Default HELP!!!! truck periodically wont start

I have a 99 3.0 4x4 that periodically wont start. I just put in a new batt. thought that would take care of it... I was wrong. I've noticed that when it doesnt start the theft light flashes... I tried both of my keys and that doesnt help but when I jump it (even though the batt is all good) it starts right up leavin me to believe its somekind of crazy electrical problem... any suggestions on where 2 start would be awesome

they have chips in the keys, it might be a messed up key... when i first got my truck i got 2 spare keys made at the hardware store and alls it would do is flash theft... might have to take it to a dealer to fix that one...

make sure your grounds are good and that the positive/negative cables are connected good.

Sounds kinda like the battery is not all good then. Hook another battery up to it and see if the problem goes away its worth a shot before you go wasting money on stuff that you didn't need. Do you have the correct battery in it?

I know its a bitch but if you have an Advance nearby then take the starter off and have them test it. Sometimes if you have a bad spot in the starter it will crank up when you jump it off.
