The PCM in the later model Dodge cars and trucks are very picky about the battery voltage. If you needed to jump start the truck because of a low or dead battery battery, chances are you need to replace it.
I'd take the truck to AutoZone and have them check the battery. If the charge is too low, they won't be able to tet it till it is charged. They can (and are supposed to) pull the battery, if its easily acessible, and put it on the rapid charger then re-test. If it tests bad, then will gladly sell you a new battery and install it for you. And if it tests good, they'll re-install it and check the charging system with the engine running. And all that work is free, company policy. Can you tell I used to work for AutoZone?
As far as the battery being easily accessible, some cars like the Dodge Intrepid and Stratus, have the battery in the front fenderwell. Some yahoo at Damn Near Chrysler thought it was a good idea to put it there so you have to jack the car, and remove the wheel to get to the battery compartment.
Lastly, know what Dodge stands for? I can say this cause I bought my Dodge truck used from a Ford dealer while I was working as a contract employee at a GM plant.
