    This starts first time with a short tow. Runs well. Leave for about an hour then non start. Another mechanic was on it and said there was no power to the pump. I had a look and hooked up my power probe to pump and the pump worked. Did not start but found that the mechanic had fitted another filter and tried to start without bleeding, then the battery went flat. One of these day's. Looked again today and tow started. Stopped and left for a few hours and checked for power with ign on. Pump ran for three seconds. Turned over and there was power to pump and started. Will try again tomorrow and hope that it will not start so I can be nearer in getting a fix. There is a black relay next to the ecm which stops power getting to pump when turning over and pull out when running the engine stops. This does not make sense when looking at AD wiring as there seems to be two relays but can only find one.
    Cheers Les
