- Electrical short , GM Buick LeSabre, Pontiac, Chevy, Cadillac etc. solve electrical issues due to a BAD GROUND , Ignition Failure no Spark, Cam sensor , crank sensor.
Cigarette lighter not working. Fuses good.
--------------------
What you need to know:
The Fuse block screws hold it down tightly to a grounded plate underneath. If corrosion is under there, or the bolts holding down become loose over time, ...you’ll have AMAZING intermittent electrical problems/issues and eventually they will become so bad you’ll say BAD WORDS!!! Issues stemming from this problem can be near IMPOSSIBLE to diagnose.... Fuses will test GOOD but in fact there will be no power where you need it to go. All other grounds might be cleaned and working, but your problem will remain.
You’ll even start doing CRAZY things... like replacing parts you know aren’t bad... just so you’ll have something to tell your friends.
Eventually, your dignity will be left in shreds and you’ll still have no solution. Your friends will leave you... your spirit ancestors will be crying out to you with the answer... listen to them! And if they can’t fix cars... good thing you found this RUclips video.
THIS IS NOT ROCKET SCIENCE. ANYONE CAN TIGHTEN THESE.
note: some comments are saying their bolts are completely gone... keep this in mind:
there is a gap and flat contact of metal between the top and bottom halves of these GM fuse blocks just like the on the Ignition modules. If yours have been loose a long time and/or you live is a wet nasty place, there is probably a ton of dirt and bad stuff in between the top and bottom halves on the flat electrical contact area. Be sure to inspect and clean anything that could interfere with the electrical ground. I'm not a real mechanic but I believe there is even a dielectric grease that should go in between the 2 metal halves to protect from that happening. good luck
PS. As pointed out in the comments.. .many GM cars have more than one fuse block... those cars with battery under the back seat, also have +Pos and -Neg connections and fuse boxes there... if they are corroded, and/or not grounding well = same problem.
I just it bought a 1999 Super charged Buick regal GS had it two days ,on the second day I took it to work. Then pulled it in the drive way. Drove like a dream. Next morning NO START ... NOTHING! RAN THE BATTERY DEAD TRYING TO START IT PERIODICALLY THRU THE DAY .... CHECKED RELAYS AND FUSES, READY TO START TESTING FEUL PRESSURE. AND SPARK. THOUGHT I'D LOOK AT U-TUBE FOR A TIP OR TWO .IM SO VERY VERY VERY GRATEFUL I DID ....
I WATCHED YOUR POST AND I KNEW RIGHT THEN YOU WERE 100% RIGHT BECAUSE I HAD NO SCREWS IN MY FUSE BOX .WHEN I TIGHTENED THE LAST SCREW TURNED THE IGNITION TO HEAR MY CAR PURRRR .
ITS PEOPLE LIKE YOU
THAT MAKE A DIFFERENCE IN THIS WORLD. THANK YOU SO MUCH.
This videos 6 years old and it’s still saving lives like mine today very much appreciated 💙
Man your a lifesaver no joke I truly appreciate this video thank you so much for putting it out, my car has been out of commission for over 4 months now since July and I've tried everything. I have the same model and year as yours and my screws were loose, tightened them my car started right up no more problems so far truly a godsend bless you sir!
🎉🎉🎉 BROOOOO!! I feel so bad for you! 4 months would be the worst!! I’m super glad you left a comment. Makes me happy 😃
Dude, our LeSabre wouldn't crank at all...my regional tire/repair shop ran codes and said they couldn't help and that I needed to take the issue to a dealer for new PCM or ECM and flashing...they estimated $1,000 for dealer service. This video solved that problem!!! Muchas gracias!!!
Gm fuse boxes have a way of coming loose ty them bolts tight
I was having a similar problem. Sometimes my car wouldn't start but was turning over, and sometimes when I turned the key to start it didn't do anything for a second or two. After
watching this I checked my fuse box, and it was barely on the fender! Wow. I tightened the 3 bolts down and Problem solved! It has caused a lot of other electrical problems over the years. Thanks a million! I was changing all kinds of parts and nothing worked until now!!!!!!
I have to say after much pulling out hair trying to figure out my issue with my 2002 Buick Lesabre. Your tip and hint based on the tightening down the bolts of the fuse box was amazing and saved me so much time and money. I thank you very much! It worked immediately after doing that and has started every time!
