3.2 gsi can be 2 things either the ECU is gone or the sensor is duff... i would replace the sensor first as that is the easiest and cheapest thing to do if that doesn't solve it trouble shoot the ECU, ( check connector, check engine loom, clean the lot, etc etc) if it is the ECU internals you'll probably will need a replacement ecu and a tech2 session. Make sure that the replacement ecu comes with the security code... otherwise it might be a very hard job to sort it out.

Change crank sensor for the first 3, the last 2 check abs unit and wiring could be faulty unit/broken wire in plug into abs on earlier ones common fault.
