Hi folks,Got a bit of a puzzle,my 91 3XW has developed a strange fault,suddenly for no reason when I pressed the starter button the oil light came on but the engine didn't turn over,It's like trying to start it in gear,I've changed the starter motor and the solinoid,no change,If I take a screwdriver and short out the solinoid it starts first time,but it wont go into gear, Any ideas? and is it terminal !
