Hi John D.,
The OEM ignition coils for Volvo 960, 90 -1998 are made in Spain. I'll bet by Bosch. A little bit of research to answer you question. Though I'm trying to find a Bosch PN, and I'll bet, as the form factor is unique, these Volvo 960- 90 series -1998 is a Volvo only part. These are Volvo PN 1275971.

The after market units I've seen are from Taiwan. FCP Euro lists these as made by STI in Taiwan. You may want to research a bit, using different search engines, as search engines can be biased. So a little Google, a little Bing, and little Duck Duck GO.

I've read you can test these ignition coils using a beefier than average multimeter with continuity and resistance function. I dunno the desired resistance range. People at the junkyards will collect these ignition coil over spark plug thingies. They are not so robust as a single oil-filled like that on 240. And grab extra parts like the ignition power stage, sensors, and the such.
960 ignition power stage by Bosch. You have two fo these in 960. iPd courttesy:

See: http://volvowiringdiagrams.com/?dir=volvo/960%20Wiring%20Diagrams
Specifically, the 1997 960 / 90 wiring diagrams. The diagrams indicate ignition stage location and which ignition coils they are connected to.

The green books. Dunno the model range.

Before you replace parts, check the wire harness continuity. Corrosion or a dirty connector, even at the power stage, could cause the problem.
Hope that helps you.
Duffed.
