2010 Honda Odessey Handicap Van won't start after sitting for a couple of days. Have a new battery best from Sears. Mileage is @7K miles. and we don't use the van to often.

Not clear what is happening but you say it does not run a lot of miles. I do know even with a new battery the van must run every once in a while to keep the battery charged up. Batteries run down just sitting and has to run at least a number of miles to charge up. I suggest you purchase a little battery charger that you can leave hooked up to the battery all the time and when you want to use the van just pull the plug out of your extension cord. Then plug it back in when you are back home. That way you know the battery is charged fresh all the time. You might want to have the battery checked for power just to make sure the battery is operating properly. Any place that sells batteries should do this for free.

Sounds like your ECM / ECU may need to be re-flashed at the dealer, have you tried pulling the codes? The check engine light does NOT need to be on for it to have codes stored. The starting issue could be caused by the TPS / MAF / MAP sensors, the flashing of the odometer could be something with your PSOM chip or your VSS sensor. Pull the codes see what you get.

Recently we had to put a new fuse in the starter ???????????? What fuse ? location , size . A fuse blowing means a electrical short to ground .

ck. the ign switch and batt. terms.

No transaxles make 100,000 miles

What your saying, including the rebuild
is common

Asian transaxles & all Van type vehicles,
are something you don't want to own

I used to own a trans shop,so I will leave
you with that

Can't fix slipping,drive a couple of days,
& your pulling the trans out again

you should post a little more info . is it hard to start when it sits for a while meaning a couple of days ? or when its driven and hot then sits like when you are shopping then go to start it ? whats the mileage ? engine v6 or 4 cyl ? both of my camrys did this about 100,000 miles on each i changed the spark plugs and problem went away. hope this helps

Need to reenter the radio code, it's normally located in the glove box or behind the radio itself, once found you should have about 3 tries to enter the code, if more attempts are needed, disconnect the neg battery cable for 5 minutes and retry.

it is possible that you've got an issue with your power steering system, but the noise should be equally noticeable in both forward and reverse. the front differential is inside your transmission and if the differential is worn it will whine. if you pay close attention you may notice the noise when in first gear going from acceleration to deceleration at about 20mph. if this happens, it's most likely your transmission that needs to be replaced.

Hi

I have same problem - intermittently in my 2005 Honda Odyssey (Australian Version)! Same story with dealer response since of course it will not do it when I take it in (twice). Honda dealer says he cannot repair problem unless he sees it is broken! Very frustrating!!!!

I have had some success by putting the key in and out of lock several times and then moving it about when I try to start the car - normally this fixes it. I only hope this does not break permanently when I am far from home!

Keen to hear if others have this problem and have found a permanent solution.

Honda is notorius for bad MAIN RELAYS the solder in them crack and can not be seen with the nacked eye. This is due to simple expansion & contraction the solder heats up & cools down. Try that.
