My 2001 Honda Civic will not restart after stalling. It restarts fine with battery jump start. Is this an easy fix?

Remove and fully charge, or replace, the battery. Most auto parts stores will do this for free.

I had a new battery put in less than a year ago. Is there something else that could be causing the problem. If I stall the car or if I do not fully engage the clutch when turning the car off, it will not restart without having the battery jumped. However, if I turn off the car with the clutch in all the way, it turns back on just fine. The only problem happens when I accidentally stall.

Anytime you have an electrical problem, you want to establish a baseline of known good items. This involves removing and fully charging the battery. You need to rule it out as a possible cause. Since it always restarts, when it is jumped, the battery is suspect. Afterwards, I would also have an auto parts store test the alternator for free. It may be bad and allowing the battery to discharge too much. The alternator's brushes may have worn down too far or there may be a problem with the voltage regulator. Regardless, these items need to be tested, since you are having to jump the battery.

Let me add that I never recommend jumping modern days vehicles. There's too much risk that a voltage spike or connecting the jumper cables wrong will destroy the ECM, alternator, or sensors. We've had more than our share of these situations at AMHD. These are nasty problems that are expensive to fix.

I'm not sure what the relationship is between the Neutral Safety Switch and why you have to depress the clutch pedal, before turning the ignition off. See if this "goes away," after the battery is charged. I would also clean the battery terminals and cable connections. Afterwards, ensure the connections are tight.

Thank you, I appreciate your thorough response!

Make sure they actually place the battery on a charger. Have them check the fluid level of each cell. Then, let it charge until the ammeter cuts back to between 1 and 2 amps.
