More problems... non-starter and cutting out.

[darrsi]

Just read your original post again, i don't s'pose you've had your tank up, or off, at all and perhaps kinked a fuel pipe?
And are you getting the clicking noise of the fuel pump when ignition is turned on?
I'm wondering if it's fuel starvation?
Doubt very much if it's the actual plugs, a clean up and checking the gaps will probably be okay for them.
