New battery but car wont start?

car wont crank or car wont start? I would say your battery cables are bad,, acid gets in from battery and erodes internal cable parts... need a Meter to check it out.. put the meter on battery while someone tries to start it, if the voltage drops from 13.5 to 10 then it is trying to turn over, I always have the new starters tester before I leave a store, they are remanufactured in Malaysa and they use old parts in most of them..

It is possible that your new battery has gone bad. The other option for having a dead battery is a draw on the battery by some system not going to sleep

have the battery load tested as brand new batteries can be faulty. Check that the terminals on the battery are shiny clean and tight. Check battery leads are in good condition and not corroded away and check the earth wire is fixed and in good condition.

Does the new battery turn the motor over? Sounds like bad/dirty cable connections...

I need a little more reason why you have a new battery?

Time for a new battery. Most places will test your battery for free. Expect to pay about $100.00 for a new battery for your truck.

battery is no go at all
1.if it starts off a jump.....
altinater could be bad...take positive battery terminal off battery while car is on ...if it stays running its good if car dies altinaters bad.

Very likely the new battery is defective - it happens. If you have a know good new battery, then also connect a jumper from the battery negative to the block just to be sure its not a defective or loose ground cable.
