Engine cut out

Sunroof drains blocking are common. Not the hoses, but the rubber bladders at the bottom.
Lift the hoses out of the rubber at the bottom and run some wire clean through the bladder to make sure it properly clears all the crap out.

that was a fast reply lol.
Can you easily get to those bladders or do I have to remove the bumper?

No need to remove anything from outside/underneath, all easily accessible. You need to remove or peel back the boot side linings though, to access the hoses/top of the bladders.

Right well update today. Checked the drain bungs again today after all the rain yesterday the boot was wet at the side by the bungs. I removed the pipe and cleaned with a big pipe cleaner type thing. It was indeed very blcked.
When I went over to the drivers side it felt really blocked so I gave it. Good shove and bust through the side of it lol duh.
Maybe it was already split? I'm not sure so for now I've extended the drain pipe with some hose which is attached and sealed to a bottle in the boot. Until I can order a new bung.

So hopefully this has cured it. The weather has be nice here all day bit windy but very dry and not to cold so I've had the boot (stripped) with seat down, all doors opens and sun roof open too, in hoping to dry out the interior. I always vacuumed the hole car maybe that'll help maybe not lol.

So fingers crossed I've sorted this issue.

Oh yes I also fitted my new earth cable that came today so that sorted. Talk for a spin and she was fine, I really upset some kiddy in his mk4 golf gti

Although the eml came back on and is reding egr again. I guess I'll have to clean the hole chamber out. The car was fine though no hesitate or misfiring.

Cut the bloody bladder things of the end off the drain tubes, or cut a v so there open. Was a common Honda fix for the old mk2 CRX. They used to block up and leak for a past time

Any ideas what the bladders are for?? I've got several Hondas with sunroofs, all with soaking boots! I don't mind chopping the bladders up/removing them, but presumably there's a reason for them being fitted?

TBH I don't know, nor does my Forman!

! I presume they are to stop water going back up the pipe for some reason. But we just cut them up/take them off. Don't get me wrong tho, they may not be the cause of water leaks, but that's where I'd start. My aerodeck was leaking like a sive and that was cracked gutters/roof rail anchor points!!

. My lude leaks but not bothering finding it just yet

EDIT : actually I think there to seal the tube from outside, so water doesn't get inside the car past the side of the tube. Just cut them!!

The bladders are a very simple one way valve, there to stop air pressure blowing water back up the pipe. Common on drain tubes on all sorts of industrial equipment.
