Question about 2002 Jeep Grand Cherokee
No gauges, no lights no nothing. battery has a full charge
First check to make sure you have a good ground. Then if so go to your power distribution box and you need to check the main fuse. It will be the spade type and should be a 50 amp fuse. The other possibility may be a relay switch after the 50 amp fuse there are several. On the underside of the cover to the distribution box it will tell you which relay runs what components. This is just a starting point. Remember when you check electrical check the simple items first. More often than not people try to read more into it than is necessary. Think basic and simple and you will find the problem. This is a starting point. Without actually looking at your vehicle it is very hard to tell you exactly where the problem is located.

I would start by checking all the fuses under the hood.
There is a fuse called IOD which the factory leaves out and gets put in at the dealer.
That fuse could be bad.

It is likely one of your battery cables loose. Same thing just happened to me today. What you need to do is first lock the doors, and close them. Then you need to disconnect, and reconnect the battery cable, then if the security lights still blink you must use your key to unlock the door, then it should stop blinking, and start just fine.

There could be two problems here:
1. That buoy floating tank is not working properly
2. That the electrical system that fails to submit the dashboard.
Review this information:
Page 2 - Fuel Gauges description
Page 4 - Voltimeter/Tachometer/Fuel Gauge/Low Fuel Inoperative
Page 10 - Specifications
About Fuel Tank components
Fuel Tank and Gauge & Sensor Units Sending (Page 93 and next)
Good luck... and remember rated this help.

It takes very little voltage and amperage to operate dash gauges. You cannot rely on "seems" when it comes to the battery. A good battery should have standing voltage of at least 12v and be able to "snap back" from a fifteen second 200 amp load. Under load, the voltage should not drop lower than 9.5 volts. Have the battery charged and load tested before going anywhere else with this. then make sure connections are clean and tight. After you get it started, if battery was good, check starter draw and charging system operation. If it does not start, check power flow from key through neutral safety switch and starter relay to starter.
