  Q: How to remove and install an ignition coil for Pontiac Fiero?

  A: Disconnect the cable from the negative terminal of the battery. Unplug the coil high tension wire and both electrical leads from the coil. Remove both mounting nuts and remove the coil from the engine. Check the coil for opens and grounds by performing the following three tests with an ohmmeter. These three resistance checks will determine whether your separately mounted coil is good or bad. Using the ohmmeter's high scale, hook up the ohmmeter leads as shown. The ohmmeter should indicate a very high, or infinite, resistance value. If it doesn't, replace the coil. Using the low scale, hook up the leads as shown. The ohmmeter should indicate a very low, or zero resistance value. If it doesn't, replace the coil. Using the high scale, hook up the leads. The ohmmeter should not indicate an infinite resistance. If it does, replace the coil. Installation of the new or old coil is the reverse of the removal procedure. Remove the distributor. Turn the four latches and remove the cap and coil assembly from the lower housing. Connect an ohmmeter to both terminals of the cap coil assembly. The reading should be zero, or nearly zero. If it isn't, replace the coil. Connect the ohmmeter between each of the terminals of the coil assembly and the center contact of the cap. Use the high scale on the ohmmeter. Replace the coil only if both readings are infinite. Remove the coil cover attaching screws and lift off the cover. Remove the ignition coil mounting screws and lift the coil; with the leads, from the cap. Remove the ignition coil arc seal. Clean with a soft cloth and inspect the cap for defects. Replace if necessary. Assemble the new coil and cover in the cap. Install the distributor cap. Install the distributor in the engine.

  Q: How do you replace the pick-up coil for Pontiac Fiero?

  A: Start by removing the cap and rotor of the distributor, then remove the distributor itself. Disconnect the pick-up coil leads from the module and use an ohmmeter to test for any faults. There is a need for flexing by hand to identify intermittent opens on the leads with infinity reading at all times on the ohmmeter. Then, connect one end of an ohmmeter to the pick-up coil lead terminal and flex it again checking for intermittent opens as it flexes, with a constant meter reading of 500-1500 ohms. If any of these tests fail, it means that there is a bad pick-up coil. To replace it, mark the distributor gear and shaft for reassembly in the same position, take out roll pin from distributor shaft and gear, and pry off retaining ring. Pull straight up on pick-up assembly and wipe distributor base and module clean before applying silicone lubricant between module base for heat dissipation. Drop in module attaching module base then connect pick-up pole piece assy., retainer assy., install shaft gear parts, roll pin. Ensure that teeth do not touch; after this install rotor/cap then final re-installation of distributor into engine must be made. For V6 remove distibutor from engine; disconnect wiring connector at cap; turn four latches to remove cap/coil assembly from lower housing. Take out rotor and pickup coil lead wires from ignition module. When testing an ohmmeter should be connected between pickup coil lead connector & distributor housing reading infinite resistance. Connect an ohmeter between both terminals of pickup coil lead connector and note steady values between 600-1600 ohms will indicate that you have good ones. If any of these tests fail, it indicates that there is something wrong with its pick-up coil. To replace it: mark distibutor shaft/gear for reassembly; drive out roll pin; remove gear then draw shaft out of distributor. Next, remove the magnetic shield by removing three attaching screws, followed by detaching pick-up coil, magnet and pole piece by taking off C-clip. Put back a new pick-up coil, magnet and pole piece with a thin washer, then reassemble the shaft/gear parts/roll pin making sure teeth do not touch. Inserting rotor/cap then finally reinstalling distributor into engine that is all.
