My Escort Estate (petrol, 1.6L injection, year = 2000) starts first time (and runs) fine except under one condition. If I start the car and run it for a few minutes (eg, to change the car's position on the driveway), switch off and leave it for a day, the next day it won't start and I have to use the "flooded engine" technique mentioned in the owners handbook. This has happened on two occasions now so I assume I'm doing something wrong. (This never used to happen on manual choke cars, or manual choke conversion cars, in the olden days!!!!) Should I be switching off with the gas pedal in a different position, or revving up before switching off (something that was frowned upon in the olden days) or what? Or it this symptomatic of an injector problem?
