ona crx the main relay is right under the coin tray....like behind it in the dash. last night mine wigged out on me. its a common problem what ive heard. i have these same problems. i too am getting a new 'revised' realay from the dealership. they are delaership only items...about 40 bucks or so. but yeah this was my problem with starting. last night it was stuck in the click position...you know the click click start sound when you start it...well it was one the click and stuck. i looked forever to find the buzz sound and yeah sure enough, main relay. i hit it a few times and wiggled it then the buzz went away and it finished it click..havent had any problems so far today but i am still gonna replace that little slut. its definately on its laast leg.
