When parked and key removed the dashboard lights and gauges will come on. They will stay on for several seconds and then turn off. They will do this for hours until the battery is dead.

Hi, I understand you have a problem with the alarm.
If the alarm is activated, and if the alarm is aftermarket you have a valet switch , That you can use to deactivate, or put in by pass. just you need to locate, is a little switch going from the alarm module to a dash or any strategic location.
When you found turn the key to run position them move or press the switch. and everything has to stop blinking.
If you are unable to find the switch, put the in on position,
Them go to front and remove the negative battery cable, wait 1 minute and reconnect, them try to start.
But if the alarm is a Factory alarm and you don't have the remote control. you can try deactivate with the key in the door lock cylinder. turning from lock to unlock position.
But remember this model of trucks, they use a chip on the key
If you don't have a key with chip it's gonna do theis problem.

I hop this solve your problem. Thank for using fixya.
