Intermittent no start 91 SI

[mattswabb]

I have a 91 civic si with a b18 swap. Today it wouldn't start, it cranked. Then it started then not again. I remember being told that these years had problems in the heat and that a relay sticks. It was 95 today. After a short rain the temp dropped it fired right up.

Anyone know if what I was told is true and what relay is the problem?

thanks in advance

the main relay is the problem most likely..
its not a specofoc temp,,but heating up cooling down and so on wears out the solder in the relay..just get a new one and it should solve the problem

Get a new main relay or if your good with a soldering iron do a search for how to fix your main relay.
