its a mk5 fiesta 2001 with a 1992 xr2i 1.8 engine.
yes plugged the coil pack in properly
the coil pack is just a motor factors one but i only bought it yesterday to make sure it wasnt that.

i have removed the cps and refitted it but how could i tell it was that? and would this all of a sudden just go or would it slowly brake causing problems on and off? as car was runing fine until it all of a sudden refused to start
