I posted a little while back about starting problems with my 1.4petrol 2004 Fiesta. I'd put it down to using my sat nav, but I've now ruled that out.
Bascially what happens is that whenever I've been on a longish trip where the engine has been worked hard and then I leave the car for a few hours, or overnight, it will refuse to start again, I just get a grindnig noise whenever I turn the key. Once I bump start it, it will run fine and start again on the key no problem, until the next time I go on a longish trip.
95% of the time it starts without any dramas whatsoever, I mostly do journeys of 20 minutes or less. But whenever I've been out for a 'drive', it won't start the next day.
Any ideas?
It's being chucked at the garage next week anyway for another reason but I'd like some clue before it goes. I'm pretty sure it's not the battery, as I've replaced that and the problem remains. It's reading 12v with engine off and
14v with engine on so I don't think it's the alternator either. The only thing I can think of is something is not reacting well to the engine being hot then cold again?!
