Van won't crank or turn over. Said to be blown fuse in the circuit.

Not cranking can be caused by many things such as Data Line, Ground, Pass-Key III Module, Power Powertrain Control Module (PCM), Theft Module, Wiring, Body Control Module (BCM), Connection or Ignition Switch to name a few. If a fuse is blow that is because of a over current problem, fuses do not just wear out, if you have a blown fuse you need to diagnose what cause the excessive current draw that blew the fuse and fix that before replacing the fuse or it will likely blow again (if it does not blow immediately as soon as powered up). If you still have this problem and would like it diagnosed and repaired please call Roy 456-0722 and make sure to let him know if you want a $10 rental car while yours is being repaired.
