What size/brand battery did you get? If OEM double check the obvious connections at the battery itself, and the less obvious connections like the one at the positive jump point under the hood. That connection is actually where battery power connects to the alternator and starter.

If you got a AAA then you screwed up, you need a AA.

Where are you jumping the battery from? Directly across the terminals or from the connection under the hood?

When you say it wont start, what happens? Does it turn over at all, or just slowly?

If I jump start right at the battery it will not start I have to jump it up front.

thanks

Bad connection between battery and front of car... check your wires and connections!

Like Cole says, seems you have bad connection on either positive or negative connections after the battery (probably in the trunk area as connections under the hood seem ok as you can jump start from there). The bad connection is probably ok to power accessories but cannot conduct the current needed to crank the engine. Check all main +/- connections on leads from battery to their terminals.

It's possible your old battery was ok

Found the problem, this truck was hit in the front when I bought it and it has a safety on the terminal that when you get in a accident it separate the positive terminal so you can't start the vehicle.

Ah, that makes sense... but you didn't tell us you had an airbag light!
