In the Accord's there is only one relay that controls the fuel pump and fuel injectors, which IS the "Main Relay". Its not a general-purpose relay, its quite vehicle specific, so chances are the parts store wont have it in stock, but should be able to look it up and order it for you. But it is called a "Main Relay" and your car only has one of these, along with several other "general-purpose" relays (for A/C, headlights, ABS, etc.).
If your local parts store cant get it for you (or even look it up...
), then you can always just go to a honda dealership, find one online, or remove your main relay and fix the solder joints that always fail on them, I'm sure there's a DIY somewhere on this fine site 
On a second note you said "It starts sometimes and sometimes it just cranks for a long time... ". If a main relay is going bad, its usually not going to let the engine start while your cranking if its acting up. Normally you can just flip the key back and forth untill you hear the fuel pump kick in once the relay cools down, and then start it up. So are you saying that occasionally WHILE your cranking, it just takes a long time but will eventually start? Or, does it take a few individual tries of cranking before it starts?
Im just trying to make sure you are infact having a main-relay problem, and not some other fuel / sensor / or starting issue.ON_N20Nitrous = Been there. Turbo = Now. Nitrous + Turbo?... LOADING

I fought with a bad main efi relay for a few years. Cold weather it was fine. Hot weather with the windows up it would crank, pop once and then just crank. sometimes cycling the swith would help. other times just waiting a min or two. Finally got sick of it and got one from napa. On mine what I did was unhook the relay from the dash and just let it hang from the wires. Ran it like that for a few days and when ever it would act up just tapping it would get it to start. Pretty easy way to tell if thats the problem.

do yourself a favor. never visit the stores that i cannot mention by name, that you have previously visited.
they are the automotive equivalent of toy stores.
NAPA part numbers:
ECH AR727
or
ATM 1492901
youre welcome.....
mine acts up once or twice a week. i just give it a smack or two while cranking the engine and she fires right up.

Or, save yourself the cash, watch this video and fix it yourself. It's really easy.

re-soldering isnt a permenant fix. hot weather came back and im having problems again too. go buy a new one. maybe drill a few holes in the case just to be sure it breathes...Comment

If you re-solder it properly, it will be as good as new, as long as it wasn't actually damaged.
I just go to the junkyard and pick up a few. It's a pain in the ass, but I just keep swapping out. It's worked so far.
