Engine code a23 for 2010 Honda oddessy - 2010 Honda Odyssey

drain most of it out and refill with good fuel

do you have access to an OBD2 scanner?
you need to know what are the trouble codes that are stored in your vehicle's computer

you can get a FREE trouble code scan from your local autozone or advance auto part

then go from there...

There is a 5 digit code on a white sticker as you open your glove box. Use the radios preset buttons to enter the code. You will have 10 trys to enter the code correctly

That could be a fuse problem or wiring problem. i would first check the fuse since it is the cheaper route to go.

check the tires or you might need a wheel alignment

are you sure you have the timing marks correctly lined up? If so, try holding the gas peddle to the floor while cranking the engine. This has helped me in the past with hondas.

jack up van,take off tire,remove brake caliber, pads and the rack they set in,than remove rotors
