starting problems

[macdman]

so on the days that are getting hot, my 1993 integra wont start. or it will start and than die and wont start. my temp gauge reads normal. but on other days i have to let it sit just for it to crank. idk what the problem is. maybe its my starter but i have no idea what the problem could be

On really hot days my 91 would do the same thing(and there are a lot of those here in Tx). It turned out to be the main relay.
Is it just not doing anything or is it trying to turn over but not catching?

 

[macdman]

it does both. depends on the day. some days it wont do anything but other it will crank but not start. if i just let it sit for a while it will start but just depends

I think it shoud be related to sparks or gas pump.
