All power to the car comes from the battery to the under hood fuse panel starting with the engine fuse (60 amp) can you check it and see if you have power to it and out of it and post back with the results and we can work from there.See the link for all the fuse that should have power in the link below, copy and paste the link to your browser to open and view it.https://dl.dropboxusercontent.com/u/104923897/Power%20dist%20Sept%2016.pdf
Where you able to take a 12 volt test light and or volt meter and check them to see if you have power to them?
You can get a 12 volt test light at most any auto part store for about $10.00 , you do not have to pull any fuses to check them, turn the key on and place the test probe on each side of the fuses on the small metal tab, the light should light on both sides if the fuse is okay.
In order to determine why you have no power we need to start with checking to see if the fuse panel is dead in order to have a starting point to trace the power distribution circuit. Also make sure the battery does have power.
The best way to test the fuse is to use a test light. They can often look okay but that not be the case.
So when you say there is not power to the car are you saying everything is dead in the car ?
Yes you need to test both sides of the fuses to make sure you have power on both, starting with the ones in the under hood panel.
Yes you should have the key in the on position to check all the fuse.
Do you have power in and out of the 60 AMP engine fuse in the under hood fuse panel, thats the one I wanted you to check yesterday.
The wiring diagram is showing it as a fuse. (60 amp) which is located in the under hood panel.See the fuse diagram again.https://dl.dropboxusercontent.com/u/104923897/Power%20dist%20Sept%2016.pdf
The engine B/b fuse (60 amp) is the one that you need to check for starters as well as all the other with the key on.
Okay I'm trying to help you find out where you have lost power and power starts to the complete system at the fuses.
Well unfortunately I'm afraid I have done all I can from here so I am going to relist the question for you in hopes someone else can give you some new things to check. Sometimes this type of problem requires hands on testing and can not be repaired on line. I'm going to open the question back up for you and if someone can help you, they will respond.
