Check the battery,and connections,

Get a good strong high volt light tester go to the battery clamp the tester to negative side on batt. Pull the relay fuse last one on the left and insert the tip of light tester in the right side hole basically you need to pop the barker you will hear a click to check and make sure it popped test tiny fuses last row in the back of fuse box the alarm might sound if so take key insert in door and unlock turn twice so all doors unlock then put key in ignition and should start right up my husband figured that out when we got stranded inside storage unit gates batt died when we went to jump it it did nothing no lights no power sounds crazy but works!!!!!!! must try it!!!!!!!
