99 accord having problems starting the car
I recently purhcased a 99 accord 2dr ex v6.The problem is when i go to start the car it turns over but does not start.I'm thinking it might be the relay or ignition switch but having trouble pinpointing the source of my problem.what is a way for me to test the relay and ignition switch so i can fix this problem right away.

First thing I would do is check fuel pressure. If no pressure check fuel pump. If fuel pump works check regulator.

Sounds like pressure regulator. Mine was replaced already on a 2003V6. It was doing the same thing. It would turn over forever before it would start.

You need a multi-meter & a circuit drawing.
But first, you can listen for the pump to run for 1 or 2 seconds when you first turn the key 'ON' (not 'start'). That sorta verifies the whole system. If that's OK, then you can check whether you have spark.
If it's not OK you can go back to the pump & see whether it's getting battery voltage during that 1-second priming. If it IS, then you got a bad pump.
If there's no power back there, you gotta find out where the circuit's broke. Verify there's battery voltage at the hot lead going into the ignition switch. Then with the switch unplugged from the harness, check continuity thru each of the 4 circuits thru that switch, at the proper switch positions. There's a good explanation for that check in the Helm book.
If that's OK, then you go to the next point 'downstream' in the circuit, the main relay. There's a similar procedure to check it. Then if it's OK, you check for breaks in the power wire going back to the pump itself.
