Dear Pablo,
You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

Coil packs not firing on 2000 s type 3.0 jaguar


The coils have battery voltage running through the primary windings, and grounded in the ignition control module. The engine computer signals the ignition module when to cut the primary current, thereby inducing high voltage in the coil's secondary windings and spark at the spark plug.
The computer processes all sensor information, but primarily from the crank position sensor, to determine spark timing.

My 92 explorer has no spark


Hi, here are some tests you can do to diagnose the problem. Please let me know if you have questions.

First, use a voltmeter or 12 volt test light to check for power on the red wire going to pin 8 of the ignition control module when the key is on. The module is in the left front corner of the engine compartment.

If there is no power, the problem is the ignition switch or EEC relay. If there is power, next, check the ignition coil as listed below.

IGNITION COIL TESTINGPrimary and Secondary Circuit Tests
  1. Turn the ignition switch OFF , disconnect the battery, then detach the wiring harness connector from the ignition coil to be tested.
  2. Check for dirt, corrosion or damage on the terminals.

PRIMARY RESISTANCE
  1. Use an ohmmeter to measure the resistance between the following terminals on the ignition coil, and note the resistance:

Except 2.3L, 2.5L and 5.0L engines


B+ to Coil 1 B+ to Coil 2 B+ to Coil 3
The resistance between all of these terminals should have been between 0.3-1.0 ohms. If the resistance was more or less than this value, the coil should be replaced with a new one.

SECONDARY RESISTANCE

Fig. Fig. 1: Engine ignition coil harness connections-3.0L and 4.0L engines

  1. Measure, using the ohmmeter, and note the resistance between each corresponding coil terminal and the two spark plug wire towers on the ignition coil. The coil terminals and plug wires towers are grouped as follows:
Except 2.3L, 2.5L and 5.0L engines

Terminal 3 (coil 1)-spark plugs 1 and 5 Terminal 2 (coil 3)-spark plugs 2 and 6 Terminal 1 (coil 2)-spark plugs 3 and 4

If the coils test good, move on the the crankshaft sensor.
Using a DVOM set to the DC scale to monitor less than 5 volts, measure the voltage between the sensor Cylinder Identification (CID) terminal and ground by backprobing the sensor connector. If the connector cannot be backprobed, fabricate or purchase a test harness. The sensor is okay if the voltage reading varies more than 0.1 volt with the engine running at varying RPM. (check both the blue and gray wires at the ignition module with the engine cranking.)

If there is power and both the coils and sensor check good, replace the ignition control module.

Where are the spark plugs located on the 2000 s type jaguar? Also where can I get a repair manual for this make and model?


When you ask for information about your 2000 Jaguar S-Type, it would be very helpful if you would take a moment to mention which engine it is equipped with. There is a 3.0L V-6 and a 4.0L V-8 engine available for that make and model.

However, the spark plug replacement is similar except that the intake manifold must be removed to access the plugs on the right bank on the V-6 engine.

The spark plugs are located under the cover that goes down the center of each valve cover. You must remove the plastic engine cover to see the cover that goes down the center of the valve covers. Remove the screws in the cover plate. Remove the electrical connectors for each ignition coil. Remove the screws securing the coils and remove the coils. The spark plugs are located at th bottom of the hole that the coils just came out of.

NOTE: The spark plug tubes should be blown out with compressed air before removing the spark plugs. Failure to do so can cause severe engine damage from debris falling into the combustion chamber or contaminating the spark plug hole threads.

As for finding a service manual, the best recommendation I can give you is to subscribe to the service information available at ALLDATAdiy.com. This is the same infomation that I use as a professional auto repair technician. The fee is extremely reasonable - under $30 (US) per year.

I feel a misfire but there no codes stored on the ecm


More than likely you need new spark plugs, or you have a bad Coil on plug. To test each coil on plug, read the following:
  • A commercial coil tester, available from many tool suppliers, is an excellent way to test suspect coils. If the coil can generate a spark on the tester, the coil should be in good condition.
  • An ohm meter can also be used to test coil winding resistance. Primary-side resistance, from coil minus to coil plus, is typically between 0.3 and 1.0 ohm on electronic ignition type coils.
  • Secondary resistance values vary widely, so consult a specifications chart for the engine you are servicing. If a spec chart isn't available, compare secondary readings among all the coils to see if any one is higher than the others. A high resistance indicates deterioration in the wiring. Surprisingly, a coil with high resistance may still fire the spark plug, but the voltage produced will be higher because the current must jump the open wiring in addition to jumping the spark plug gap.

What should a multimeter read on a continuity test on the coil packs? i'm getting 1.9,1.7,1.7


The multimeter can read the resistance and if it is not open or shorted out, I'd say that your readings are in the normal range, comparing each resistance with each other + or - 10%.

I looked up the resistance readings on my online resource, but they did not list it specifically.
---
I looked up the following on autozone.com:

There are 3 dual-tower ignition coils that are part of the ignition control module (ICM). The ICM contains coil driver circuits that command the coils to operate. The Powertrain Control Module (PCM) controls each dual-tower ignition coil by transmitting timing pulses on the ignition coil control circuit to the ICM for the proper coil to enable a spark event.
  1. Inspect the spark plug wires for proper orientation.
  2. With the ignition OFF, remove the fuel pump relay.
  3. Crank the engine and test for a strong spark on each cylinder spark plug wire using a suitable spark plug tester. Ground the companion cylinder spark plug wire of each cylinder when it is tested.

    If a strong bright blue spark is present on all of the cylinders, remove and inspect all of the spark plugs for proper torque, proper gap, wear, damage, and fouling. Replace the spark plugs if necessary. If there is no spark on any of the cylinders, test the ignition voltage circuit of the Ignition Coil Module (ICM) for an open/high resistance or short to ground, or test the ground circuit of the ICM for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If there is no spark on any of the cylinders, or spark is weak or intermittent, test the IC circuit for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If spark is present on one or more of the cylinders, inspect and test the spark plug wires for arching, cuts, rubbing on other components, and proper resistance. If all tests are normal, then the system is operating correctly.

Where do I find the spark plugs on the Jaguar S Type 2L year 2000 engine.?


hey familyvanark,

Your spark plugs are located under your ignition coils. The first three are located on the passenger side underneath the three ignitions coils, im pretty sure the coils are held on my an 8mm bolt. The other three are on the driver side, and are located under the intake manifold, that big medal thing on the top on your engine and white in color. That HAS to come off to get to the other three spark plugs. Other than that take those three coils off and you'll see them.
