Just bought a brand new 2010 civic coupe LX. No add-ons, no nothing, and every once and awhile, it wont start. I only have 400 miles on it and I feel it's a lemon. Had it towed to the dealer last week and of course when it got there it started right up! They checked all electronics, my other keys, anything hanging from keychain, etc. They said bring it back and leave it a few days. that night, leaving a friends house, it wouldn't start again!, then after about 10 tries, it started. This is getting frustrating. Dealer swears it's electronic, but I'm afraid it's mechanical. If electronic it would be more consistent. can anyone shed light on this? I love my civic, but only when it starts!

does the green key light blink in the dash when it doesnt start? could be bad immobilizer unit.

If your Civic is an automatic, make sure it's going into park completely. Next time it doesn't start, press on the brake, shift into neutral and then try to start it again. If it works, it might be a picky park sensor. One of my cars does this occasionally.

Immobilizer in the security system is causing pressure loss to the fuel pump.
