Hi I was wondering if anyone else has had this problem or knows how to repair it? I have a 1992 240 4cylinder with 170K miles.

Last summer i had a problem with it not wanting to start when it was hot outside. It didnt want to start in the heat of the day but would eventually start after many tries or later in the day after it had cooled off. Fall came and the problem stopped all through winter no problems but here it is 80 degrees again and Im having problems with it not wanting to start again.

Its like the fuel is evaporating out of the carb. or something? Or the heat is causing a diaphragm somewhere to swell? I dont know this is just my speculation. But I need to get this fixed asap.

Any advice or knowledge on this problem would be greatly appreciated!

 

I would start by getting the codes from the ECU, see the LH2.4 section here:
