i've read through past posts and still trying to figure out on why my car will not start, even after installing a new Odyssey PC680 battery.
originally, i let my car sit for 2 weeks as i did the usual maintenance of changing the oil and flushing the radiator. i tried starting the car and the battery was completely dead, as i noticed the mileage indicator was at 0. i charged up the battery and the car cranks, but still has trouble on turning over. the power windows, stereo, etc... all works, but the car just doesn't seem to crank over. i purchased another PC680 and still the car wouldn't crank over. i noticed that the battery level was low as i hooked up to a battery charger.
does anyone have any suggestions? i have a greddy fmic, which gives me space limitation. i plan to take the battery to autozone to get it checked out, yet i'm also looking at the buddy club mini battery. or the last alternative is to relocate my battery, which i'm uncertain if the car will turn over.... any suggestions are welcome.

 

Have you checked to ensure you have fuel and spark.? If the car is cranking it is probably not the battery. I am also using the Odyssey PC680 battery with no issues.

 

how big is your battery charger???? If its the small type your by at the parts store for $35, it will not have enough amps to start your car with a dead PC680. You need a big Jump box.

 

i smell the fuel from the exhaust and see the smoke from the tailpipe. the engine is cranking but won't turn over. the power windows, stereo, and even the stock alarm works... the plugs are new ngk 10.5 with 1500 miles. along with the nology spark plugs. just can't seem to identify the problem. i'm planning to take the battery to have it checked at autozone and also try to jump the with the original larger battery. but then again, if that doesn't work... i'm not sure what i should do next.

 

Do you have a volt meter, or a PFC? So you can watch the volts while you start the car. I have had a similar problem. Were with the car sitting there, the battery would read 12-13 volts, then when I would try and start it the volts would drop down to 6-7 volts.

 

just figured out the problem... my ngk 10.5 racing plugs needed to be cleaned. battery is fine, just needs to be started up after a few days of sitting around.
