Hello

If there’s 12V at the coilpack but no spark then check the ECU power supply (fuse and relay) and also the connections to the crankshaft speed sensor inside the distributor

You can test if the crank sensor is OK with an AC voltmeter - measure across the the two pins whilst cranking and you shoud get a positive voltage

Also the distributor caps can suffer from a build up of white oxide which doesn't help the spark so try removing the cap and give the contacts a scrape with a screwdriver or similar and then a good clean out

Check the resistance of the spark plug leads ( 13-15Kohm / metre) and replace if any doubt or high resistance - Also replace the spark plugs if any of them fail this checklist:
