Sorry but I can't help this,

It's "pointless" trying to clean HT parts,

fit a new cap rotor and leads.

And for all you younglings out there it's electronic ignition so there are no points!!

Could be amplifier on side of distributor held on with two screws-probably simplest is a used distributor from breaker.

If you have a spark at the ignition coil lead then the ignition module won't be the problem. If there's no spark at the spark plugs the most likely cause is a faulty rotor arm. The spark will be tracking through it directly to earth. Change the distributor cap and rotor arm together.

If this is a 1.3 Cvh engine,then the cap and rotor arm will be the same for either Fiesta or Escort with a Bosch dizzy. Take a look at your rotor arm,if it an original Bosch part,it will have a part # stamped on the body..

The 1.1 and 1.3 ohv (valencia /kent engine)are basically the same .motor-car.net/ford-engines/item/16095-kent-valenci...e

They are a push fit. Sometimes, if the rotor arm hasn't been removed for a long time, it can "corrode" onto the distributor shaft but I've always managed to get them off eventually.

You just need to pull a bit harder!

Do remember that the ignition leads are resistive to reduce RF interference, or, at least, they should be. If you're trying to test them with a multimeter they will have a fairly high resistance.

On some Bosch dizzys ,the rotor arm was glued onto the shaft ,out the factory. You may well have to break off the old rotor. Also ,a Bosch rotor very often has a resistor built into the top of the arm,between the centre and tip.If the meter you are using is not set to read the correct resistance range,it will show no continuity.
