We "broke down" in the car park at Digley reservoir in Yorkshire near Holmfirth. We'd been for a walk, kids got a bit dirty so we opened car up and got them changed. Had an ice cream and then tried to start car. Nothing. Called out RAC, who after sending a patrol to the south coast eventually turned up four hours and eight or nine irate phone calls later. Patrolman immediately diagnosed out of fuel, I said I found that hard to believe as car was fine when we parked. How unlucky would you have to be to run out as you switch the engine off. To prove he was right he pulled off the intake hose to the throttle body and sprayed Bradex directly into throttle bottle whilst I operated the ignition. She started and ran on the Bradex, "proving" his point. We fetched fuel put it in and tried again, in the meantime my wife had waited with the kids and the car, she'd obviously operated the remote locks. Needless to say when we'd fuelled her up she ran like a dream! We thought there must be a fuel sender issue, but I've just worked it out. Flash to bang period you could measure with a calendar! The immobiliser cuts the fuel circuit, but not the ignition! So there was still fuel in her, but the fuel pump was cut out by the immobiliser because we'd opened the car and not operated the ignition..... Told you it was embarrassing, my only excuse is we'd only had the car a week and hadn't read the manuals. It was only by this very set of symptoms happening again on a known full tank that I realised what was going on! DOH! The RAC however have no excuse..... Al
