AE92 Toyota Corolla - No spark - Faulty Coil Diagnosis and replace
So after diagnosing that I had no spark in the AE92 corolla yesterday I dug a little deeper into the distributor to see if I could pin point the problem. To my surprise the car did start and run just fine today which means I have an intermittent fault which is always harder to fault find and test. However with further testing, 1st using the on board diagnostics (OBD) port without a tester, checking the timing signals is going to the ecu by testing the injector pulse with a multimetre and finally check the coil resistance. I determined the coil pack is failing and remove the coil pack for replacement.
