When I turn the key to on, I hear the electronics, (CD player maybe) but do not notice an relay noise. My dash is not working except for the odometer for only a few seconds. When I turn the key to start nothing happens. There is a Grey wire by the fuse box that I hear can be the issue, it seems tight and disconnecting/reconnecting did not make a difference.

 

Sounds like a dead battery.

 

Battery seems fine, the windows roll up down, radio works lights work.

 

The battery can have power to operate the electronics but not enough to start the vehicle. Get the battery tested.

 

OK I see, the battery is about 5 months old, if I jump it with another car or my jump box would that be sufficient if I don't have a battery tester?

 

Yes, if you jump it and it starts, the battery is suspect. Not the first time a new batter went bad. If you can get it to an autoparts store, they can test it. Or if you have a volt meter, stick it on there and see what the voltage is. That won't tell you everything, but if it is less than 12 volts, it won't start the truck.

 

I understand, it's just weird the dash gauges are not working, oil pressure fuel gage for example but the windows and everything else works.

 

Could also be a bad connection at the battery. Check all your connections under the hood.

 

OK thank you, I will check this after work and see if that helps.
