Remove the two bolts that hold it in place. *This must be done gently but firmly to avoid snapping them off* After the successul removal of the bolts the coil is simply lifted off and the spark plug can be removed without detaching the electrical connection to the coil.

From 1991 to 1995 with the EEC-IV system there is an external ignition control module mounted on the radiator support in front of the battery. Remove the battery in order to change the module. 1996 and newer with the EEC-V system, the ignition control module is incorperated into the powertrain control module (PCM) that is visible from the engine compartment, in the firewall, on the passenger side.

the ignition module on a buick park avenue is under the coil pack which is on the front left side of motor. its where the plugs plug into coil pack. the ignition module is the part that is underneath the coil pack. You will need a star tool to remove the 6 star screws. in order to remove the whole thing their are 3 i belive 7mm nuts under neath the whole thing these also need to be removed. you then unplug the coil pack from the ignition module in order to replace it . be sure to get the wires hooked up in sequence or it may not start.

First disconnect the negative battery cable then make sure engine is cool before you do the next step, disconnect the cooling fan then remove then remove the four bolts that hold the fan in, remove the upper radiator support mount, jack the car up, make sure you put it on jack stand, there is a bolt on the bottom of the ignition module mount, you have to remove that from under the car, then remove spark plug wire make sure you label them before you remove them because if you don't you will change the firing order and you car may not start or run right if you don't them back in the correct firing order, OK now disconnect the ignition connector then remove the two bolts, one on each side, then remove the ignition module with the coil pack. installation is the same as removal. Good luck.

Look behind the red colored dipstick. You will see 2 ignition coils side by side (the spark plug wires connect to them) these are mounted on top of the ignition module. Each coil connects 2 spark plug wires. The coils have 2 bolts that hold them to the block. Disconnect the 2 plugs at the top of the ignition module. Remove the bolts holding the ignition coils to the ignition module and the whole assembly will come off.When replacing the coils, the spark plug order from left to right is 4-1-2-3 (the cylinder order on the block from left to right is 1-2-3-4).

The distributor has a module that sends the current to each spark plug in its firing order. To get to the module one must first remove the ignition rotor. There is a plate that has two screws. The module is located under the plate. The module can be removed and be tested at a local parts store. The module can be purchased at most auto stores. It cost around $100.00.

The Ignition Module on this vehicle is located inside the distributor car. There are 2 sets of wires that plug into the distributor. The large wire connector is your ignition module. In order to remove the old one you must. . Unscrew and remove the distributor cap. Pull of the Rotor button in the center of the distributor. Remove the two screws on each side that holds in the plastic gasket that goes around the inside edge of the distributor. Once that is off.. there are 2 more screws that have to be removed that holds on the black distributor shield. Remove the Center screw that was underneath the rotor button. (Be sure not to strip that screw). Once the screw is out.. remove the contents but make sure to remember how it goes back together. Once the contents are removed.. there will be a very small screw that holds down a small metal contacter. Remove that screw.. slightly bend the contactor and remove the igniition module. Its alot simpler than it sounds. Good Luck!

Take out the distributor.Take off the cap. Take off the rotor. Undo the bolt holding the bob weights. Remove the 2 screws holding the vacumatic advance unit on the outside and manouvre off the advance mechanism inside. Remove the 2 screws holding the bottom assembly. Mark position and remove. Now the module... You will see a small coil surrounding the center spindle,it's attached to the module which is held by 2 screws and 2 wires attached (take care to replace the wires in the same order). Remove the screws and lift out the coil/module. The coil is attached to the module by 2 slide-in contacts. Pull the coil off the module and put it on the replacement module. Be sure to put the heat sink white paste that comes with the new module. Re-assemble.

The starter relay is out. Or the ignition module. Or the ignition switch is out. And its the odds in that order. Greatest to least.

Most Ford vehicles require you to remove the Air Bag module first, remove the steering wheel next in order to access the retaining screws on the back side of the the steering wheel. Most importantly if you intend to do this procedure, you must disconnect the battery first and then put the ignition key in the ignition and turn it on in order to discharge the electricity still left in the system.

A piezo is just a manual, mechanical type of module. In order to work as an ignition the piezo module will need to be wired to an electrode which will spark when the piezo module is pressed or cranked. An ignition system is an assembly of parts and the piezo is like a spark generator for an ignition that does not use batteries or electricity. Pressing or turning the piezo module will send electricity to the electrode which should be mounted where gas emits from the burner so the electrode sparking will ignite gas as the gas leaves the burner.

