Sparkplug ignition coils

How can I test the ignition coils for a Ford Escape V6 3L with individual coils. I need the resistance values to verify functionality. It is not giving any bad code at the moment. Spark plugs were change. Starts OK, but when the gas pedal is pressed the engine stalls and dies. Any suggestion will be appreciated. Thanks in advance

    The six coils were verify and three were soaked with water and got heavy oxidation. New coils were intalled and the stalling was resolved, since the coils were grounding. Thanks M. Santiago for your help.!!!

    Replaced the PCM and one bad coil about a month ago. Car ran good for 4 weeks then suddenly died. Acts like its not getting fuel, but test shows the code 1351.

    can the ignition coils cause the PCM to go bad or can the coils go bad and not effect the PCM i am getting code P 01351

Why is it my 2008 chevy uplander rear wiper motor/blade moves some and stops. I let van set 5-10 minutes with key off. Turn on key. Wiper motor/blade moves a few degrees and then stops again. Why?


Can you move the wiper by hand ? Which does your vehicle have ?
WDA/Z88 The rear wiper is controlled based on an input from the rear wiper/washer portion of the multifunction switch. When closed, the wiper ON and wiper DELAY switches provide a unique voltage signal to the rear window wiper motor indicating the desired speed. Each switch has a unique resistor that drops the voltage to a specified value which is interpreted by the rear window wiper motor as ON or DELAY. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).
W49 The rear wiper is controlled based on an input from the rear wiper/washer switch. When closed, the wiper ON switch provides a voltage signal to the rear window wiper motor indicating rear wiper operation is requested. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).

I have a 2001 roadking police bike. it has no spark. the bike cranks fine the fuel pump works, I checked all fuesess relays. checked the ckp sensre for metal ,checked the pickup senser metal. checked




Are the plugs installed because without compression you will not get ignition/spark.

Are there any codes set???

Is the ignition fuse okay??? Is ECM fuse okay?

Of course first you need power to the coil which should be there whenever the ignition and run switches are on if so see below:


Are the plugs installed

Remove the coil. THEN set your ohmmeter scale to RX1 and place ohmmeter leads on the primary coil windings A (front of coil) to B (middle of coil), B to C (front of coil) and check for primary coil winding resistance which normal resistance range is 0.5-0.7 ohms. If primary resistance is not within this range check out test results below.


Ignition Coil Secondary Circuit Test

With the ignition coil removed from the motorcycle and the ohmmeter set to the RX1K scale place the ohmmeter leads on the secondary coil windings B (middle terminal) to

R (rear secondary terminal/socket), B to F (front secondary terminal/socket) and check for secondary coil winding resistance which normal resistance range will be 5.5-7.5K ohms. If secondary resistance is not within this range check out test results below.


Test Results

A low resistance value indicates a short in the coil winding which requires coil replacement.


A high resistance value might indicate that there is some corrosion/oxidation of the coil terminals requiring the coil terminals to be cleaned and the resistance test then repeated and if after the test is repeated the resistance is still high after the terminals were cleaned the coil must be replaced.

If there is an infinite ohms or no continuity) resistance value the coil is open and must be replaced.


If you have spark, it sounds like either the sensor in the timing cavity of the engine is bad or the electronic ignition unit is bad.

I recommend a diagnostic scan to confirm my diagnosis of a malfunctioning coil(s).

How to Test and Replace Ignition Coil on BMW 3 Series


The following procedures apply for BMW 3 series (6-cylinders engine) 1992 - 1998 model years. To Test and Replace the Ignition Coil, do the following:
  1. Remove plastic engine covers from top of engine by prying off nut covers and removing cover mounting nuts.
  2. Disconnect harness connector from coil. Connect multimeter between terminal 15 (+) in connector and ground. (use a digital multimeter for the following test). See Fig.1. below BMW 3 series coil harness
  3. Turn ignition on and check for battery voltage. If battery voltage is not present, check wire between terminal 15 and ignition switch. The wiring to terminal 15 (+) of the coil (via the ignition switch) is not fuse protected. Use care when testing this circuit.
  4. Turn ignition off.
  5. Use a multimeter to test coil primary resistance at coil terminals. (primary coil terminals: 1 (-) and 15 (+), primary coil resistance: 0.4-0 .8 ohms; secondary coil terminal and resistance: NA).
  6. Remove coil and inspect coil housing for hairline cracks or leaking casting material . A leaky ignition coil may indicate a faulty engine control module (ECM). Check ECM before installing a new coil.
  7. When replacing ignition coils, ensure that the replacement coil(s) are from the same manufacturer containing the same part code numbers. If individual coils with the correct specifications are not available, all coils should be replaced.

