My 2000 Honda Odyssey EX has intermittent start problems. At least once a week it will not start without being jumped with a portable jumping system; sometimes turning the key to ignition for about 30 seconds works. Battery is brand new; I had the Honda dealer run a complete starting system diagnostic (twice now!) and test, and they can't find anything wrong. Alternator and Starter tested fine. What could be wrong?

Thank you for using FixYa, have a nice day

doble check the alternator... take it to a different shop or mechanic, check the battery, maybe the battery is dead or it does not storing energy... if it not solve the problem, check for grounded wires, cables....

for the mess up with the everthing not working disconect battery for 5 min..

You need to remove the battery cables and clean the connections with a wire battery terminal cleaning tool. Then start the car and check the voltage at the battery with a multimeter. It should be between 13.5-16 volts. Any less and the alternator is defective. If this all checks out and you are 100% sure nothing is on drawing power then the battery more than likely has a dead cell. Remove the battery and take it to your parts store and have it tested. You will probably need a new battery.

sound like you have problem in the gear position switch.it will cause no start problems if its faulty.

no. removing the battery or disconnecting it will only reset any "service engine" lights or other warning lights that may be on.

go to the dealer with your registration , ownership papers and, vin# the dealer will reset it

renew sound system jump starting it without turning it off has cooked a chip in the thing somewhere its called brownout ,not enough voltage can cause more damage than too much

bad battery is what u have

P0740 Torque Converter Clutch Circuit Malfunction
The problem could be the torque converter itself or the sensor circuit for the clutch.
Best to have a Transmission Expert look at it to see if any further damage has occurred.
