I've also noticed hard starting in my 09. Seems to coincide with rain. Blue skies today, car started normally.

 

i have to on my '10 sport AT model not even a yr old with 26k on it only hear recently to

 

Not sure if its related cause mine never did this, but when i first got the car brand new, i quickly did the upgrade used for amplified audio systems called the Big 3 including 1/0 guage, platinum terminals and kinteiks battery with solid grounds to chasis/engine/battery/Alt and noticed the car started faster than it did the first week i had it prior.
Unsure if that would actually help the issues described here though. But was an improvement over factory for startups thats for sure. A fuel additive may also help.

 

Mine is starting to have a hard starting problem now too, its a 2010 sport

 

If the car is getting 38mpg (standard for me), and no lights are on, and I've performed the required maintenance, and it starts after a reasonable number of cranks, then I don't worry. I have two fits. The one with higher mileage takes a second longer to catch after cranking. I have to remember to stay on the key for that bit in the higher mileage car or I let go, as I would in the other car, without the start.

 

Temps are up in the high 80s now and I'm having no more lag starting. I think it's just cool weather with summer gas that started shipping (May 1st? Sometime in April for CA?).

Also I think the definition of "hard starting" is more than a couple extra seconds cranking the engine. You guys probably never experienced the joy of finicky chokes and accelerator pumps on carburetor equipped engines. Hard starting means you walk.

 

Problem started at 9000 miles. Extra long cranks, even after waiting for fuel pump to prime.

 

For 22yrs I've been trying to erase the memories of starting an F150 from my mind. I walked many a time and eventually walked away from that beast - really, left it where it sat.

 

My car has been starting very good the last week but today it almost backfired and had to crank it 3 times before it started. I noticed the barometric pressure went up and my fuel trims were -4.7 for both but when I got home the fuel times were -2.3. So it has something to due with both. The temps are cooler too. Nothing like winter in May. 30's wind chill. I also found this http://www.oxytane.com/mystery/fuel%...d/P2002_04.PDF . Hope it explains a cold start.

 

That sounds like a high tension wire issue.

 

Check battery. Honda has a run of poor batteries with short service life.

 

I have a 2010 with under 4000 on it and it does it every once in a while. I never really paid much attention to it. I have had other vehicles too that if you just try to touch the starter quick and release it, it won't start. You just need to make contact a little longer. My e150 conversion van does the same thing...it all sounds normal to me. No recalls on mine yet.

 

My '09 did this before the LMS recall was done. Haven't had an issue yet.

 

Unless the car cranks slower its the fuel trims and ethanol with the changing temps and barometric pressure. Ethanol doesn't burn easy until the engine gets up to 160 degrees and thats why it lowers the emissions at startup because it dilutes the exhaust gas with ethanol. Thats why it smells like ethanol when you first start the motor.

 

40k mile 09, and having the same problem. Oddly enough it started right after the LMS recall was done. It was also at the end of the winter, so I don't know if its temp/fuel mix related. It's definitely not a battery issue. It really sounds like the fuel system bleeds down back into the tank the pump has to re-prime the system. I work for Audi and we had issues with the 05-08 2.0T A4's where the fuel filter check valve would stick open and cause extended crank issues.

Weird so many people have this problem and no one at Honda has caught onto it.

 

Perhaps because it's not a problem? No one's car has failed to start; it just takes half a second longer.

Cool temperatures and summer gas is the perfect explanation.

I wonder if they shipped summer blend earlier this year for people to notice in numbers, or if it's mass hysteria (fits?)?

 

Mine is doing this too, but I've had prior cars to the same thing when the weather is constantly changing.

 

yep, the ECU is constantly adjusting to the working environment so this is normal. especially when the car was driven and shut down during cool dry weather and the car is re-started in warmer damp weather.

 

Haha this is it ^^ We all read this article then pay close attention to start times :P

But on a serious note, I've noticed it as well.

 

I'd be happy to attribute it to that except I noticed it before the thread- I realized that I was in the habit of cranking it for enough time for it to start, without really paying any attention. And a couple of times I let go of the key, and the car wasn't started yet...