What is the spark plug setting for izuzu axiom 3.5 v6 my car is hard starting at 152000 miles, i replaced the timing belt flushed the injectors replaced fuel filter


Hi. You will need to Adjust each spark plug gap to 0.031-0.035 in. (0.8-0.9mm). With that said; i would check the status of all the ignition coils that are on top of each plug. Your engine is equipped with a COP coil design. Each plug will have its own individual coil on top. Each coil can be tested for proper resistance levels. You may have one or several bad coils that are malfunctioning. If these coils have not been changed, I would recommend to test each one to be sure that they are functioning at a high level.

Here is a simple testing procedure to verify that your coils are functioning as designed. A weak coil will cause a very hard start situation. Follow carefully:

1.First you will need to check the ignition coil assembly for insulation. Check terminals for corrosion or damage, and replace as necessary.

2. Next; Gather you ohmmeter or multimeter and measure the resistance of ignition coil assemblies and compare with the following specifications:

a. Terminal 1 to 2: Without 0 ohms or infinity maximum ohms.

b. Terminal 1 to 3: Without 0 ohms or infinity maximum ohms.

c. Terminal 2 to 3: Without 0 ohms or infinity maximum ohms.

3. Now; If the measured values exceed the specifications listed above, the ignition coil must be replaced.

Multiple Ignition coil failure w/ On-board computer failure


This is a common problem on most Ford products since around 1998. The issues is mostly with the COP--Coil-On-Plug. Their individual coils for eack spark plug,vs. a single coil pack or distibutor and wire type system. Now the good part. With all of fords problems, ALL MFG's use this type system,Nice move.
The coil driver failure, shouldn't be a wide spread issue
Forget recalls?

You saw Nissan ,recall issues,back to 2004 thru 2008,once Toyota had the gas peddle issues. If it wasn't for Toyota,they were laying low. Everyone new there were problems. Same thing on Chevy Colorado,Etc

1993 ford ranger no spark


The first thought that comes to mind is to check the ignition system, but to correctly check you will need certian meters. ALSO because of the extreme high secondary voltage produced by the ignition system you must be very carefulwhen performing this test.
The first thing you will need is a "calibrated ignation tester", you can buy one at most auto parts stores. You can get several different types so make sure buy one that can be calibrated for the high voltage ignition system.
Disconnect any sparkplug wire and then attach the calibrated tester to the plug wire. Then you have to clip the tester to ground source on the engine, like a bolt or a metal bracket. Then have an assistant crank the engine over while you watch the tester looking for a consistent bright spark. If you get a spark that means enough voltage is present to reach the sparkplug and fire it. Now do this to the next plug and so on until you've checked them all. If you are getting spark that means you ignition coil pack is good and your problem may lay with your sparkplugs.
NOW. If you don't get spark, or it's not a consistent spark you next need to check the sparkplug wires. First you can try swapping them or better yet use an ohmmeter and check for continuity and resistance in the wire. Rule of thumb is for every foot of sparkplug wire there should be 5000 ohms of resistance.
Now if everything so far has checked out to be OK you need to check the battery voltage at the ignition coil. To do this disconnect the coils electrical connector turn your key on, but not cranking your engine, attach a regular 12 volt test light to the connector. If it doesn't light up check the fuse that protects the ignition circut. If it does light up next you can check the primary and secondary resistance of the coil pack. If all of these things check ok your problem may be what is known as a crankcase position sensor. To test this is hard to explain, but I'll try. Take a LED test light and hook the wire up to the positive + side of the battery. Next using the probe end you have to check all of the negitive terminals on the ignaition coil harness. What you are looking for is a flashing of the test light while an assistant turns the key on and cranks the engine.
If no problem is found you will probably have to take your vehicle to a qualified shop and have the PCM checked out.
I hope this helps you.

omh is actually ohms whis is the measurement of resistance in an electrial circuit, with a multimeter you would set it to the ohms side of the dial and put the leads (one on each side) to the connections of each side of the coil, then you should get a resistance or ohms reading. you will need to consult ford to establish the maximum amount of resistance allowance per each coil, if it is too high it will need to be replaced!! hope this helped!!
