Does anybody had this problem on a 2000 Honda accord it drives good for about 15 miles then when you turn it off then restart it car the check engine light comes on then it run rough then I pul out th


Have you changed batteries lately? Sometimes a new battery can make the car's computer go haywire which affects the info sent to the fuel system. How new/old are your battery cables? Have you tried a mixture of baking soda and water poured on the terminals to eat away the acidic build up that affects electrical connection. Its possible that when you turn it off enough residue builds up with heat-arcing-interaction with alternator, etc. Get you computer's error code read to you from a shop that can link to it and see if it reveals the answer to your problem. Never underestimate a battery's ability to goof up your vehicle. :)

Since you can start with the pull starter, and not when you crank with electric starter, assuming this machine has electronic ignition it is quite possible that the battery lead in not making good contact with the battery and there is a big voltage drop low enough to affect the ignition system due to the high current drawn by the starter. Try cleaning and retightening both battery leads and the ground lead. Also check the power cable running to the ignition system. Also check for corrosion near the ground connection on the chasis.

The overdrive kicks out intermittently with no perceivable reason on my 1992 Dodge ram Diesel.


Believe it or not the most likely cause is a weak battery or batterys, and/or dirty battery cables. It causes electrical noise in electrical system which affects the computer. Test each battery indepentantly and clean all of the battery cables and grounds and see if that helps.

Electrical short or loose connection


did this problem start after the new alternator or is this the reason you replaced the alternator? sounds like a loose wire on the alternator or the battery post. make sure the battery terminals are clean from corrosion. if there is a hot spot on the wires or connectors that is a good sign that is a loose connection.
