Right my fiesta turbo has decided to stop sparking, it cut out when i was driving home the other night. I have recently raised the boost to 15psi, and when you try and hold the power down it was cutting out. Now it wont spark.
Ive changed the coil pack, and the cps sensor but still luck.

Could it be the ecu maybe, im not sure if its standard or not so could that be whats cut the spark out?????

Any help will be appreciated.
