O how i wish all this training for free was around when i was younger, so many questions would have been answered. I hope all these young guys realize how truly fortunate they are for this training at the fingertips for free. I lost count of how much money i have thru the years in training material..Great videos and thank you for all of them.
I love this quick tip format. It’s like drinking from a fire hose...blink once and you are done for. Keep up the great work!
SD The king of diagnostics
Scanner Danner the diagnostic God of our time! This dude goes above and beyond and spreads the knowledge for the better of the people. Love the whole collection of videos. Sometimes I just watch even tho I already know what he is teaching 😂 can't help it
@@josephs9268 definitely addictive, i have a friend who's eager to get in this field and i told him to buy the book, join SD website to watch his classes so he did, last time i met him he was raving about SD way of teaching!! He's buying his first scope now
@@Airman.. precisely, I am also purchasing my own scope. I've learned a lot from scanner danner, almost like I was personally in the classroom. My diagnostics game would be nothing without these videos 😂
Thanks Paul. These small bits are so helpful and digestible. Even an honest shop might have said a person needs a new head gasket with this indicator. This was truly amazing.
Thanks again for everything you do! I spend more time having to prove myself right to customers than I'd like to, using links from your videos to help reverse the damage these horrible parts changers that call themselves mechanics have brought to our industry.
I’m slowly and slowly getting better at my diagnostic skills. There still a lot of learn tho. I just recently diagnosed and fixed a 2017 Honda Civic Ex with no power no start. I was nervous 😬. Love this channel and as well other channels like Ivan or Eric. Thank you 🙏!!
Awesome. Great job. Great courage to move into the unknown and come out victorious.
Kevin Culver thank you. It was a nervous wreck. I read wiring diagram and studied the system before I came. I was nervous because of my lack of experience. It’s actually my cousin’s car.
Great video as usual Paul it's always a good day when there is a new scannerdanner video thanks for everything
Paul these quick yo the point videos are a nice addition to your regular videos and your premium videos. Thanks for sharing Artie 👍👍👍
Thank you Arthur!
So much information in such a short time. Perfection in the edit, dialed that lesson with perfection. Well done Team Danner.
Thank you my friend!
One of my favorite videos, thanks for throwing it back 🎥💨
That info is waaaayyy beyond my skills, but I liked the video, and I liked the shouting over the engine noise, keeps things real!
Scanner Danner, you are the man!!! Always learning something from you. Thanks for making me a better tech.
It's always good to go through these you always relearn something.
I just installed 4 new fuel injectors in a 2.0 liter Honda (255,000 miles) and immediately had the long crank, stumble and then idled fine. I thought that one of the new Standard Motor Products injectors (from RockAuto) was leaking into the manifold but I'm going to try this same test (engine didn't have this issue with the Honda injectors I just pulled).
Thanks for posting this video, Paul!
Thank you so much brother scanner danner.
I appreciate your dedication on put on This videos sharing you knowledge helping us to fix our vehicles by ourselves.
Actually had this happen on a 1993 Ford Ranger with a group fire injector setup. No joke liquid gas coming out of the tailpipe.
Great vid.this is why I like older automobiles without computers lol.great diagnostics
I had a harness melted like that in my 2002 chrysler town and country. It was a mess. I wound up repairing the harness. One wire at a time I cut them respliced an soldered them in butt splices and shank glue-filled heat shrink over the splices. Everything was fine until I finally got rid of the car. Chrysler made that harness too long and suspended it above the exhaust manifold. When that fixture fails the harness drops down to touch or almost touch the manifold and the insulation melts, the wires short together and all kinds of misfires occur on one or multiple cylinders.
Keep up the good work scannerdanner.
Same thing on 2003 grand caravan, fried the wires together. But computer PCM shut down for safety. Was tough to diagnose. Had to take intake manifold off and replaced the harness. Quite a challenge.
My dodge journey is doing this exact thing. With the smoke, long crank, rough idle. Thank you for this video. Now I know exactly what is going on.
Always learning something new.
Very good qick tip for diagnosis. Paul perfect Job, thanks.
