I have a 2005 Focus Ghia 2 litre diesel owned from new. Just recently it has developed a starting problem. It seems to particularly occur after it has been parked for a few hours. When starting, the engine turns over perfectly, the engine fires but before tick-over can commence the engine dies. If I try again immediately afterwards, the engine just turns over without firing. I try this two or three times without success. After waiting several minutes (maybe five) and trying again the engine turns over quite a few times but then eventually fires and stays alive as I rev the engine. It then drives normally.
As I say, it's intermittent so when I ask my mechanic about it he says until it doesn't start at all, he'd be just guessing. Anyone had a similar issue and if they did what was the outcome? Thanks.
