Fiesta Mk6 Zetec S 1.6 straight engine swap
 

Hi,

Hoping someone could help me with some advice.
We had to do a straight swap with boyfriends 1.6 fiesta zetec s engine.
We've swapped the engine with the same version.
Everything else like clutch, fly wheel and timing belt has been changed.
Now however the car won't start.. It cranks over but no start.
There is a spark and there is fuel getting to the engine. However looks as though no power getting to the throttle body.. When you press accelerator nothing happens.. Could this be a pcm code causing this? Or some sort of safety feature stopping the car from starting due to the engine change??
We are desperate for help..

Thanks

Louise
