My next book worked fine since the day I got it, until today. It won't turn on and I've tried multiple times today. Any suggestions to get it back on? It's very useful to me and if like it to be working again

Check connection.

I suggest you get another unit as the water or moisture in the box will not be helping at all. In all your fault codes if it is the box you would have had a fault code that includes the cpu as a source of the fault.

CHECK BATTERY CONNECTIONS, STARTER CONNECTIONS, WHAT DO YOU DO WHEN IT DOESN'T START, TO GET IT GOING AGAIN, DO YOU GET A JUMP START IF SO CHECK CONNECTIONS.

It would seem that you have overfilled the freon level.

Sounds like your problem might be with the VATS anti theft system. Does your truck have the chip in the key? If so you might just need the ignition lock cylinder changed out. There are 2 very small wires that run from the lock cylinder down the column and plug in under the dash. After time the wires insulation will get brittle and crack. The wires read the resistance of the diode chip that is in the key and send the signal to the VATS computer witch tells the ECM weather to send the signal to the fuel pump or not. On a cold moist morning the resistance signal can be interrupted or the resistance lever raised enough for the computer to get an improper signal. Your vehicle is thinking that an improper key is being used to try and start the vehicle. A replacement lock cylinder can be purchased for around $80 at your local part store and you will need to take your current key and the new cylinder to a lock smith to have the pins in the new cylinder changed to fit your current key. This way all of your current keys will still work the vehicle instead of having to pay $40 for each new key. Anyway, after you have the new cylinder working with you old key simply take it in to have it changed out, shouldn't take any competent mechanic with the right tools more than an hour to change out.

Thats what i would try and if that dont help, maybe check the connections at the starter.

The gas u put I'm the tank was high octain if it was it was making the engine fire to early replace the gas and it should wor properly

Have you verified that system has been "burped" of air? That the fans kick on? Check radiator hoses for kinks. You can try running without the thermostat to see if that helps and can identify if the thermostat could be a problem. You may need to check your coolant mixture too.
Sounds like you have reduced flow or restriction in cooling (heat exchanger) as it runs fine at cooler temp but can't keep up when it gets warm.
New parts don't always equal working fine parts.

Sounds like its a starter problem,if you can pull the starter off take it to an auto parts store,

there are many locations that have equipment to put a load on the starter, and they will be

able to tell if its bad. once you pull the starter off, if you can check the teeth on the fly wheel,

if there is a dead spot, the starter could spin and not engage the flywheel. I hope it's the

starter. the bendix on the starter the teeth that engage the flywheel could also have dead

spot's. and not engage all the time. good luck!

chek the alternator
