S10 , 98
all books show this, even chiltons and haynes
or online
or alldata dot com
or Chev. real FSM
all.
and more than one engine, (typical for all cars)
4.3L LF6 or L35?

if you dont know,? the look in book for clues.
if no books? then open the glove box, see GM RPO tag
see that , find the Engine code. now you know.
GM RPO codes are easy to find using Google.ALL GM products.

now the other way
you open hood
you see the spark plugs, see them , they are attached to coils
or a dizzy. just look. ?
dizzy has cap and 6 wires. COPS has 3 or 6 COPs
dizzy or COPS x6 or 3 if wasted spark cops.
now you know the 3 systems (a general answer)
im must guess, as i dont know what engine you have.

Where is the coil located


What is the year your legacy.
Normally the ignition coil is located on the top of the engine. Just follow the spark plug wires to where they plug into the coil. If replacing make sure to draw a diagram of where the wires went into the old coil.

Cylinder 1 is not firing


Instructions1 Use a wiring diagram for the year model of your vehicle. Locate the terminals running into and out of the ignition module. Placement of the module varies from model to model so check the appropiate service manual of your vehicle for the exact location.
2 Turn the ignition on and use your DVOM to check for voltage to the ignition module and the positive terminal of the ignition coil. Place the negative lead of your DVOM to a solid ground and use the positive lead to probe the wires running to the ignition module and to the ignition coil.
3 If your DVOM shows that voltage is present at both locations, remove the DVOM leads and set the meter aside. Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
4 If your test light does not flicker on and off, visually inspect the wires running into and out of the ignition module. Look for burn marks, melted wire insulation and breaks in the wires. Use your wire splicing tool to remove the bad area in the wire and use your wire connectors and splicing tool to repair the faulty wires.
5 Use your DVOM to check for an open circuit condition in the primary coil winding. Touch the negative probe to the negative terminal on the ignition coil, touch the positive lead to the positive terminal. Set the meter to read ohms. If the reading shows infinite ohms, your ignition module is faulty and should be replaced. Follow the service manual instructions for replacing your ignition coil.
6 Look to see if the DVOM test shows low to no ohms; if so, then you have a faulty ignition module that will have to be replaced. Follow the service manual instructions for your vehicle to replace the module.
Thanks

SKIPPING PROBLEM . SPARK PLUGS & WIRES HAS BEEN DONE. THERE'S NO 12 VOLTS AT THE COIL CONNECTOR PLUG WITH THE KEY ON. LYMAN


Sound like a ground problem; the fastest way to identify the Power and Ground Circuits is using a wiring diagram. If you don't have one you'll have to find out by trial and error as you probe each circuit.

The power circuit is tested with the Key On and Engine Off. Place one end of your multimeter or Test Light on the Battery Negative Terminal and with the other end, probe the Power Circuit. Turn the Key to the Run position. If the Power Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up. Here are the possible results:
* You got 12 Volts on the Power Circuit
Good, this is a good sign. The next step is to check the Ground Circuit of the Coil on Plug connector that you're testing.

* No Power in only one Ignition Coil
Without 12 Volts, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Power the new one will not Spark.
Since the Power Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Power Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Power at any Ignition Coils
The fuse or relay that supplies this voltage is blown or BAD.
You'll have to consult your Repair Manual's wiring diagrams to see where this fuse and/or relay is located and replace as necessary.
After replacing the blown fuse or the defective relay. Retest the Ignition Coil.

Them, the Ground Circuit is tested with the Key On or Off. It doesn't matter because this is a Chassis Ground. Place one end of your multimeter or Test Light on the Battery Positive Terminal and with the other end, probe the Ground Circuit. If the Ground Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up.

* You got Ground
Good, now the next step is to verify that the Coil-on-Plug Ignition Coil is receiving the Triggering Signal. This info belongs to the next section of this article.

* No Ground in only one Ignition Coil
Without this Ground, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Ground the new one will not Spark.
Since the Ground Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Ground Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Ground at any Ignition Coils
This usually happens thru' human error in most cases and is a very rare thing. Usually the engine was replaced and this ground was not re-attached.
You can Ground this circuit with a jumper wire. Jumpering to Ground just one Coil-on-Plug Ignition Coil should provide Ground to all of them (consult your Repair Manual's Wiring Diagrams to be sure).
With this jumper wire to Ground attached, crank the vehicle.
If in fact the Ground Circuit does have an open short, this (the jumper wire to Ground) should make the vehicle start, or at least get the Ignition Coil to Spark.
Repair the open short and retest for Spark or retry starting the vehicle.


Hope this helps. Keep us updated.

What is the firing order for a 2005 nissan titan crew cab? Which one is cylinder one and where can I find it? PLEASE HELP!!!


The firing order is 1-8-7-3-6-5-4-2 and the #1 cylinder is located at the left front of the engine and the spark plug and ignition coil for the #1 cylinder will be the first ignition coil and spark plug on the front of the left side of the engine on top of the valve cover, and to remove an ignition coil dis-connect the wire connector to the ignition coil, then remove the bolt securing the ignition coil (usually this is one 10 mm bolt) and give the ignition coil a twist as you pull it straight up and out of the spark plug well, and if you are removing the spark plug then use a socket with an extension and swivel to loosen up and tighten the spark plug, but use about a 6 inch length of 3/8 inch fuel line pushed onto the spark plug to actually remove the old spark plug and also to start the new spark plug down inside of the spark plug well to reduce the possibility of cross-threading or damaging the threads for the spark plug. Here are some images to assist you and the ignition coil location image shows the right side of the engine for reference, with cylinders 2-4-6-8 and this was just the best image that I could find to make that diagram, however they are laid out the same on the left side of the engine 1-3-5-7, and let me know if you require any further assistance.

Were is the ignition module located at do you have a pic or diagram


Ignition control module is located under the ignition coil packs, follow the spark plug wire''s from engine to coil packs.
If you have a 3.1L engine, the module will have three connector, two one one end and one in the other end.
If you have a 3.8L engine, the module will have one wide connector on one end only.
To remove module, remove all three coil pack's, will have two small screw's to each one,disconnect elec. connector from module and unbolt module.

Ignition coil e


The ignition coils are listed from 'A" to "L" (up to 12 cylinders) and they are in sequence according to the firing order. This diagram will help you out, and according to this diagram for your vehicle, "E" is the fifth letter so the fifth cylinder in the firing order is cylinder #6, and as you can see from the diagram that coil "E" or cylinder #6 is the second spark plug or cylinder from the front on the drivers side of the engine.
