My pcV had a big problem right after ai washed it once. I would check that if the plugs look fine. Also there was another member last week who had a small wire disconnected from the bottom of the box where the plug wires come from.

 

One more thing, if you've disconnected your fuel line since last start for whatever reason, check and make sure it's fully connected. I pulled mine off once and put it back on, crank but would not start. I just didn't connect it all the way, I pushed it up, it stayed, but it wanted another 1/8 inch up to lock it on.
