If you're seeing spark at the ends of the spark plug wires where they attach to the spark plugs, you most likely have a cracked or worn boot on the wires. It's also possible that the wires aren't tightly connected to the spark plug wires. Pull the ends off (1 at a time) and re-attach to the spark plugs. You should feel a small "click". This would be an indication that you've got a secure connection. If the wires are all tight and you still see sparks, I'd go ahead and replace the wires.

SOURCE: 1992 Isuzu Rodeo Distributor wires 3.1L engine

Hi,
Isuzu seem to have complicated things by changing engines, firing orders and even direction of rotation! As you can see, they've numbered the cylinders the other way than the 3.2L.

The Firing sequence for the 3.1 (traditional distributor) 6 cylinder is as follows -

d6e5b2a.jpg

If you take the distributor cap off, there should be a "No.1" formed on the inside. Stick a lead on this before you put the cap back on and go from there.
As leads are different lengths, you may have to swap a few to find the best fit.

I think 2 of them will look out of place - but that's the way it's designed. Just make use of clips for holding them neatly.

Thanks for using Fixya.

Changed the spark plugs in my 2002 Suzuki xl7 and now it won’t stay running. Drove fine before I changed plugs. Sounds like it is missing.


Did you set the gap on the new plugs to factory settings before putting them in? If not, they may not be the right gap.

Also, any number of other issues are possible such as:
1. Wrong plugs
2. Damaged wires when removed from old plugs
(Plug connector wires can be easily damaged when removing from old plug if just pulled off and special tool isn't used.)
3. Stripped threads on plug allowing gas blow by and poor compression.

No. (2) seems to be the most likely cause without knowing anything else. A new set of ignition wires after 15 years of service is not something frivolous to do and money well spent.

After replacing my distributor on my 89 toyota corolla it wont start


It is possible that if you replaced the distributor, you simply have the plugs in the wrong firing order. Another possibility is that you need new spark plugs, wires, plugs, distributor rotor and possibly a distributor cap. A long shot problem is the ignition coil, but since you have spark in one plug, it is unlikely.

Truck is not firing on 3 cylinders yet it runs.. Runs really rough, back fires, under powered.. Plugs are Wet, Firing order is correct. New Spark plug cables. Don't know that is wrong! Please Help


Check for spark at the plug ( may have coil problem).
If spark is good then do a compression check. Pressure shouldn't be less than 75% of known good cylinders.

Does anything get messed up if ive tried to start honda civic lx with spark plug wires in wrong order i tried about 10 times to start


correct the plug wires, and you should be fine. if anything possibly would get messed up it would be the cap or rotor, ot may have (carbon tracked due to cross fireing),but not likely. again place wires in correct firing order and shld be ok.

I changed my spark plug wires and possibly have them connected wrong. Is there a schematic that I might follow in order to ensure they are connected correctly?


FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1988-95 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g01.gif
Fig. 2: 1996-98 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g02.gif

2004 KIA OPTIMA WON'T START AFTER SPARK PLUGS WERE CHANGES


HI. There are several areas of concern here. I will list them below. Check all areas stated in the list for faults.

Possible cuases:

1. Incorrect firing order set. On the 2.0, 2.4 and 2.7 engines. These engines are equipped with a distributor-less ignition system. This system incorporates a coil pack assembly, along with wire sets. In order for the assembly to fire correctly, the order of the wires must be set to the proper sequence. if not, the engine will not turn over, or start correctly. Make sure your firing order is correct, and make sure you have not placed a particular wire set into the wrong cylinder. I will post a picture of the correct firing order for your engine, below this list, shortly.


2. Incorrect spark plug gapping procedure. If the new spark plugs were gapped incorrectly, this will not allow for proper spark, thus, preventing optimal combustion, due to lack of fire. Check the spark plug gap using a wire gap gauge, and adjust if necessary. The gap should be 0.039-0.043 in. (1.0-1.1mm)

3. Failed coil pack assembly. This will be the worst case scenario. The coil pack supplies the necessary current that fuels each plug. The current is transferred, via wire sets.This will be the culprit if all the above areas are proven to be operational, and in good shape.

4. Failed wire sets. Replace the wire sets if faults are found at the connector at the ignition coil pack, or at the plug boot.



NOTE*
In order to provide the correct firing order for your engine, i will need the engine size and liter information, if possible. Please post this information, asap. Thanks..

Rewired ford taurus spark plugs and when turns on it jumps what could i have done wrong?


If you replaced the distributor cap then there is a high possibility that you put the wires in the wrong firing order on cap.

If all you did was replaced the plugs, then I would pull each one out and recheck the Gap sizes with a feeler gauge. Also check to see if the spark/coil plug wires are touching metal or each other, which can cause the spark to arc out of the wire and never get to the spark plug. If I suspect an arc and do not see a physical problem, I wait until nighttime and look under the hood while engine is running...they stick out like a sore thumb. Also make sure that you did not put the wrong plugwire to the wrong spark plug.

When you change your plugs, you should also replace wires, cap and rotor.
