My 92 960 has a starting problem that comes and goes. If you turn the key fully on the engine wont turn over at all.You just here a click.Come back later it will fire right up.
The solution was i had to replace one of the relays on the shock strut tower i hope someone finds this help full. I had put in a new starter, ignition switch and pnp switch and problem still came and went. since the new relay no problems at all. The funny thing is i would get fault 223 in socket NO1 arrow flashing on dash swe flashing that has gone too since replacing the relay.Volvo Pn 89997635.
