I've got a 1998 2.0ES Accord coupe with 2 problems. Firstly, now and again after starting the engine it cuts out after a few seconds. When trying to restart it, the fuel pump doesn't prime. I've been told that it may be the fuel injection relay, but I can't seem to locate it.
Secondly, the car doesn't start after it's been standing over-night in the cold and rain. When it gets warm and sunny it starts after numerous attempts. Obviously after trying to start it I'm flooding the engine.
Any advice would be a great help.

This should point you in the right direction, even though your exact year is not shown:

Sounds like you have main relay failure, where ambiant temperature is affecting the circuit board's solder joints. I would buy a new one, rather than trying to resolder.

Did you mean you have a 1998 Honda Accord Coupe EX, with a 3.0L engine?

Hi, I just posted something about starting my Accord coupe and you might want to try it ;)
Get under your car, slightly tap/bang the gas tank while some else start the car. If it starts right away... that's your fuel pump. Because I tried all day yesterday, morning, afternoon, and night time, the car wouldn't start even I had good juice. Today, a guy from AAA bang under the gas tank and my car started right away!!
