I would do some more checking before buying a coil.
Coils rarely fail.

1987 Syncro, 2.1

Okay, what I get with this test is:

no spark
no sound from injectors (that I can hear-is it reasonably loud?)
fuel pump cycles on and off at consistent points in the engine revolution

suggestions?

My coil is not to the specs in Bentley:
2 ohms primary, Bentley says it should be (0.5-0.8)
3000 ohms secondary, which is in the Bentley range

I'd just run out and get a new coil, except that I already got a new coil,
and it matches the specs on my old coil. But it was "Wells" brand from
Autozone (yes I'm an idiot, no need to tell me). I figure that it's fairly
likely that I got the wrong coil or a bad one.

I guess that I need a coil, but am concerned that I didn't hear the
injectors firing when I did Ken's test. Is the coil somehow involved?
