Ford KA no spark

Car: Ford KA
Variant: 1.3
Model Year: 1998
Categories: Engine & Drivetrain
my mums ka began to run on 3 cylinders, so ive changed the spark plugs, new ht leads, and a new coil, and its still running on 3 cylinders

no 4 is where the problem is, there is no spark at all coming through the ht lead to the plug.

i thought at 1st that i had bought a duff coil, so went and changed and replaced and still no change

any ideas? any body had a problem like this before

thanks...

swop ht leads between 1 and 4 to see if no 4 cylinder works as this car fires 1-4 togther and 2-3 togther called wasted spark.if no.4 cylinder ok and no.1 fails it can only be electrical and you may have a problem with coil or lead cant be anything else
