Before replacing ignition components, check for Federally mandated extended warranty eligibility. Be aware that disconnecting the battery may affect the Powertrain Control Module (PCM).To replace the Duraspark ignition coil, disconnect the negative battery cable, mark coil wires, remove high-tension lead and coil connections, and remove coil bracket bolts. Install a new coil with silicone grease inside the high-tension lead boot.To replace the Duraspark ignition module, disconnect the negative battery cable, unplug module connectors, remove mounting screws, and install the new module.For the Duraspark stator assembly, remove negative battery cable, distributor components, armature, E-clip, ground strap screw, wire retaining clip, and stator assembly. Clean and reinstall the lower plate assembly, stator assembly, armature, and other components.For V6 engines, similar steps apply, but include additional steps to remove the lower plate assembly and stator assembly.For the TFI-IV ignition coil, locate coil assembly, unplug the connector and wire, remove screws, detach coil, and install new coil with silicone dielectric grease in the coil-to-distributor lead boot.To replace the TFI-IV ignition control module, follow the specified steps for removal and installation. Apply silicone dielectric grease to the module's back.For TFI-IV or DI distributor stator replacement, remove distributor cap and wires, follow steps for stator assembly removal and installation. Check for wear and replace faulty parts.

The negative battery cable must be disconnected. One has to detach the wiring harness connector(s) from the ICM. The ICM should be removed by taking out the mounting bolts. To reinstall, put the ICM into position and mount it using the bolts. Tighten the bolts to 22-31 inch lbs. Attach the wiring harness connector(s) to the ICM. Connect negative battery cable.

Position the ICM onto the right-hand, front fender apron or intake manifold. Tighten the mounting bolts to 90-120 inch lbs. (10-14 Nm).

On DuraSpark systems, you should examine power to the module, resistance of the distributor stator, and ground circuit continuity.

Remove the two screws holding the module to the heatsink.

To replace the TFI-IV or DI distributor stator (PIP sensor), remove the distributor cap and wires, then follow the specific steps for removal and installation of the stator assembly, distributor shaft, and other components. Check for wear or damage and replace any faulty parts as needed.

An intermittent no-start condition can occur where the engine starts momentarily and shuts down instantly or runs the duration of a trip but won't restart afterward.

Caution is given that the ignition module is a delicate and relatively expensive electronic component. Failure to follow the procedures could result in damage to the module or other electronic devices, including the EEC-IV microprocessor itself.
