Default how do i test a fuel pump? without taking it out

i have no spark, i dont see anything wrong with the distributor on the outside, but haven't taken it off to check it yet, and i haven't tested the coil either but if it's neither of those can someone tell me how to test the fuel pump

copied off another forum. Not sure if it's a good test but seems logical -

"pull out your injectors (if you have a fuel rail and 4 injectors (all 1.6 liter Honda Engines are MPFI, only 1.5 liter DX is DPFI - if you have a DX, try pulling out the whole throttle body which is connected with 4 nuts to the intake manifold)) with the rail still connected to them (and electrical connectors connected to them too), pointing them to somewhere that will not ignite the fuel once they (if they) squirt gas out, and have someone crank the car while you look if gas is squirting out. If the gas is not squirting out, you now know that your car is not starting due to not getting gas to the injectors. It might be caused by clogged fuel filter, clogged fuel lines, non-working fuel pump (make sure you check for Main Relay before you go out to buy a new pump, because Main Relay gives power to the fuel pump - if your Main Relay is not working fine, and you DON'T check it first - you might believe that your fuel pump is not working, and be amazed that your newly bought fuel pump is not working either, all because of a Main Relay) or no gas in the tank (a long shot, but hey...). If you are getting gas, then connect everything back (injectors into the intake manifold, or throttle body to the intake manifold) and go on checking for spark."

I would just turn the key to the "on" position and listen to see if i could hear the fuel pump turn on

you can either turn the key to on and listen to see if it turns on(it sounds like a short buzzing sound) and if so and still no fuel check your relay. Its under your drivers side dash attached to chassis. I had a problem with mine and my haynes manual helped alot
