Good day all,
No spark condition: coil ohms are 0.45 primary, 9,105 secondary
Can I check output of ignition amplifier with voltmeter? If so, what should I be looking for?

Did this issue just start or was there anything which shuld some kind of signs prior?

Being a 97LX and no serial number it should have EST distributor. Check the distributor

TY alldodge, neither lead is shorted to ground and coil itself measures 952 ohms - does this mean amplifier has failed?

Check the gray wire with coil disconnected from harness, and disconnect tachometer, then to determine gray wire is not grounded. Disconnect the shift interrupter

If you get power to the coil when key is turned ON, and connections to other wires are good, then I would say it most likely is the module
