was the battery fully charged before installing it ? if it ran good before you installed the battery then it has to be your new battery at fault ?? unless i missed something here .. did you clean all posts inside the battery cables ? holler if you need more

Anytime the alarm sounds when opening the door with the key, get into the truck anyway, place the key into the ignition key switch and turn it on and off 2 times. The horn will stop blowing and the lights will stop flashing. You're ready to go.......

I am having the same problem. Where is the hood latch switch located? And what does it look like? Thanks!

try rolling down the window while in the car and put your hand out the door and unlock and lock the car while in it then start it.
