Try Replacing The Main Relay

 

Could be main relay, it seems like an electrical issue.

 

Im gonna change the main relay this weekend. I aprreciate the advice and will post if this is the problem.

 

x2 i dont think that would be a main relay, unless your having troubles starting when hot or the car dies when you come to a stop. sounds to me like a wiring issue also check all the grounds and recheck all your harness plugs.

 

Yup. When my main relay died it either wouldn't start or it would die when I came to a stop.

 

no go on the relay

still the issue persists know anybody who wants a 91 accord lol. Im stumped went back over thge grounds and harness's only other thing i can think of is that my light keep going dim and bright when i start the car.

 

did you check the throttle position sensor?

 

have you checked the catalytic converters? I mean its a 16 year old car it might be your cats.

 

No catalityic converter
