Starting Problem
I have a 98 Accord 4cyl non vtec. It will start and run fine when its cold, but when its warm it will just crank. I know it has a spark and fuel because i replaced the coil, distributor, fuel pump, fuel filter. Please help

Diagnose before throwing parts at the problem.
Have you checked for engine codes?
When the car is not starting, turn the key to the II position, but do not try to start the car. Do you hear the fuel pump turn on for about two seconds when the check engine light does the bulb check? It is a faint buzzing/whirling sound that comes from the back seat, so turn off the radio, blower, etc and listen carefully.

Try spraying starter fluid & see whether it fires up for a second or 2. That can point either to lack of fuel vs. lack of spark.
I know you said you have fuel & spark, because you replaced all that stuff. Even though you hear the fuel pump running, that doesn't prove the injectors are actually firing and delivering fuel into the engine.
You need Air, Fuel, Compression & Spark. Air & compression are almost always OK especially because it'll start when it's cold.

Spark is easier to verify compared to fuel. If you have a spark tester, connect it, then see if you have a spark when the car is not starting. A timing light is another way to check for spark, if the light flashes when you try to start the car. If spark is missing, you can work backwards.
