Pick-Up Coil Resistance Check
Turn ignition switch "OFF". Disconnect connector from control module and attach ohmmeter leads (set in x100 scale) to terminals 7 and 31d of harness connector. See Fig 1. Measure pick-up coil resistance. If not to specifications, remove electrical connections at distributor and connect ohmmeter leads directly to pick-up coil terminals. If still not to specifications, replace pick-up coil assembly.
