SOURCE: I replaced my battery this

Check for power at the small wire at the starter with the key inthe crank position. If there is power than the starter is bad or the connections at the battery are not good. If there is no power put the trans in neutral and check for power again. If there is still no power let me know and I will get you some more info on trouble shooting the ignition switch and the PRNDL switch.

SOURCE: New battery car wont start

may just be a loose terminal. I had mine replaced and it took a few hours before it ran right again. something about the electronic modules take a little time to recharge.

Well, if you jumped the battery and it started, maybe you need a new battery. Get that checked out first. Also, when was the air filter replaced? I would probably take to an indy shop if it wasn't the battery or air filter because it could be a bunch of things: starter, fuel pump, fuel filter or fuel injectors.

2002 Gmc Yukon xl. Drove it one morning and returned home than ten mins. later went to start it and nothing. Dead. Turn key to on and all dash lights go our and nothing. Doesnt crank or anything. ...


Take the battery out of it and go to a auto store to get it checked, they do that free, but you might need to get it charged or get a new battery. If it clicks then it's definitely the battery, otherwise it could be something completely different.

Things to consider
-oil change?
-last tuned up?
-battery age?
-Alternator?
-check fuses?
-are you aggressive while driving it, that can cause internal engine problems over the years.

hope it helps.

Battery keep going dead, has new battery


Have you checked to see if the alternator is charging ? Run a volt meter on the battery with the engine running, have to have more than 14 volts. If 13 or less, then replace the alt.

I RECENTLY had my engine replaced in my 2001 hyundai Elantra. This 'new' engine supposedly has only 10k miles on it. A new alternator had to be installed.The work was done by the dealer. I have had the...


The odds are the alternator is the problem again. I've installed brand new alternators in the shop that turned out bad. The battery barely had enough juice the crank the car and get it running. Then, the battery was the only thing keeping the engine running with the spark plug until the battery drain completely dead.

If the alternator was working normally, the alternator would have kept the energy up and keep the spark plugs going without the battery's help.

Basically, the battery's job is to start the engine only and the alternator's job is to keep the battery charged and supply energy for the car's needs.

2003 Honda Accord. Dies when I try to put it in drive


you are having a problem with your alternator. the battery has a main purpose to start the vehicle, keep computer memory, and give power to electrical components when the key is in the on position. the alternator charges the battery and gives power to electrical components when the vehicle is running. now when you hit the brakes there was an extra load added to the alternator and if the car died then the alternator is running very weak and needs to be relace.

It sounds like the alternator belt or the alternator is going bad. The squealing sound was probably the alternator belt. the alternator belt might need to get tightened or replaced or you may need a new alternator. The alternator keeps the battery charged. When the alternator goes bad the battery can not be recharged. You also should keep the power steering fluid up to par or the power steering will go bad on you.
