There is information about testing most ignition components but I have not seen anything posted about testing the pick up coil. Intermittent starting problems began months ago after a 5 to 30 min stop in warm weather. Best start when problem occurred was to wait or use flooded engine start procedure. Check engine light would come on intermittently after start up and go out after next start up. Suspected faulty thermostat or temp sensor creating an improper temp signal and faulty fuel mixture.
Last time problem occurred engine would not start, towed it home and used your troubleshooting procedure for ignition system. All good so replaced ignitor, no help.
Only variance from test steps is the resistance of the ignition coil secondary circuit. At 50 degrees it reads 10,800 ohms. Probably close enough to spec or even correct at that ambient temp.
Check engine light goes out after 2-3 seconds and ECU smells good. I noticed there is no test for the ignition pick up coil. I assume there should be an AC voltage signal during starter engagement? What are the specs? Distributor shaft is turning.
One more thing that should not matter but will mention it. I piggy backed new ignitor in with a ground lead from metal mounting bracket to battery instead of installing it into distributor.
Any suggestions will be appreciated.
