A catastrophic failure like this is going to be battery related. Check your battery cable connections at both ends. Make sure they're clean and tight. Also look in the underhood fuse box for a large, MAXI style fuse stamped with the number 100 on it. That'll be the main fuse. If it's blown that'll kill everything. Replace it. If the new fuse blows you have a major short in the electrical system. Possibly a worn positive (+) battery cable that's touching the exhaust manifold. HTH. - Jim
