Volvo 1999 S70 Intermittent Start

Increasingly, my s70 won’t start. Turn key and nothing When this first occurred this spring I had it towed to my mechanic. He found that a starter cable was starting to detach. He re attached and started all summer with a few exceptions. Now this fall it is not starting every couple of days. Turn key and nothing. Have if towed to the mechanic and it starts fine. So should I have the starter replaced? Any guesses on what else it could be? Thanks.

Volvo s70 question

Did he replace the cable or repair it? If he repaired it, I would start by replacing both cables ( ground and positive battery cables ). Also have the starter and battery tested at that time.

Thanks. He re attached the cable end to the cable. He did not replace the cable.

I suggest you clean the battery connections using a battery post cleaning brush. If that doesn’t help then there may be a problem with the safety switch. See if it will start in neutral. If that works then the safety switch needs to be checked and possibly replaced.
