A member of our family is absolutely convinced it's the coil, like obsessed with it being the coil

Deffo sounds like the sender - I had to call the AA out for mine after changing everything above that I had in spares - he put spark plug testers on the plugs and found that they were intermittently sparking which explained why sometimes it would start fine and then nothing.

To rule it out might be worth putting a message out to see if someone local can swap their dizzy over - if it starts and runs fine you’ve found the problem.

Coil breakdown is slightly different in that you will usually start getting flat spots when putting your foot down - that and it usually gets hot to touch.

I would say from that statement ^^^ you need to replace the distributor wiring.

I had similar symptoms on my old bus, turned out to be an intermittent short that sometimes spiked the ecu, sometimes wouldn't start, sometimes ran for days.

Van still not starting. I replaced the ignition control module, I started the van and it ran for about a second then cut out. I then tried again and it turned over but would not start, we then had an almighty load bang as it backfired :rofl could it be the coil or like mentioned the hall sender. We have our mot in a week so I really want to get it running

You need a time when its not starting so you can diagnose.

In order I would:

Check you have 12v at the coil - no 12v is dodgy wiring, or knackered ignition switch

Check the hall sender (as above, by earthing middle pin) - no spark is coil related, spark means the hall sensor knackered, or the wiring from it is.

Check resistance of coil - it might be knackered even if it measures fine. Coil might give misfires etc and make starting harder, but less likely to give you this on/off type issue.

Van is running agin :ok I replaced the ignition moduel but it still would not start. We went to see our mecahnic and he said the timing was out so he set that. He then swapped over the dizzy cap and put on a new rotor arm, he said ours looked a bit worn. It started first try and has been running perfectly. He said the moduel was probably the original problem but because I had been messing with the dizzy I must have messed up the timing :rofl so basically I would never have got it to go. He did spend time showing me how to find TDC and only charged us for the new dizzy cap and arm and not for his time which was an hour and a half. Can't complain there

That's great news - always worth carrying rotor's and dizzy caps in your batch of spares.

I orderd a spare dizzy cap and rotor arm :ok and a new moduel as it was only £18. So far we have had no problems

My 1.9 petrol engine seems to eat rotor arms. I suspect it is due to condensation forming in the distributor cap when not used much over winter.

Having similar issues when hot / restarting when hot.

Can anyone describe what a worm out cap and rotor arm looks like? Or is it hard to tell good from old/worn?

Scorch marks, deposits on the inside of the cap can be cleaned up with some emery paper, check for cracks etc. For what they cost i would just replace them with new if you have suspicions. Take the old rotor off put a bit of oil on the felt pad in the dizzy and see if there’s an improvement. I had a limited rotor but have since swapped to the more basic one.
