Ford Fiesta Style Not Starting when warm

George72 · 2 Jan 2022 at 14:58

I have a ford fiesta mk6 style petrol 1249cc 57 plate
Goes really well but will not start always when warm it seems intermittent .
Will start if bump started
Have changed fuel filter air filter and plugs.
Been put on problem fault finder but no faulty codes coming up .
Leave for 5 minutes or so go back and it will start
Anybody have had similar problems or have any idea how to fix it or what to try next please ? Thank

Does it turn over at all, or does it just refuse to do anything when it acts up?

George72 · 2 Jan 2022 at 22:43

Turns over but won't fire up do you think it may be spark plug leads as it started not long after I changed the air filter I may have disturbed the the leads a bit . Thanks

I'd look at coilpacks/leads, assuming you've already checked fuel side

George72 · 3 Jan 2022 at 18:49

That's the next thing I think done the plugs and fuel filter. Think I may have disturbed some thing when I changed the air filter like the plug leads may be they become brittle with age . Thanks for your reply

start with cheapest first. unless your loaded in which case change engine first then if it doesn't start try a new battery,.

UPDATE After all the hassle took it to garage they thought it was the crank sensor at first but in the end it was a faulty Battery .
Sounds a bit strange but they assured me it was the Battery. So will order a battery tonight

Thanks to all of you that gave me helpful advise many thanks

I would have gone crank shaft sensor as well if I'm honest.

But yes amazing the amount of issues that can be caused by a bad battery. Similar to having a bad PSU on a PC I guess.
