Check your security guard system if it has it probably think! that you're the burglar and shutdown the system.

Read the battery voltage what is it? Double check all connections on the battery. Why did you replace the battery is it because of the present problem or what-talk to me.

I replaced the battery because it would not start or take a jump start, when I put in the new battery the truck started and died i started it again and it died, then i checked the fluid levels they were all good, so I started the truck again and gave it some gas to keep it running then i drove it for 1 mile parked it dissconnected the battery the nexted day reconnected the battery and no power to anything it's like there is no battery at all. The battery reads 12V.

12V ??? 12.6-12.8 volts will spin that rig of yours like nobody's business. below 12.4 its no good. A 12.4volts during cranking will drop way below 9.6 volts.

Okay Lets start checking fusible links in the power distribution box if not there, could be on the battery terminal on the starter.

Sorry 12.6 Volts I figured 12V was good enought. If I'm not getting any power to lights. radio, power windows or locks, or to the dashboard how can it be the battery terminal on the starter? I how many fusible linsk are there? Where is the power distribution box located? I found a inline fuse and it was ok.

thank you for the help so far. I will keep checking.

Check both wires comming from the battery. The ground, take off the bolt and clean end of cable then reattach. comming off the positive side of the battery should be two leads coming together before they connect to the battery. the heaver wire goes to the starter and the smaller one goes to the power distribution box by the dash under the hood. Check the corrision on the wire that goes to the box where they split by the battery . sometimes wires build up corrosion on the inside.

I treally sounds to me like you have a poor connection of your ground wire to the metal chassis. If this is loose, broken or corroded, you will have a condition where nothing works electrically. Follow the wire from the negative terminal on your battery to where it attaches to the frame of the vehicle. If this connection is loose or corroded, nothing will work.
