It used to be touch and go but suddenly it couldn't start without cranking for at least 3-4 times when the car is cool down after an hour or two. It feel like there's no spark/fuel during the first 2-3 cranking.
I replaced fuel filter, spark plugs, and change the distributor in the garage but it still doesn't work. Idle was rough and shaking. Highway was alright.

I really need some help here.
