I have 2004 Honda civic EX and haven't driven the car for about 6 months. It's been sitting in my garage, so of course the battery was dead(it was 6 years old anyways). Replaced the battery and when I went to start it, the car cranks for a long time and doesn't start. I have power in the car and everything seems ok.

So, I checked for a spark from the spark plugs and yes there was spark. I pulled the ECU fuse under the hood to reset the ECU and still have the same problem starting. I checked all the fuses and they're all good. Could it be the immobilizer? Green key light flashes only when I pull key out of ignition. or something with the ECU?

I don't get it. I've never had a problem with the car before until now after it's been sitting for so long. Any thoughts guys?

You probably have plugged injectors due to sitting... Get them cleaned or replace them. It should solve your problem.

I use chevron with techron all the time when I was driving it. Techron should keep fuel injectors clean right?

Thanks for the help.

Chevron and Techron are crap. Go get your injectors cleaned hopefully it fires right up after that. One member on here bought a new engine that had been sitting for a little while and the injectors were causing a no start situation. Hopefully the same goes for you cuz it's an easy fix.

I'll go do that. This thing is driving me nuts because everything else is fine. Now I got to get the car towed to the shop. Hopefully that's the problem.

Thanks for the help!

yeah theres no way its a battery issue unless you hooked up the cables wrong or blew the main fuse. you changed out all the old gas right? i wouldnt use untreated gas that was over a month old. if it has fp-plus in there, it should be good for a year.

Nope didn't change out all the old gas. Don't know how I would go about doing that. We'll see when I replace the injectors.
