How To Test Spark Plugs AND/OR Coils On Any Car (INCLUDING RECESSED SPARK PLUGS)

[@1099firebug]

Great no nonsense video!! Start to the point! Great job!!

[@davidgruen7423]

I just want to point out today I encountered a tricky problem. So I have a car with V6 engine that has multiple misfire just after having replaced new plugs, new spark plugs. I found out cylinder number six has problems by using the risky unplugging method, and I swapped that coil with number five cylinder, and did the unplug test on those two cylinders, now the number five cylinder has no change, so now I know the plug that was on cylinder number six which is now on cylinder number five is bad. And weird thing happens as I use spark tester tool, when I check just the bad ignition coil itself, the tester actually flashes! However when I include the spark plug in the tester it won’t, on either number five or six cylinder, so the spark plugs are not at fault on these two cylinders. My understanding is this bad ignition coil is just weak, that it can pass the spark test by itself, but it won’t function under normal operating conditions. Gotta say the ignition system is always tricky! Hope my experience helps!

[@mrweisu]

Why is the last test a test for spark plugs? The light blinks but it only means the ignition coil/wire is good. I am confused. Thanks

[@philldavies7940]

because its now being grounded via the spark plug. So there must be a good electrical path from the coil, via the ignition pack, via the spark plug to ground for the light to flash. There's a couple of means to spoof that, but it would mean a very broken spark plug (eg the spark plug insulation has broken down , or the spark plug gap is 0),

[@CharlesGwinn-ep9pb]

Best video ive seen yet. I assume your second test( testing the coil secondary resistance by connecting it to ground) also verifies that the primary resistance ( between the male tabs at the top of the coil are up to snuff) It might also be good to use a multimeter to verify that both primary and secondary resistances are within the oem specified ranges for a particular vehicle. I don't know that the mere presence of a spark would mean these resistances are necessarily within range or not

[@JB-yc5gc]

Thank you for taking it step by step...its Great Video! When testing the spark plugs does it matter how bright the light is on the tool Aid?

[@turnbowtime]

This is the best video I’ve seen so far on this. I have been looking for awhile too. Thanks a lot man!

[@mcphelan1]

Great video. Why did you choose the light adapter bosch 2? is that the adapter for a honda accord?

[@noconsentgiven]

You said you had a misfire was it the spark plugs? You didnt say in the video.

[@jsollien127]

Today's mechanic must have so many tools. Great video, thanks!

[@jamesdavie7782]

Thank you for being straight to the point. I Can't Stand the guys who ramble.

[@E_ina_G]

Very informative and appreciate the link definitely going to be adding this for diagnostics currently dealing with a possible bad connector on a new harness or a bad new sensor

[@ochicoloto3524]

Nice! You said it had a misfire. You tested all 3 components and all passed. So what was the issue?

[@martythomas7703]

Is this the same process for coil on packs as well

[@concretejunglesnakes3389]

Will the test work if the car doesn't start? Good video but I believe you should do the same test on a non starting car, that's the main reason someone would won't this kit

[@CharlesGwinn-ep9pb]

If the car doesn't start or even attempt (ie firing but not quite starting) chances are either NONE of the coils are getting spark OR you have a fuel delivery problem. To eliminate the fuel problem pull the air breather inlet pipe(from the throttle body or as close to it as convenientally possible) squirt a few squits of starter fluid into the pipe towards the throttle body and crank it. Have someone ready with a towel just in case a small fire erupts(lol). If it starts momentarily then engine is probably getting fuel although doing a fuel pressure check at the fuel rail Schrader valve would confirm this.And it's highly unlikely that all injectors would suddenly stop working. So if you have fuel then you need to consult the manual to trouble shoot the ignition system for your car/truck.

[@billywhittington2490]

I missed the link to this kit he has

[@maherahmed1977]

Hello, thanks for the video, can I use it on my Corolla 2006 as far as you know for the wiring

[@reyzapata9375]

Question.?. Can I use this tool on my 1999 Mercedes Benz with Coil Packs with 2 plug wires per cylinder’s.????.

[@barryalan4069]

Straight and to the point Great Job.

[@horacefratsnatch9341]

It appears the coil harness has 3 prongs and the Noid light has 2. How do you know which side to connect it?

[@ACommenterOnYouTube]

Good question that he didnt mention

[@MUHAMMADKHAN-pe7ez]

there are 3/4 wires in the harness connector. which 2 be connected with noid light and how to identify them????? you are silent on it. will you clarify it????

[@kurtiscal3msetccdwell618]

It seems to me that the last test is not capable of testing the spark plug as all your seeing is the coil pack firing and not the spark plug electrode firing or how it is firing.

[@atari7001]

It’s a lot harder for the spark to jump through a spark plug due to the compressed gasses in the cylinder acting as a powerful insulator. If plug voltage is too low, you won’t get a spark and the light won’t illuminate. This can indicate a bad coil.

[@cocinandolamecanica]

It’s a great tool kit man! But you are missing the wave form test. Greetings!

[@fahedmahases723]

@@cocinandolamecanicawhat is the wave test?

[@cocinandolamecanica]

@@fahedmahases723 you must use the scope to do that. in this case I can try connecting my oscilloscope clamp directly on the wire between the coil and the spark plug to capture the waveform of the secondary circuit. Greetings 👋🏻

[@Jbajapaca]

Hi, I have a problem with my Mini Cooper s r56 not start. The mini was on taking it out of the garage when it suddenly turned off. The first Scanner have these codes: 2781 2775 2D52 *2DCA* 275F 272F I changed 4 spark plugs, 4 coils, the Camshaft Position Sensor and a new battery. But it did not turn on, now it is giving these codes: 005E31 009314 *00A0B4* 00932D 009CB5 I deleted them and it only gives me this code: ( A0B4 ) The mini starter good but not start. I try the new battery and it says it's ok, but when I test the battery with the terminals mounted on the Mini Cooper it says it's bad I don’t now why. I also reset the new battery in the mini system with the scanner but nothing. ( A0B4 )

[@hernanzetino5287]

Will this work on Toyota for the wire harness?

[@christiaantober2461]

You said the coil was good, but the light was flashing quite erratically. Would you not expect a more rhythmic flashing for a good coil?

[@georgehuerta1990]

What’s the name of that test kit I would definitely like to have one of those I’d like a little tool that you use to test the wiring before you test the coils and plugs

How do you know which one of the bulbs works for your vehicle because I put the Bosch 2 bulb in my 2011 Tacoma 6 cylinder & it ain't lighting up

Will this work on classic cars like a 68 mustang with Hei distributor

[@kybjump7899]

Quick question, if they were in bad condition they woudnt have light up right?

[@voisindo]

or the light would be very very dim

[@khalidalaa8078]

can i test them with test screwdriver (the screwdriver with lamp and a clamp on the other end )

When you hooked everything back up it still won't run?

The spark plug one didn’t make Sense to me because Wouldn’t the Light Turn on even if the spark plug is bad,

[@ACommenterOnYouTube]

No it wont light because the spark plug completes the path and if that plug is bad and does not complete the path for that current flow, the light wont come on.
