1991 Honda Civic. Starter works, engine will not fire.

If you're not getting any spark, it may be the coil or the igniter, both of which are located inside the distributor.
If no fuel, you may have a problem with your main relay.

Your car engine needs 3 things to fire: 1)Fuel, 2)Oxygen, 3)Spark

Oxygen: Check to make sure you have a clean air filter
Spark: Check to make sure you are getting spark, you can pull off a spark plug wire and lay it next to the engine BLOCK while someone else cranks the engine and you can quickly see a spark
Fuel: There is not a quick and easy way to test this, so if the other two tests check out okay, then first try to replace your fuel filter and make sure your vacuum hoses are all connected.
