Been asked to look at a mates escort cab with a fiesta turbo engine in. Car wont start because there is no spark but there is fuel. Believe he has put new plugs and leads in it but thats all. At a guess id say one of the sensors but is there anything else i should be looking at thats common. Is there anyway of checking sensors with a multi meter and what sort of readings should i expect to see. Any help would be much appreciated.
