The primary resistance is= 0.5 to 0.7 ohms.
The secondary resistance is = 20 to 30 K ohms. Tom L.
0.010-0.014" is the Briggs spec
To test the ignition coil and ignitor on a 1990 Toyota V6, start by disconnecting the ignition coil's electrical connector and using a multimeter to check the primary and secondary resistance of the coil according to the specifications in the service manual. For the ignitor, you can perform a continuity test to ensure it is functioning properly; check for resistance between specified terminals. If either component is out of spec, it may need to be replaced. Additionally, you can check for output spark by connecting a spark tester to the coil's output and cranking the engine.

If you haven't already,Try replacing the plug wires and spark plugs and regap the plugs to factory spec.

If it repeatedly fails you have excessive heat, wrong spec condenser, its getting wet, the voltage is incorrect off the ignition (or magneto if you have one that primitive) or you may have a bad plug wire or coil causing the spark to "back up" into the condenser. ( How it was described to me in the 1960s ) It could also just be wired on the wrong side of the coil or points. Good Luck
Measure the resistance with a digital multimeter. If the resistance isn't within spec, it's bad.
timming just needs to be close the computer adjusts it to what it needs and the points are gone since the early 70's it is electronic with moduales, sensors and such
To check the ignition module on a 1975 Caprice with a 350 4-barrel engine, first ensure the ignition system is off and disconnect the battery. Remove the ignition module from the distributor and inspect it for any visible damage or corrosion. Use a multimeter to test for proper resistance according to the specifications in your vehicle's service manual. If the module shows no continuity or is out of spec, it may need to be replaced.

Timing is handled by the computer, there is no adjustment needed.
