Fuel filter and HT leads?
Is it idling smoothly or is it a bit rough?
Have you tried putting a code reader on it to see if anything has been registered?
March 6, 2012, 10:02 am
its not even starting now, but there is a spark
put a reader into it but comes up with different problems e.g IMRC,malfunction to fuel rail but that has replaced.
maybe its the crank sensor breaking down?

I know injector issues are mostly common on the mondeo TDCI's but this sound like a tdci injector issue so is it possible your injectors are knackered?
