drove fine all weekend. then tuesday morning i got up to go to work. did the usual, eat got dressed and left, got out to the truck and go to start it and nothing, doesnt turn over. everything works, windows radio wipers, just when i turn the key everything cuts off. and it doesnt even try to turn over, i tried jumpin it thinkin who knows, also gave the starter a good couple wacks, truck didnt do anything unusual lately alls was good till i tried to start it. also i checked all the fuses. thinkin possibily a ignition switch?? just dont want to spend the 70 bucks if that aint the problem. thanks
