Hm yes, where to start. COuld be many things. I've only just recently been through the same thing as my car gave up the return journey from Dover to Wales, Managed to get to Bristol and had to be towed home for the remainder of the journey. Anyway...
Have you got a Bentley manual or a haynes? It describes a few points where you can test if voltage is getting to the various components in the ignition system to find out if you have a break anywhere.
Likely causes could be: Hall sender in distibutor (this is what had gone in mine), Ignition module (you have changed that though), Coil, main HT lead is broken, Ignition switch behind barrel, distribuor cap has a tear and not making contact, distributor not turning (roll pin has popped out). cable breaks.
Few basic things you could test like, does the distributor turn when you crank the engine?
Do all the HT leads look ok? If you have a voltage meter measure the ohm values and checkfor continuity.
Take a look at the DIstributor cap and the rotor arm, are they damaged, contacts ok, any cracks?
Take a HT lead of a spark plug, take a spare spark and put it on the lead. Wear insulated rubber gloves or insulated handle on some grips, hold the thread of the spark plug on the engine and check for spark. Do the same for the main HT lead (middle).
Otherwise perform voltage tests on all cables and check for continuity.
Oh, and welcome to the forum
