1994 accord EX.

Car has been running a little "off", sort of a chug when the engine gets warm. When it does this sometimes when i cut the car off to go into somewhere the car will not start when i go to restart it. theres seems to be no rhyme or reason to when this happens. It appears to be trying to turn over, but acts like its not getting any gas. if you wait 10-20 minutes it starts up with no problem, and runs smoothly. If you open the pressure check valve when it is dead, there is usually no fuel coming from the release.

I've checked and replaced the water temperature control under the distributor, as i've seen plenty of posts saying that can be the culprit (and in doing so also fixed an oil leak behind the distributor). I've replaced the cap and rotor, plugs and wires. Just replaced the fuel pump this weekend.

Any ideas?

 

If you replaced the fuel pump my next thought would be the fuel pump relay.
