To check the coil for opens and grounds on 3.1L V6 models, use an ohmmeter to check the coil grounds, primary resistance, and secondary resistance. To replace the coil, unplug the coil high tension wire and both electrical leads, remove both mounting nuts, and then install the coil in the reverse of the removal procedure. For 2.3L and 2.6L four-cylinder models, detach the primary electrical connector from the coil, check to make sure the coil is receiving battery voltage with the ignition key ON, and then use the ohmmeter's low scale to check the primary resistance and the high scale to check the secondary resistance. For Distributorless Ignition System (DIS) models, special testing equipment is required. For 1993 through 1995 3.2L V6 models, disconnect the negative battery cable, disconnect the spark plug wires, unplug the electrical connectors, and remove the three ignition coil mounting bolts. Installation is the reverse of removal. For 1996 and later 3.2L V6 models, disconnect the negative battery cable, disconnect the electrical connector and remove the coil pack retaining screws, pull straight up on the coil pack to remove it, and then install the coil in the reverse of the removal procedure. For 2.2L four-cylinder models, disconnect the negative battery cable, remove the spark plug cable cover bolts, unplug the spark plug wires, disconnect the electrical connector, and remove the three ignition coil/
Ignition Control Module retaining bolts. Installation is the reverse of removal.
