I have a 92 accord ex. When the car is hot or its jut hot outside, the D4 light flashes and it WONT start. It turns over but wont start. When its cool outside it will start. Does anyone know what is or could be the problem?

 

you need a new main relay. u can either buy a new 1. or taje yours out and re-solder the connections.

 

i took mine out i put it in the refrigirator and i put it back in and it worked for about a month

LOL LMAO,,,LOL, Next time put it in the freezer it might last longer ( 2-3 months )???

 

it does indeed sounds like the typical main relay issue..Remove it, take it apart and look at the solderings most likely some are cracked ,,you can resolder them or buy a new relay ..

 

obviously your not familiar with the problem the HEAT and HUMIDITY affect it the most

 

All about main relay's in this web http://techauto.tripod.com/mainrelaydefine.htm, They explain how to test and fix or replace u main relay, regards

Two idiots in one thread. I'm sure it's not a record.
I'm well aware of relay issues. I have a 92 EX. Cracked solder joints are not repaired in the refrigerator. Removing and replacing the relay, however, could shift things a bit and allow better contact for a while. Humidity has NOTHING to do with it.
