I'm not really asking Q. but instead... sharing my experience with my Honda Accord 4cyl Coupe. I was looking for an answer everywhere about my Honda which wouldn't start yesterday morning. I found something but it has something to do with the relay. Well, I learned something today from AAA reps and just want to share this technique. It's probably have been posted here somewhere but it doesn't hurt repeating it since it's a good one

Problem: Car wouldn't start in slightly cool morning weather. I tried at night, then the morning after..., still the car would get a good crank but the engine wouldn't turn over.

Solution: I learned and it came from the AAA dispatcher/reps. The AAA rep took his hammer from his truck, got under my car, slightly bang under the gas tank while I was starting the car. Yup! my car started!!! My second guess was the fuel pump, but I don't really have time to do it and it was too late already, because I already made an appointment with my mechanic.
By the way, my car mileage as of today is about 96,000 miles so if I were you..., I will change my fuel pump before it reach that far as a preventive maintenance.

Good Luck
