Nanocom on the spot , and no faults.

    I then tried priming with ignition off and on, and on the fourth prime she kicked for a second so I kept going and on the fifth prime away she went, thank goodness.
    Has anyone else had this happen?
    My guess is that the foaming associated with high flow pumps may have caused some air to get into the fuel lines but the car has never ever taken more than a nanosecond to start previously .
    Any experiences / ideas of another cause.?
    Regards Philip A
    PS don't think it was crank sensor or any other sensor for that matter as nanocom was used after the first three attempts. Is there a low fuel pressure sensor?

    I can't see the foaming causing a problem. The foam is on top and the fuel pickup is near the bottom of the tank.

    I have to use hi-flow bowsers quite often and have never had that problem. With the filler neck on the tray top having only a little slope, I really notice the foam. It takes ages to get the last few litres in.

    May not have had anything to do with the high flow pump. Mine has done something similar twice outside the telephone exchange. I think there may be some electrical interference that confuses the electronics. Engine spins over but won't fire. 1st time the same as you- tried about 5 times and eventually started. Second time just locked and and unlocked it with the fob and away we went. I just treat it as another landy thing
