It took 2 tries to start my Accord today. First time it just turned over for a while so I tried again, second time it started after another extended crank but it sputtered to life. This was the second start of the day, first was moving the car about 200 feet. Maybe the super short trip was somehow the cause? Just odd since that car has less than 45K on it. I have experienced hard starts before in this car (maybe a total of 4 other times in the 1.5 ish year that I have owned it) but it would still start on the first try, just a little rough. Maybe I will throw in some Techron before the next oil change. The car is the Accord in my sig.
Accord hard start

Has the MAF sensor been cleaned lately? I just did this to the Matrix and it was very easy. Used some CRC MAF cleaner. Probably not a bad idea to clean the throttle body as well.

I cleaned the MAF sensor when I changed the engine air filter about a year ago. Throttle body has not been cleaned, I have never done this before but assume it can be done easily.

The throttle body is kind of pain now that it's drive by wire instead of cable controlled. I'd probably have the dealer do that one for $50 or so. I read where a dirty MAF can cause hard starts or where it starts then dies after a few seconds.
How about the battery? Clean, tight connections esp the positive terminal. Could be a weak battery.

don't bother, it was probably flooded from the very short interval you have run the engine the first time. Happens now and then. If it insists, check the spark plugs or something...

That could very well have something to do with it since all the condensation was quickly cycled through and didn't have a chance to burn off. A good hwy run should help. Esp if the car is short tripped a lot.
Hopefully some toptier fuel from a newer, high volume station is used.

Incomplete combustion.The plugs got loaded by the rich mixture,never got hot enough to burn it off and then got hit with another rich mix when started again.Just think of how cars in the carbureted era suffered under conditions like that.....fouled plugs.
Has it thrown a CEL?
I have a Dodge V6 with hard to start symptoms that turned out to be cam/crank position sensors. The computer had trouble reading the timing. Log shot but....

Maybe a bad tank of gas? Water or moisture. A bottle of Stabil 360 Performance with Vapor Technology from Walmart is worth a try.

My previous 2010 Accord would do the same thing once in a blue moon. I have had other 8th gen Accords do the same thing when being serviced at my body shop with multiple super short trips inside the shop.

Id check battery first. Are you on the OEM battery? Being in Florida Id guess battery first.

I've experienced this in new cars, too. I typically run the car long enough for the idle to settle, if I have to move it just a short distance.
Vapor lock due to starting it and immediately turning it off.
Moved it 200ft?
That scenario is one I avoid like the plague especially in the winter. Worst thing you can do to a car.

It only gets Shell, I am a believer in top tier fuels.

I try to avoid short trips when possible, but the car had to be moved so I moved it.
