my timing belt broke i put a new one on and it is not firing on plugs 2 and 4 ? what could be the problem?

 

Did you bother checking to see if you had any damage? The F series is an interference engine and as such the valves can be majorly hosed in the event of a timing belt break. And with that said it sounds like it wasn't in the best of maintenance. What else have you changed out?

There is an FAQ guide on how to do a timing belt change in the F22, I suggest you start by reading that.

 

did u check the alignments?, did u install it correctly?

 

re-check timing and then compression test for bent valve. ^ interference engine.
