my friends 92 civic has a really hard time starting if he leaves it in the sun for over 2 hours, but it cranks right up at night or if its in his garage. Any of you know what the problem could be?

 

main relay possibly? I know on my wife's car the problem was worse when it was hot outside.

where is that located? hes in the military and dont have too much money, so he wants to know the problem b4 fixing it how can he tell?

 

main relay, i had the EXACT prob.

 

Main relay is under the dash on the drivers side. It's quite a ways up there. Here's how I do them. Slide the drivers seat all the way back, take a flash light and look up there. The relay you are after is roughly 2inches by 3 inches, by 2 inches. It will be bolted to the left side metal of the car. What I do is either unplug the main relay (if you are going to replace it) and the leave the old in there. Or if you want to fix it, unbolt the old one, pop the cover off, and look for the bad solder joint, and yes there will be one. re-solder it, and put it back in problem solved. If you need anymore help with this. PM me

thanks for the info. do you know where he
can pick a relay up at? and how much?

 

Main Fuel Relay is above the hood release inside the car - 10mm bolt if I remember correctly.

 

Should be able to get it online at Hondaautomotiveparts.com for around $50, but he should try to fix the old one first.

 

ok ill see what he wants to do. is it called main fuel relay or just main relay?
