2002 accord ex coupe- v6.

Started it on Saturday after sitting for a week and everything was fine. Went out today (Tuesday) and it would only crank and not start up. I live in Md so it's been around 40 degrees and dropping below freezing at night.

-key is fine
-air filter is clean
- tried both pumping and holding gas pedal (didn't smell gas)
-don't think it's bad gas since it started the other day.

Any ideas? I've done some research and fuel relay switch keeps coming up. Is there any way I can test for this or rule it out? Any other suggestions?

If I got a code reader would it diagnose the issue?

 

Turn keyswitch to On and listen carefully for fuel pump to come on, run 2-3 secs, and cut-off. If you don't hear this sound, the Main Fuel Relay may be the problem.

Code reader will only help if Check Engine Light is staying on. If that is case, then get the codes w/ help from Autozone, or other auto parts store.

good luck
