How to check and replace the ignition control module on the Mercury Grand Marquis?

Duraspark II Ignition Control Module checks include verifying power, checking distributor stator resistance, and ensuring ground circuit continuity. If battery voltage doesn't reach the module, trace the circuit to the ignition switch and battery. Incorrect test results mean the module should be replaced, involving detaching the battery cable, unplugging connectors, removing screws, and installing a new module. TFI-IV Ignition Control Module checks include inspecting and reconnecting ignition wiring, testing the ignition coil circuit, and checking module power. Resistance checks should be performed between specific terminals. Incorrect results require module replacement, involving removing the distributor and module, and installing a new one. EDIS Ignition Control Module checks involve inspecting and reconnecting coil wiring, testing the coil circuit, and checking module power. Resistance checks should be performed on the crankshaft sensor. Incorrect results require module replacement, involving disconnecting the battery cable and electrical connector, removing screws, and installing a new module.

Mercury Grand Marquis Ignition Control Module

The Mercury Grand Marquis' Ignition Control Module precisely controls coil current in a split-second time frame so that each cylinder receives a hot spark when needed. The Ignition Control Module is located between the ignition switch relay and the coils. It receives pulses from a distributor reluctor or crankshaft sensor as appropriate and makes use of a high-speed transistor to open and close the primary circuit in order to generate 15,000 to 40,000 volts for the plugs. Some earlier models of Grand Marquis had a distributor-mounted Ignition Control Module that was dependent on centrifugal and vacuum advance, so base timing had to be set manually. In subsequent models of the Mercury Grand Marquis, the vehicle was equipped with a distributorless Ignition Control Module that was combined with the powertrain computer. This also allowed the software to handle all the advance decisions and therefore the vehicle saw a vast improvement in performance, fuel economy, and cleaner exhaust. If a Grand Marquis will not start and test light flicker is absent at the coil, suspect the module before wiring or sensors. Drivers of Mercury automobiles value the reliability their Ignition Control Module adds to every Mercury ride.
