Wont start without jump and has new battery

SOURCE: Check gauge light came on in my 1999 dodge

Charge your battery to full charge, next if you have a test light hook up the negative cable to the battery then with the test light touch one end to the positive battery cable and one to the positive post, is the light on? if yes is it bright? if yes Check your glove box and remove the glove box light check the light again, is it still bright? then check the rear cargo lamp and see if it's on if not, remove the bulb anyway and check the light one more time. if the light is still bright disconnect the light from the positive cable and the battery and then disconnect the positive wire to the alternator once it is disconnected do the light test again. Hook light to post and to the positive cable, is the light still bright? if no It's the alternator diode trio regulator Bridge, if it's still bright hook up the alternator wire again and then with the hood up and the hood light disconnected or the bulb pulled, locate the fuse panel and remove one fuse at a time, while you watch the light be sure to have the bulb out of the dome light so it does not give you a false reading. Now pull one fuse at a time if the light goes out thats where you have a problem on that circuit, on the fuse panel lid it will have it marked as what it is you can let me know what circuit it is and I can tell you how to check that circuit or if you prefer you can go to http://www.alldatadiy.com and buy a subscription for your car and it will have all the test and wiring information you want.
If you find the alternator is the culprit it could even be the brushes have fallen out one side or the other and is shorting if the battery is fully charged take it to auto zone and they can test the alternator output, if it does not put out 13.5 to 14.5 volts and 60 or 90 amps and 900 RPMS you know the alternator is bad just buy a replacement because rebuilding your alternator would cost as much buying a new or rebuilt alternator that has had everything done to it.
Now for the check engine light while your at auto zone you can have them pull the codes for your computer and that will help give you an ideal if the two problems are related. If the battery voltage drops below 10.5 volts the check engine light will come on because the computer is detecting low voltage if you run it on low voltage for very long you may burn out the computer. Hope this helps and thanks for using fix-ya

SOURCE: 2000 Dodge Ram 1500 (V8 5.2L) will not start

could be the battery, sometimes all the electrical would stay on but the battery doesnt have enough juice to crank the car over, if not check the alternater.

SOURCE: wife went to store and she calls me telling me

probably the starter is going bad. it hits a worn spot on the inside so it can't engage to turn over but most of the time it is not at the warn spot so it engages fine. make sure the ground is tight and not corroded and the battery post and clamps are not dirty, sometimes a bad ground connection or corroded batt. posts can cause intermittent failure. if it fails again, try the old fashion test by crawling under and tapping the starter itself with a hammer or similarobject. it usually will start and if it does, the starter is going bad.

o2 censers tell the ecm if u are burning lean or rich,,so it can correct it by telling the injectors to add more or less fuel,,,
