1k ohms too high? Good find. It's one more out of spec part that you got out of the way.
Measure the coil wire and make sure the button in the distributor cap is good. Also the resistance of the rotor being too high will kill the spark. Volvo spark cable spec is 500 ohms per foot.
$5 on a test lamp and $5 on a noid light would go a long way.
That's not a wiring diagram.
