1989 TPI, All stock. No spark. Changed the ignition module, cap & rotor. Still no spark. What else would cause no spark?
How do I test the coil ??

 

Resistance testing the primary and secondary windings would be a good beginning. If injectors are not pulsing that would indicate no signal from the pickup coil, and that would also keep the ESC from firing the ignition.

 

Also make sure you're getting 12V to the coil while cranking.

 

Have you checked your spark plugs and wires?

 

It's upstream of the wires & plugs. It's a no spark issue from the distributor or coil.

 

No gas in the oil, no gas out the exhaust. But 45PSI at the rail. So I'm assuming injectors are not pulsing, or I would smell fuel somewhere.
Are you telling me I'm pulling the distributor?

80,000 miles, but there are constantly rust particles under the cap & rotor area. For years I have no idea where these particles are coming from.

 

This problem was caused by a bad pickup coil. Rusted .. corroded along with the stator being worn out.
