Hi guys,
I'm after some advice regarding what could be causing the starting issues im having with my mk5 escort 1.8 130ps at the moment. sometimes it starts fine but other times just turns over even if it has been run for say 15mins and left while putting fuel in, it wont restart without a struggle. its had a starter alternator and battery recently so its getting good spark and fuel so any ideas what to look at ?
cheers
