all videos should be made like this one, short and straight to the point..thanks..

[truquerop]

I have a somewhat similar trick to check injector pulse...I have an old piece of tubing with a bolt at the end of it. Touch the bolt to the injector and put your ear at the other end of tubing and the sound is amplified...

Hey Thanks!! I learned how to fix cars back before fuel injection, so I did not know that fuel injectors made a clicking noise like that. I used the screw driver trick to find noises like clicking valve lifters, bad generator bearings, and so on.

05 magnum PO301 just solved it with this. Heard my injector cut off for a .5 second per 5 minutes causing my misfire intermittently. Even that .5 second will throw and keep your CEL on, this merely tests for injector complete failure. Good stuff.

[BoostedFilms]

Yea i was surprised it turned out so well too! That is basically what you should hear resonating off of the screwdriver handle.

This is great, gonna try this right now

[ethanphaethon]

That is really cool, I can't say I would've ever thought of that. Keep it up.

[SonnyWolfSmiles]

Awesome method, I've been doing this for years . Thanks for creating this video to help others .

[sashanesterov]

I read about this, but never believed, nor I've seen demo . Thank You! 

[RacinRob]

Wow, the audio on injectors turned out great.

[snakeeyes]

This rocks! You just saved me a lot of hassle. My car started misfiring yesterday so I replaced the plugs and wires, but that didn't fix it. I took it to a shop I trusted, but they told me it was the spark plugs and wires. WTF?! So after looking for possible causes of a misfire, I found this video and sure enough I can't hear the clicking on the cylinder that is misfiring.

You can also pull the wire connected to the injector. If the injector is faulty there will be no change in vehicle idle. If that injector is not there will be a noticeable difference in idle.

[nathersharif]

that's really clever way to diagnose the injectors

[jimmckee]

Excellent...!! Quick and easy. Thank

[baldwin]

this is a great way to tell if the injector is firing or not a good way to diagnose the problem for sure. if it is not getting a pulse signal from the ecm, the injector will not fire.

[chrisgonzales]

or you could use a mechanic's stethoscope and it helps in many other areas of the vehicle! pretty cheap too.

[rwbishop]

Also known in some parts as a 'poor man's stethoscope'. Incidentally, most any hard linear material works just as well as a screwdriver, even a cut off piece of wood broomstick.

Other applications are picking out bad bearings, listening to relays cycle on/off in noisy environments, and so on. Keep it in the back of your mind.

Don't laugh, this method often works better than most (but not all) commercial stethoscopes and other 'listening' type diagnostic instruments.

grea! thank you! i was about to buy an expensive tester but this actually worked!

[calamitycabss]
