I would try the spark plug wires themselves before anything else, I doubt very much that you need a harness, that is very, very rare. If the plug wires don't do anything, I would find a computer and borrow it to see if it does anything. Check out the plugs too while you are at it. Hope this helps.

Spark plugs


Check this SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.

IGNITION COIL(S) REPLACEMENT
REMOVAL PROCEDURE
1. Remove the air cleaner resonator and outlet duct.
2. Disconnect the engine wiring harness electrical connector (1) from the oil pressure sensor (2).

6. Disconnect the engine wiring harness electrical connectors from the following:
• The engine coolant temperature (ECT) sensor (1)
• The fuel injector harness (2)
• The ignition coils (4)
• The heated oxygen sensor (HO2S) (5)
7. Disconnect the engine wiring harness electrical connector from the intake camshaft position (CMP) sensor.
8. Carefully disengage the engine wiring harness conduit from the camshaft cover, and position aside.

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.

jturcotte_2441.gif
jturcotte_2440.gif

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


jturcotte_2439.gif

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.)



jturcotte_2442.gif

Fig. Fig. 3: CKP sensor wire harness connections for the 4.0L (VIN X and E) engines


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

Engine light on. went to auto parts store, they diagnosed number 2 or 3 cylinder not firing. prior to this i changed plugs and wires. then i changed the coil. the engine light went off and the gas economy...


Hello mikew564.The first diagnosis was number 2 or 3 cylinder not firing. Once you changed the coil, the check engine light went off. When the light came back on again, did you get it diagnosed again to find out if the problem was the same?... 2 or 3 cylinder not firing????

First of all, there is NO extra wire/ground on the coil/ignition wiring (see images below). The spark plugs and ignition plug wiring can be checked for arcing, corrosion, resistance and can be checked for cracks in the insulators or worn electrodes (and spark gap) by a competent mechanic.
If you are having the same issue (2 - 3 misfire), there are several techniques for eliminating the plug wires or spark plugs. Spray water on the plug wires to see if they are arcing. Swap plugs from cylinders 2 & 3 with cylinders 1 & 4. If you still have a 2-3 misfire, check/inspect/examine the coil connector pins & coil harness to the coil(s) themselves.

If the coil pack did not resolve the issue you are experiencing, then you may either have an injector issue, or a faulty PCM-powerterain control module, also known as the vehicle's computer.

How do you remove the ignition coil


Each ignition control module (ICM) has the following circuits:
An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.
