hey all, ive not long got a fiesta rs turbo, been running fine but other night while driving it just cut out and wuldnt start again, i got out and checked to see if it was getting spark but nothing. ive chaged the coil pack, leads plugs and crank sensor.

ive re set ecu/chip by removing positive from bat for twenty mins but still not firing.

can someone please point me in right direction with what to try next?

cheers very much
