aright guys
i hav just had to fit a new 1.25 (couldn,t insure bigger ) in my mk4 fiesta. everything is working good but im not getting a spark.
we have checked the voltage and its all correct appart from the wire into the coilpack which is reading around 8 volts.
we have tried a new cps but still no luck.
we think it might be because we have used the old fly wheel off origonal engine (1998 new one 2000) other thought is that i might need a new ecu.

CAN SOMEONE PLEASE HELP !!!!

cheers
