My bet is that its flooded. Running a car for a few seconds from cold (any car - even a brand new one) will leave it very prone to flooding. best bet is to throw a new set in (any that fit will do, its only to get it started) failing that, cook em with a blow torch then try again.
It may also be that the ignition system isnt 100% and giving a weak spark, thus adding to the flooding issue, check/replace cap/arm etc etc.

if it aint that...fuck knows! lol
