Pull and clean all of your battery connections.

Also take out and put back in every fuse in the in the fuse panel. They get corrosion on them and do just what you experienced. You do not have to replace them with new ones, just remove and put back to clean up the connection.

Try to tighten the fuse block thru bolt

There is a bolt that holds the two halves of the fuse block together....like a clam shell... if you will. I believe the bolt is on the engine side of the block but it has been a long time since I had trouble with mine and I have slept since then. It is right in the middle and pulls the inside and the outside together and when it does it connects the two parts. I found power on the wires going into the fire wall on the inside but none on the other side of the firewall under the dash on mine and tightening the bolt fixed it. Good luck.

While you are at it, disconnect the batteries and then disconnect this harness from the engine side of the firewall. Clean the heck out of the connectors with electrical contact cleaner and a toothbrush. Then reassemble with a healthy does of dielectric grease!

If your lucky.. Open the hood and look for sparks. That's how my last no power diagnosing went.
