HouseCallAuto 6/12/2013I want you to confirm a few things for me to continue. First don't just say that you checked the battery alternator and starter, tell me how you checked. Example, if you said I hooked up jumper cables to the battery and there was no change, I still have no power; then I understand the battery is good. Plugging in a code reader to the diagnostic connector will not make a dead electrical system come alive.
I am suspecting that you might have a burnt out ignition switch but I need more to go on. If you can confirm that a jump start does not help I want you to turn the key to the run position and then check for battery voltage at the underhood fuse panel at fuse 19 (this is an 80 amp main fuse - does not look like a regular fuse) also check for battery voltage on fuse 20 (a 40 amp fuse) and tell me if there is battery voltage there (12 volts or more).. Now after that get access to the under the dash fuse panel and find fuse 13 (a 7.5 amp fuse) and tell me if this fuse gets 12 volts when the key is turned to "crank" as though you were going to start the engine. If you have no power there then it is likely that you have a bad ignition switch or the battery supply to the ignition switch is open.
