my 94 civic dx sometime won't start when it's hot. When it's cold, it can start easily. I bought a new distributor from auto zone. I change my fuel filter and fuel pump already and it still won't start when hot. I think its my main relay or some relays in my car. What can this be?

 

check your main relay

How are you suppose to check my main relay?

 

you also might want to check your timing. if your timing is off just a little bit to much you car will not start when it gets hot. i had this problem and my timing was like 12 degrees off my car was running like **** too

 

my timing is perfect. I check it using a timing gun.

 

Next time it doesn't start, open both doors and let it cool down in the interior for about 10 min. Sounds ghetto but try it. If it works, your main relay is the culprit. This is not a dead on test obviously, just a little something that works a lot of times.

Chances are it's your main relay anyway. Under the dash toward the drivers kick panal. Do a search and you'll see more about it.
