it only happens every once and a while but i try to start it up and it just cranks over but never fires. i dont know if it is the humidity or what but what could be the problem. i heard it could be the main ignition relay but i wanna see what you all think!!!

 

main relay

 

is there any way to test it

 

main relay. you can resolder all the joints on the board. they crack and lose contact more often when its warmer temperatures

 

main relay

 

What years is ur CRX?? what model??? swap or no swap???

 

is there anyway to test it to make absolute sure it is the problem???

 

Yes, but i cant think of it offhand.

Look in the shop manual, it tells you how. Youll need a multimeter.

 

Yeah I have had 3 Hondas they all do it, turn the key, gets lights on the dash, but nothing. I usually disconnect my ground (battery) for 5 secs, then put it back on and the car starts right up.
