I'm having ignition problems with my 98. The key free spins in the cylinder with no resistance, I can change gears without touching the brake, the truck stays in the "on" position. I tried the old screwdriver trick but the motor just kept turning over and didnt start, but the theft light flashed rapidly. Its not the ignition cylinder because i've replaced it and it works in my other truck. Any help would be greatly appreciated, thanks.
