94 Accord EX starting problem

My '94 Accord EX is in good tune and runs perfectly. However if left parked in direct sunlight for any length of time, it will not start. It turns over fine but will not start. If left in the shade it always starts right up.
Any suggestions??????? Thanks,

You need to replace the main relay. The soudering goes bad over time. With parts and labor it is about $75 or you can try and resouder (or replace) it yourself. Check this website: http://www.fourthgenhatch.com/mainrelay.html

my 93 accord did the same thing this summer, & now it just won't start. I guess I'll try replacing that part & see what happens
