Help!! Got a 97 2.3 that will crank but won't start when temps outside are around 80 or higher... Starter's fine, battery is fine, fuel pump is too. tried all morning and it would NOT start at all... Got home a fee mins ago and started up just fine... Anyone have any clue what could be causing it?

 

I had that same issure.. turned out to be the fuel pump relay under the hood was not getting good contact. Engine cold it worked fine. New relay and cleaned terminals along with a check on tightness of contact blades.

 

That's a good answer, i've seen someone have a fuse/box issue before like that, pushing the top of the fuse helped, so they got a replacement and all fixed.
