hey my father in law has just got a new car, ford escort 1.6 finesse. he picked the motor up drove 3 miles downt he road and it just cut out, called rac to help they said it could be something to do with having a blockage in the catolic converter/exhaust, after the rac man left he noticed a sticker on the visor saying it had a fuel cut off switch so he found that and pushed it. now it is starting but wont run he has felt the exhauset for cold spots n nothing it all hot, checked the lambda sensor, cleaner sark plusgs but cannot think off anything due to not really much about motors.

is their anyone who could halp on this situation?
