If continuity is present, then check for resistance between ground and the ignition coil connector. If there is no continuity repair the open or short to ground in the circuit.
Disconnect the PCM connector and check the continuity of the driver between the PCM and the coil. If there is no voltage on the driver circuit, then turn the ignition off. If there is any significant voltage on that wire then there is a short to voltage somewhere. If you don’t detect any frequency signal from the PCM on the ignition coil driver circuit indicating the PCM is grounding/ungrounding the circuit (or there is no visible pattern on the scope if you have one) then leave the coil disconnected and check for DC voltage on the driver circuit at the ignition coil connector. If there is a Hertz signal, then replace the #2 ignition coil. Use a Voltmeter in AC Hertz scale and see if there’s a Hz reading of between 5 and 20 or so that indicates the driver is working. Using a scope will give you a visual pattern to observe, but since most people don’t have access to one there’s an easier way. Then start the engine and check for a driver signal to the #2 coil. Repair as necessary If the engine is misfiring presently, stop the engine and disconnect the #2 coil wiring connector.
Verify the harness isn’t misrouted or chafing on anything. Check for poor connection at the coil connector. If manipulating the wiring causes the misfire to surface, repair the wiring problem. Try wiggle testing the wiring at the #2 coil and along the wiring harness to the PCM. Solutions Is the engine misfiring presently? If not, the problem is likely intermittent.