I am working on this today. 1996 chevy S-10, 2.2L, 144K, Base, MT-2wd, 13in rims ! Customer described exact symptoms in video.
Massive white smoke & gas smell-after he worked on inectors himself. Unfortunately young man drove it till it died, towed-in.
About 3-4 qts fuel mixed with oil in crank case.
Watched the original years ago. Thanks for sharing... Cheers.
Hey Paul. I love your videos long or short. Maybe longer, I dont know. I love em all. 😆
Another great job, thanks so much Paul
Danner choppin this up like “ready work”
Thanks man.i just put back on the road my 2003 tdci ford focus with one injector refurbished.engine runs ok small difficulties at start with white exshaust smoke.i am electrician.i believe this video can help
Beautiful! Thank you for sharing so very much.
How is it that Scanner Danner only has 260k subs?
Great stuff, thanks! Also watched the original video, as it was only 2 minutes longer 🤣
haha I know, I wrestled with even making this one a quick tip video because of that, but this version is much better and it is actually more like 3 minutes shorter (intro and outro added, with a clip at the beginning). The other thing is there is a lot of clean up that gets done along the way. Thank you so much for the comment!
Auto diagnostic stuff is not a content that would fit everyone. And that's the beauty of this and similiar channels. They're just not for everybody.
All the good stuff is pay per view
He got one more today. ;)
To go at the number of 100.000.000 subs ,you have to pass the number of 260k subs.....🤣🤣
excellent info never seen this happen before
I'm an engineer but not on cars however this is how I fault find ,,no guessing,,this dude is one of best car techs i have ever seen on youtube,,super smart guy ! Instant subscriber !!
Thank you!
Excellent video!
Dude this is awesome I love this
GREAT JOB THAT WAS AWESOME
Thank you for this video buddy, lifesaver
Thanks, I had that problem before Thanks again
Thanks buddy that was helpful for me
You save my life, everyone said white smoke is steam or oil, thank you so much!!❤️
Make sure you change your oil after you fix your injector
I have this on a 3.0 SIDI in my shop right now. White smoke and everything..no fault codes just white smoke pouring out the exhaust.
I think I like these more, watching them a second time around, ha ha.
Me too because we've learned how to edit 😂
Great video thanks!
Awesome thank u mr danner👍
Good tests
thanks scanner Danner ur AWESOME in my book always. cheeeeeers
Thanks for sharing SD👍
You explained very complicated process in simple words😉
Thanks Caleb👍
Stay Safe Guy's❤
Great video thanks
stuck open injector on a honda civic 2001 4 cylinder. Caused almost hydrolock and super poor running barely able to get to side of the road before it completely shut off. Glad I didn't keep cranking.
In my company, that stuck open (leaking) injector often occur in GMC Acadia and Traverse.
Good information
Excellent dignoses.
I like this style a lot better.
Ones agen live master 👍you are fantastic teacher this is vary short video but it means a lot
You got the biggest thumbs up
A good diagnosis with a not too difficult fix. Continuity test would also be safe.
Continuity would not be useful in testing the computer driver 😉
You’re the man.
Thank you for the video. Now how do I replace the harness? Mine looks exactly the same. I have searched and cannot find anything. What is the name of the harness?
Very helpful.....
Should’ve been an easy harness to get from the junkyard. Great video.
They’re all melted or melting mate
Usually, returning faults on a cor/known issue is not wort getting used parts for.
At work I am mainly on german cars so i change door locks all the time on Audis since there is a common fault. And 2 times ive been told to put on a used part and I've told that it wont last but the customer tought it was too expensive.
1 mont later and the same issue but now a new part instead, we got paid twice of course since it was customers call but they wanted to save a few bucks and ended up paying 150% instead of 100% 😅
Thank u for explaining..
But if we have a problem with ecu ecm pcm how to find the control diagrams of injactors puls for all ecus. Ecms.. Pcms
Best regards
Awesome!
I've actually seen this 1st hand. Although, my situation was one further, the melted harness did cook the computer AS I pulled it into my bay. Fixed the harness then couldn't figure out what the hell, b/c car wouldn't start......
