I have a 88 Integra with the following problem, it is a tough one.

When I would start the engine cold or normal running engine temp it would sometimes initially start but it wouldn't totally start, like it would sputter, I would try to feather the throttle but before you knew it the engine stopped. I would again try to start it again but it do the same thing. I would wait a few minutes and it would start right up like a champ or sometimes not. It would do this every three months or so. Now it is doing the same thing except now after a few intial trys it won't start at all, it just cranks but if I wait one hours or 4 hours and try it again it starts right up. I have checked to see if its getting spark when it fails to start at all and there is spark and I smell gas. What the HELL can it be? Any ideas?
