Plugs and wires 2005 mercury sable


What engine do you have, I will assume a DOHC V6, the DOHC V6 doesn't have spark plug wires, each spark plug (located under the igntion coil) has its own separate ignition coil, it is called direct ignition. You unbolt the coil and remove it with the attached spark plug boot and then you remove the spark plug from the cylinder and replace, do one at a time.

I need help locating a module ignition modulator in a 2003 Chevy Tahoe


Who told you that one ? Module ignition modulator 2003 Chevy Tahoe ! No such thing! Your best bet would be to take your vehicle to a qualified repair shop .
The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.

Location of ignition control module 2001 cadilac deville


Ignition Coils/Modules
The electronic ignition system uses an individual ignition coil for each cylinder. There are two separate ignition module assemblies located in the camshaft cover of each cylinder bank. Each ignition module assembly contains an ignition control module and four ignition coils. Each ignition coil connects directly to a spark plug using a boot. This arrangement eliminates the need for secondary ignition wires. The ignition module assemblies receive power from a fused ignition feed. Both ignition module assemblies connect to chassis ground. A Reference Low and four ignition control (IC) circuits connect each ignition module assembly to the PCM. The PCM uses the individual IC circuits to control coil sequencing and spark timing for each ignition coil. The IC circuits transmit timing pulses from the PCM to the ignition control module to trigger the ignition coil and fire the spark plug. The PCM controls ignition system sequencing and timing events

How to change plugs on 02 kia sportage

    Keep a regular schedule for inspecting the spark plugs on your 2002 Kia Sportage. According to the official 2002 Kia Sportage owner's manual, spark plugs and ignition wires should be inspected every two years or 48,000 miles, whichever comes first.

  • 2

    Let your 2002 Kia Sportage sit for a few hours before opening the engine compartment. You want to make sure that the engine is cool before you begin working on it.

  • 3

    Pop open the hood of your Sportage and locate the ignition wires, which will be attached to the top of your engine. The 2002 Kia Sportage has a four-cylinder engine, meaning there are four spark plugs each attached to an ignition wire. The ignition wires run from the engine to the fuse box, which is located in the left side of the engine compartment.

  • 4

    Inspect the ignition wires of your 2002 Kia Sportage. These wires will need to be replaced if they appear worn.

  • 5

    Disconnect the ignition wire to your spark plugs. Grab the rubber boot located near the base of the wire and pull upward instead of yanking on the wire. Remove only one wire at a time, or mark the wires with a colored Sharpie marker before disconnecting all of them. Improperly reconnecting the ignition wires can seriously affect the performance of your Kia Sportage.

  • 6

    Attach the spark plug socket to your socket wrench. Use the socket wrench to remove the spark plug from the top of the engine's cylinder.

  • 7

    Inspect the spark plug. There will be some soot, but if the spark plug is completely covered in soot, it needs to be replaced.

  • 8

    Position your replacement spark plug in place and secure it with the spark plug socket on your socket wrench. Be careful not to overtighten the spark plug after it has been snuggly fitted.

  • 9

    Position the rubber boot of the proper ignition wire in place above the spark plug and insert it with your hands. Close the hood of your 2002 Kia Sportage

    Changed coil and distributor cap, still my engine has no spark


    Here are 2 things to check. With the distributor cap off crank the engine. Does the rotor turn? If it's not turning you may have a broken timing chain. If your timing chain is ok then the problem may be the ignition module. This is usually located at the base of the distributor and it will have several wires running into it. The ignition module converts the DC battery voltage into an AC voltage that the ignition coil transforms up to a much higher voltage that will be sent out to the spark plugs through the distributor. I hope this helps you out.

    Where is my spark plugs located


    the spark plugs are located under the ignition coils. Look on the top of the engine and on either side of the throttle body you should see 4 round ignition coils with a two wire harness coming from each. Each one has an 8mm bolt holding them down. remove the bolt on each one to gain access to the plug.... One word of caution though remember which coil goes in which hole or better yet just do them one at a time.