Hey Scanner Danner, I own 3 vans with this engine. Even though none of mine have had this problem yet, where would you get a new FI harness ?? Does the dealer still sell them or do you have to go aftermarket ??? If the only choice is aftermarket, what would you recommend ??? I would be very wary if the only choice available was Dorman !!!
What are then names of those back probing pins. Keep meaning to order some, but can't recall what they are called?
my guy surfing while talking about cars LOL
Can same happen if ya see the spark from plug on one cylinder arkin out and onto the manifold from under the boot? So what fuel is being sprayed into it is not being fired off?!
I just learned something
Light gray smoke or white smoke sometimes close color but a little different.
Smell like maple syrup? Or fuel?
Had rhis happen on a 2011 enclave , motor was recently replaced and owner thought head gasket blew.
Hey I have 2015 f250 6.2 gas truck that out of the blue started to blow white smoke on a start up. It clears up and seems to idle smoothly but under load it starts blowing smoke and missing. Then cleans up again in time. The laptop (buddy’s son) shows power down on #4 and #7 we checked for broken valve springs (common 6.2 issue) and checked cold compression (with an actual gauge) both #4 & #7 were in 180 psi while compared to #2 175 psi and #6 195 psi so within 10% but it does seem to consume oil. But the fact of the 6.2 consuming oil does not surprise my buddy son being (young ford tech). He is kind of stumped on what’s going on with the motor. Can I send you a video on the smoke? Thanks Jeff
I can just hear the engineers now. Where should we locate this harness, well how about where there is no excessive heat, right next to the exhaust it is then, lol. Hey Scanner Danner a quick question. Why does that not blow the injector fuse? I had a Saturn S-series once that was shorted on the ground (switched) side, blowing the injector fuse. Seems weird with all those wires touching that there is no blown fuses.
I never new this
Thank you for this Video. I think I may have found an answer to my problem. Tons of smoke out of V8 Savana GMC. Engine runs smooth , no over heating . NO codes after I fixed misfire in Cyl 2 by cleaning a very dirty stuck "closed" injector. However, the smoke remains . I believe one of my injectors are malfunctioning , giving too much gas . I will replace all 8 injectors tomorrow and see. However, I do hear all injectors ticking strong (with screw driver test). Very puzzling :(
If it's running smooth, you definitely do not have an injector stuck open
Позавчера на машине с открытой форсункой блок поменял, пробитый транзистор на форсунку оказался и не закрывал ее и тоже в пятом цилиндре
My Lt1 is missing and running rich also it smokes sometimes. I'm trying to figure out what's going on? Lt1 is a pain.
I imagine that was a great scent behind it LOL
you can unplug the harness at the ECM and check for short to ground, no feedback issue possible, with some caveat!!
this is what I did! The feedback is still possible even with the entire ECM disconnected because of the way the supply side of the ASD circuit is wired
I had that a while ago on an Acura Integra, the pcm was shorted and kept all 4 open! The engine was literally filled with fuel
Crazy! I've seen one driver do this but not all of them
I love ❤️
Nasty smelling exhaust!
Danner, can you recommend a place for professional technicians to discuss live diagnostics? Every now and then we all need a little guidance when hunting for a diagnostic path. Any ideas?
My forum on my website! We have over 17k members across the globe and it is free to join. www.scannerdanner.com
Great video. Dont really understand how the test light could back feed and find a ground with the engine off? Can anyone help explain, thanks
I put a note in the video on this ASD circuit. The key is understanding that this ASD relay circuit is NOT powered up with just the key on, as it also runs the fuel pump, so your test light can find a ground through the dead supply circuit and then thru the pump motor to ground
@@ScannerDanner thanks for the reply, these shortened videos are gold!! Keep them coming!
I once saw that melted wires on a jeep.
Might be having this issue in a OBS chevy 5.7 vortec. Too bad the stupid injectors and things are buried in the intake! I might have to tear it out anyway as it may be the intake gasket.
