On a 264 add fuel accumulator to that list, but the problem could also be too much fuel, (cold start injector staying on, fuel distributor plenum stuck, frequency valve or frequency valve relay "freaking out"). As was said in previous posts, you're gonna need a book. Now this is going to be a little bit like playing "hot potato", but you could see if your plugs are fuel saturated after this 5 minute delay before attempting to restart, that way you can learn too little fuel? or too much fuel?
