Changing spark plugs

I believe i have the wireless style sparkplug system. Can't see any wires. Are the spark plugs on top of the engine under the square caps? Is it just a matter of disconneting the leads and bolt then pulling the caps off.

Where are the sparkplugs located


Plugs are on the top and if you take your time you can get these replaced yourself. I would suggest watching a YouTube video on the process first. That will help a lot. If you follow the wires to the boot you have reached the spark plug. It is under that boot. Just gently pull it off and it will expose the plug.

I drive a 95 toyota 4 runner.I would like to know the right way to check my sparkplug wires if working p roper.


You can fabricate a tester from a 6 inch long mongol pencil. Sharpen one end and drill a 1/8" hole in the middle. Now remove the sparkplug wire from each sparkplug and insert the pencil onto the sparkplug wire with the dsharpened end connected or touching the ground or any metal part of the engine. Start your engine and you should see sparks jumping on the drilled hole on the pencil which indicates that your spark plug wire is okay.

Welli have towncontry i change computer but dont start and the inyector dont have electricity to star the car


Is the computer powered up? Does your check engine light come on when you turn the key to on?
If that's o.k., check fuel pump operation. Do you hear the pump come on to prime the fuel system when you first turn the key to on? It should turn on for about 2 seconds, and then stop again until the engine is being cranked, at which time the pump comes back on. You can't hear the pump when engine is cranking or running, but you could hear it first come on to prime the system. There may be a schrader valve-a test port- on top of engine on the fuel rail. If you find it, take the cap off, and press down the valve-gas should shoot up if the pump is working and getting fuel to the engine.
Now if the computer is powered and the pump is getting gas to the engine, and still no start, you need to check your ignition system by checking for spark at one of the sparkplugs. Pull a plug wire off a plug, pull the sparkplug out, reattach the plug wire to the plug, and lay the sparkplug on a metal part of the engine, so the sparkplug threads are touching metal (grounding it). Now have someone crank the engine over while you watch the plug for a strong blue spark there. You need to see a blue, snapping spark to know your ignition system is good. An orange spark is not good-too weak. If no spark, or not consistent, you have a problem in the ignition system, and will have to diagnose and fix that.
If all is good so far, you may need to check the fuel injection system. Start by pulling one injector connector off, and check for power on one of the two wires going to the injector (the other wire is the injector ground wire), with the key in the on position. If no power to the injector with key on, the injector drive circuit has failed. If one wire does have power, post back to me for how to test the injector ground circuit-very easy with a testlight.
Good luck.

I cant find the spark plugs on my 1991 kia sportage


If your sportage has the 4 cylinder engine, there is a plastic cover over the engine that is held down by 4 bolts, one at each corner. Remove the bolts with a 10mm socket and lift he cover off and lay it aside. You will see the spark plug wires and the 4 holes where the spark plugs are. The spark plugs are about 4 inches down into the holes. Be careful removing the spark plug wires, they will be tight, and you will have to rotate them back and forth while pulling up to get them loose.

I need to change the spark plugs where r they located and which kind is the best for my car because there is a single pin and twin pin.


Hi! The sparkplugs are concealed with the top engine cover. YOu need to remove the top cover using a torx bit. Once removed you'll see the spark plug wires, pull the wires and you'll now have access to the sparkplugs. Rotate counter clockwise to remove the plugs and replace using the new sparkplugs. I strongly suggest an IRIDIUM spark plugs but if not available you'll be good at PLATINUM both single pin. Hope this helps and have a good one!

How to change the spark plugs


you need a spark plug socket usually a 5/8 and a ratchet with an extension (might not need it) you might have to tilt your engine forward to get the back plugs(fwd) remove the boot(connected to top of sparkplug) ONE AT A TIME replace the plug and plug wire if you are replacing the wires RECOMENDED trace them one at a time and replace it, plug it onto the spark plug, then on to the next one, MAKE SURE YOU DONT REMOVE MORE THEN ONE BOOT AT A TIME, OR SPARKPLUG AT A TIME. take it one at a time so you dont mess the firing order up.

Spark plugs


on top center of the engine. You would have to remove the intake hose. There is 6 COPs or Coil over plugs mounted on top of the sparkplugs. Remove those and the sparkplugs are accessable. Hopefully this helps

02 ZX2 runnig poor after spark plug replacement


Solution seems a little miraculous (although I believe in miracles).
I ohmed out each sparkplug wire finding them all good.
I wiped off the little debry that had collected around each seal of both the sparkplug and distributor ends (remember, I keep this engine clean and there was no noticable fluids or dirt before or during this problem).
I then replaced the same plug wires and viola, all is good!

My only thought is that maybe when putting the plug caps down in the sparkplug wells that maybe one or more found their way beside a plug inside of over and on the plug, but I did not take any wires off to verify this.