I have some tests you can do on this system that I show in this video th-cam.com/video/09_wQ9yQ85A/w-d-xo.html
th-cam.com/video/dAAFM3zlJME/w-d-xo.html
It involves a fuel pressure gauge and bleed down testing.
we have a renualt np200 its starts but smels petrol and smoke white
I have an important question, i had a stuck open injector and i fixed it, before raw gas would drip out of the exhaust tip and misfire, i fixed it but it still smokes white smoke but only when i rev it, its white, do u think the excess gas on the catalytic converter is still burning off
How long have you ran it since the fix? Did you change the oil too? You need to if you didn't. And yes, the exhaust will smoke for awhile after
I know I'm late but I replaced a stuck open injector and fuel pressure regulator on a 454 vortex so it's all good now but it's still blowing white smoke but doesn't smell like pungent gas anymore. Does this take a while to clear out because it's left over in the exhaust system or should I be looking for something else that's wrong. Another interesting thing is I pulled the fuel pump relay and the vehicle continued to run for another 10 minutes until I shut it off.
Oil psi switch will bypass the fp relay on these. That part is normal. And yes, it will take some time for the fuel to burn off. Also CHANGE YOUR OIL!!
That harness was so destroyed😱
Hey brother I got a 2007 dodge charger and my ground on the starter relay doesn't stay on when I turn the car over the starter clicks one time while trying to start battery is good starter to I ran a ground to the relay and it starts up every time any suggestions?
Without looking at a diagram I can't offer advice
But we can help on my forum

ahh so how would i apply this to a ob1 system..and no scanner...or just replace all injectors...93 3.9 magnum
also what the diff colors of injectors...at salvage yard see blue..white black and yellow.on magnum engines
Different flow rates most likely? Not sure
I have a 1996 GMC Yukon with a 5.7 and I get white smoke when vehicle is first started on cold days like below 45 degrees and below. Could this be a fuel injector problem also ? I have replaced upgraded my central port injection to multi port fuel injection about 5 years ago. It takes a long time to stop blowing white smoke compared to other cars on cold days only. Great video very informative.
What does the white smoke smell like? This one, there was no mistake about it. It was as if you stuck your head into a container of gasoline
I believe I smelled fuel. Right now today the fuel trim is like a -3 LTFT and close to 0 STFT.
Definitely not the same issue, not with that clean of trim numbers warm
Thanks for the reply SD I’ll keep an eye on it until it gets cold again. I will probably check for a leaking intake gasket when it’s cold again. 👍😎
So my car is smoking a lot and I'm hoping that this is why and not the worst case scenario of a blown head gasket.
A stuck open fuel injector would make me think that I should smell gas. Should I or not necessarily or not at all?
Absolutely positivity no mistaking a stuck open injector! Complete raw fuel smell. If your guessing you may smell fuel, it's not the injector
How long will it take for the white smoke to clear up i dont want it to catch fire
It won't unless you have an exhaust leak. Not enough oxygen in the exhaust
How can you tell if it’s a head gasket or a stucj injector
Are you losing coolant? Is it overheating? A stuck injector will not cause these things. Also if it is a stuck injector, it smells like you dunked your head into a bucket of gasoline, that is how strong the gas smell is. If you have to question whether it is a gas smell or not, then it would not be an injector.
👍
I think I have this problem. Will see tomorrow if it sprays.
Amazed there were not more fault codes looking at the mess the harness was in.
It was because none of them were truly touching each other until I opened it up. Only the #5 injector control wire was touching a ground or ground wire in that loom
Got a 2008 2.3 fusion I’ve been workin on , replaced the plugs, injectors, pcv valve and head gasket on it, still has a high idle at start and a rough idle once warmed up. No coolant loss or leaks, doesn’t seem to be misfiring, just lots of white smoke 💨, any ideas what it could be? I’m thinking the cylinder head is cracked at this point.
White smoke isn't good and neither is the rough idle when warm. An injector that is spraying constantly can give you white smoke but you'd also have a long crank time and a single cylinder misfire as well as fuel in the oil.
Get a block tester kit (chemical) and test for the presence of CO2 in the cooling system
@@ScannerDanner thank you my friend !! Will try this out and see what happens
Mine is thin light white smoke smells like gas and said open circuit and I also have valve cover gasket leaking
Now what if you couldn’t find a harness. Fix all the wiring?
yes sir
