This sounds like a short somewhere. In my city, we have a car shop that specializes in auto electrical. They can trouble shoot any electrical problem within a half hour in most cases.

They charge $30 per hour + parts. So in my city, you would most likely be charged $15 to tell you what the problem is, and then be given a quote on what they would charge you to fix it. Most places will charge you for the full hour even if it takes them 10 minutes though. So be ready to pay for hours at a time.

This is the quickest and most economical to determine what the problem is SPECIFICALLY. Eliminates guessing, tells you if it can continue without causing any further plobems if not corrected, and saves you time and trouble of uncertainty.

I would suggest you look into your local auto shops and ask around for any suggestions as to which shop is known for good and reliable service.

If you have roadside assistance on your cell phone, the tow won't cost you anything either.

I hope this helps. Good luck,

This sounds like a ignition switch (electrical) on a Honda Accord. Will start and die and if the lights are not on the dash car will not starts.
Start the truck and barely let the key come back so that the starter is disengaged but not all the way back to the run position.

You have one of two possible problems. 1. Battery connections are loose and/or corroded. Remove them, clean them, put them on tightly.
2. If that doesn't solve it, you have a battery that is weak, Once it's started of course the alternator takes over. Get your battery tested, replace if needed. If you have a volt meter, you can check it yourself. Battery should read at least 12 volts when you check it with the vehicle not running and everything shut off. When it is running it should read above 13 volts if the alternator is working.

If neither of those solves the problem, then and only then do you start looking for possibly a starter that is going out and drawing too much current, or a wiring problem.

Answer 4

Check your battery connections & also the alternator belt. If this doesn't work see the dealership.
