get your manual, find out were your fuse box is , and check your fuses one by one , have your keys out when your doing this, look for the main fuse first, and if any of the fuses are gone , you will see a broken wire through the see through body of the fuse, just replace it, also check the battery leads going to the battery poles on the battery, make sure there tight, do this first, and try start it, if no luck go check the fuses then.