The ignition is now controlled by the PCM (powertrain control module), so the stand-alone ignition module doesn't apply to the WindstarHang-on, I found this little snippet:Only 1995-96 3.0L engines use an external ICM. 1997-98 3.0L and all 3.8L engines have the ICM incorporated into the Power Control Module (PCM).1995-1996 3.0l Ignition Control ModuleFrom the diagram in the Autozone Repair Guide, the module is mounted to the passenger side fender, just behind the engine coolant reservoir.Disconnect the negative battery cable, a plastic cover, couple of screws and a wiring connector. Pretty straight-forward.AnswerIf the question is about the location of ignition coil pack, on Ford Windstar 2001, it is located near the firewall under the cowl. In order to access it freely one has remove the plastic and metal cowl in front of the windshield.If the question is about ICM then from what I know is, it is part of PCM for the late models.

Possible reason there is no spark on a 1987 to 1990 Chevrolet Celebrity V6: This assumes that the spark plugs and wires are in good order and the ignition key is on. No power to the ignition module. Faulty ignition module. Faulty crankshaft position sensor. Faulty wiring or connectors. Faulty engine control module (engine computer) There may well be others, these are common causes I have seen.

The 2000 Chevrolet Corvette blower motor control module can be found behind the passenger side dashboard. You will need to remove the dashboard in order to access the module.

If I understand correctly, the Ignition Control Module is located inside of the distributor. To replace it remove the distributor cap, which is locted in the center rear of the engine compartment. If there is adequate room, leave the spark plug and coil wires attached. Set the cap aside and look for a wiring harnes on the bottom of the distributor. I should be attached to a small flat black module that has two small bolts holding it in place. Carefully remove the small bolts, and unplug the harness and remove the Ignition Control Module. Replace and assemble in reverse order. Make sure to get the distributor cap on the same way and do not rotate the distributor during the process.

With no key you will have to drill out the existing tumbler assembly from the switch in order to unscrew the ignition switch bezel.

Remove the distributor cap, remove the rotor, remove the two machine screws that hold down the module, wiggle module out of connectors. To install, clean area where module attaches, apply the silicone grease that comes with new module to the area under the module, wiggle module back into connections and thread in the two screws until snug. Reinstall rotor and distributor cap. Note, the distributor cap and rotor only fit one way. -------------------------------------------------------------------------------------------------------------- This is not a hard task if you are nimble enough to reach the back of the motor. First locate the distributor cap its close to the fire wall sticking up on the back of the motor. Remove the cap 2 screws 1 on each side (I do not take the wires off the cap it will lay off to the side, if you do not remember how they came off this is your firing order if its wrong the engine will not run or at best run poorly). Now you will see the rotor on top of the shaft remove it buy pulling straight up (it only goes on one way reinstalling will be easy) You may or may not have a plastic dust cover under that if so remove it. Now you have access to the ignition module small circuit board on the base of the distributor housing it will have a couple of wire leads Take care not to snap these off. Now remove 2 small mounting screws and your in buisness You should have dielectric grease provided with the new module spread it on the new unit where it makes contact with the distributor base and reinstall ever thing in the reverse order. AS ALL WAYS read any direction that come with your new part. Hope this helped and good luck Don

1)Remove ignition wires( marking them so you know which order to replace them), 2)remove 4 Allen head screws, 3)disconnect all wiring plugs. Reverse directions for replacement.

You must remove the steering wheel. There are some special tool that make this much easier.

follow your spark plug wires under the motor to the ignition module where the coils are mounted and the wires are attached to them. use a wrench and a screw driver to take off the module and the coils. do not lose the plug firing order.

There's a manual method of programming keyless entry transmitters also. Make sure that you have all the transmitters you want to be able to use handy because the system will have to "learn" each one, even if they already worked before.

First of all disconnect the battery before starting with the other steps. After this remove the lower steering column and the knee blocker reinforcement to be able to access the cables connecting the Body Control Module. Remove the two wire connectors which are located at the bottom of the module then unscrew the bolts that are holding the junction block to the mounting bracket of the dash panel. After this was done, remove the junction block itself and remove the screws that are holding the module to the junction block. Next slide the Body Control Module downwards out of the junction block. This will disengage the guide studs on the block. To install a new BCM module, do the above steps in the reverse order.
