First, of all eliminate the easiest...ie put some fuel in it...
Second, the overfueled plug and missing when first running sounds like your cold start injector is on it's way, once it finally packs up, starting is VERY difficult.
And if you is a bit fik like wot I was earlier this year you'll replace/rebuild
everything else(luckily I've 2 spare cars in my spares dept)before replacing
it/takes about 20 mins. Good Luck
