Does anything electrical work? For example, do the headlamps work or brake lights?
If nothing is working, I need you to check the battery to confirm it has voltage. Use a multimeter or voltmeter. If there is voltage, go to the fuse box and check to see if the fuses are getting power. You can use a test light for that.
Here is a link showing how to test the fuses for power:
Let me know. Also, confirm the ground wire from the battery is properly attached to the engine block and body. Checking fuses for power will test the positive.
Let me know as much as you can.
