Had the plugs out, not wet as such but a bit damp and smelt of fuel - I had been turning the car over so they were no more damp than I'd expect. Gave them a clean and put back. It did fire and run for literally a second when I held my foot to the floor before taking plugs out, but then cut out.

Haven't tried checking for spark on all plugs, just one.

I've got a voltmeter but wouldn't know where to check and for what voltage if I'm honest, electrics aren't exactly my strong point!

Running out of light do it seems like the eufe's going to be stuck indoors with the kids tomorrow!
