Truck was fine and stranded us outside of Costco.
Will not start. Several faults and warnings. Flashing lights.
Brake fault. Transmission fault. HDC fault. Low coolant. Brake lights red and amber on and flashing.
Beforehand here and there get the "gas cap loose or missing" but disappears on its own.

It's not the battery. Checked by AAA, tried to jump at another time.
Not the brake switch, replaced.
Not the tail lights, replaced.

So there is power enough for radio and all warnings but very faint click for s fee seconds when trying to start.

Any help please? I need to at least get it started. It's sitting at someone else's place.

 

Have you had your alternator checked? Those are sometimes symptoms of an alternator that is not keeping the charge on your battery. I just changed mine in one of my vehicles that was doing the same thing. I bought the part and changed it myself so that saved me some $$. I didn't take mine to get checked but only because I knew for a fact mine went out. It's worth taking it to a local dealer or auto parts store and getting a free alternator test done. Autozone will test it for free along with several other auto parts places. Check levels in your battery and trickle charge it back to it's full amperage while the alternator is being changed to unsure the battery has a full charge once the new alternator is in, if that turns out to be the problem. Good Luck

 

turned out to be the transmission fuse.
