1998 xj had no spark. Coil circuit code came up .changed coil .still no spark. Wiggled wiring harness aggressively . Fired right up. Wires in harness that ran alongside engine block on passenger side were slightly melted together . Re-routed them away from block . It starts for now. Wish I was more optimistic. Can you get a new quality harness ?
