Hi Im new here, just searched the forum and could not find any answers I just purchased a Focus 1.8TDi 2003, it has sat outside my house for 3 days, When I test drove it ( private sale) it started fine. Now after sitting outside for 3 days it was reluctant to start, when I turn the key the engine turns over, and it sounds like its firing for a second or so but does not start. It takes about 10 attempts before starting.....I let the glow plug light go out as per instructions, The battery seems ok, but it was disconnected for a month before I bought the car, during the recent cold weather. Does it seem like a glow plug problem? if so can I clean them? The engine starts ok when its warm.. Any ideas please?
