not start again

Hi can anyone tell me why vera not start when its been raining but when its dry she starts first time  :dontknow:
Thinking it maybe the coil getting wet?

I doubt it's the coil Jen, it's more likely to be the HT leads. The moisture in the air can cause them to arc if there are any small breaks or gaps in the insulation.

You won't be able to see the gaps but if you try to crank it over when it's dark you will see where they're arcing/tracking. Give it a go in the dark, if you see any tracking your best to buy a new set of leads (AVS Car Parts - [The VW - Audi - Seat - Skoda Parts Specialist] are fairly priced).

When I had this problem it was the ignition module getting wet (more like sitting in a pool of water!) as its in a stupid place in the scuttle/rain tray bit under the windscreen when you open the bonnet.

Might be worth unplugging the connector and drying/cleaning it and then spraying it with electrical sealant when its back together.

Ive not had a problem since Ive done that