I have a 2006 Buick Lucerne V6. Needed a new battery changed it & then would not crank. All accessories working but when I engaged the ignition switch console went dead. Checked all fuses & relays in both fuse boxes, all good. Checked starter by jump 30 to 87 terminals on crank relay terminals, it is good. Finally found this video so checked the three bolts, tightened them and it cranked right up!!! Thank you!!!! Have not found any other video or resolution informing about this. Grateful!
Hey I don’t have those 3 bolts on my Pontiac what size are they so I can buy some new ones ?
Thanks for not giving up and sharing with us the fruits of your labors.
Ahhhhhhh... I change everything and boom a one minute fix ughhh man you are a life saver
i was looking forward to a long and painful weekend working on my 04 lesabre. tried this and it started up first try. thanks king 👑
I spent two days off and on trying to figure out what the problem was. I had loosen the three small bolts to remove the cover and never would have thought that to be the problem. If I thanked you 400 times it would not be enough. ( Bolts didn't even need loosened to remove cover) THANKS AGAIN
Wowwwww man thank you so much 🙏🙏 tried this on my 07 Grand Prix and it starts even better than before 🤯 amazing video
I've been racking my brain on a 2004 Century. Cleaned all points of contact which made a huge difference in the lighting, but no crank. I'll do cart wheels all the way home WHEN this solved my problem ! GRACIAS AMIGO !
Lifesaver. Mine had no bolts in it at all. The moment i wiggled it around it cranked right up! Finding hardware today
Men bro after watching your video I did what you said and tighten those 3 bolts up and my cigarette lighter and auxiliary works now thank you bro you rock men
Girlfriend's 04 LeSabre has been having intermittent crank/no start issues and I'm definitely going to be checking this out this weekend. Her lighter doesn't work so maybe that's a good sign that this is an issue. Super frustrating because whenever I go to diagnose it, it works again. Thanks for posting this!
Just did it. Lighter worked. Amazing
Thank you so much I was having the same problem was tired of it when I watched this I went right out side s😉and tried this and it started right up 🙏🏻🙏🏻🙏🏻
I LOVE IT!!! We are defeating defeat!
I have never run into this issue. Been doing this for 50 years. Been running my own Shop since 1988. I got a 98 Bonneville in shop now putting in a fuel pump. Bet yo a== I'm going to crank down on these bolts while it's in here for precautionary measure.
Thank Bud.
You are a gentleman and a scholar!!!! The epitome of an erudite!! This salvage me! SOO MUCH LUCRE I WAS ON THE WAY TO DOLING OUT FUNDS MAN! Gratitudes!!
Mane I just went through that same problem replaced all kind of shit just like u ended up fixing a crank seal oil leak and it was weird that it finally ran but now this makes since cause I was lookin for a ground that I know was the problem but didn’t know those bolts was a main ground and u the first person ever to say it was that and it fixed that common problem thanks 🙏🏾 for this
Just did this with my allure. I have 4 bolts on this one and they were all loose! Still get delayed starts, but my cig plugins work now! Thanks for sharing
Woooow! I just tried to tighten the screws for this same problem only to realize all the screws were missing. On my way now to track down the screws. I'll keep u posted on the results.
I am trying to fix my own Buick Regal right now, but they are all missing on my car too. It looks like they are not used on my car. I popped the back panel off and there is nothing attached to the threaded holes.
@@iturbo5733 same here. It ended up being the ground wire on the starter. It has to be good and tight. Started right up.
@@iturbo5733any luck
WOW this tip save me time and money and a ball of confusion thank you my guy
I have a 96 Buick Riviera Supercharged same problem I can’t thank you enough only my fuse box is not grounded but the both grounds in the back seat one from the battery the other to the fuse boxes were super corroded thanks once again 🙌🏽
Thank you so much for sharing!!!! That was my problem as well. I had all dash lights but would not turn the engine over On a 2001 bonneville. Thank you once again!
Did it sound like it had no compression in the engine
My 2001 Bonneville won't start
Im going to check mine! I will be so happy I really hope this is my problem! I'm tired of trying to figure out!
I'm headed home to try this right now!!! thanks
This trick worked on 2006 buick lacrosse. Thanks for the great vid.
Amazing!!! I have an 08 Lacrosse, was having intermittent electrical issues, airbag light on etc. Tightened down these 4 bolts and the electrical issues disappeared, airbag light off! TY
I sure am grateful. All day yesterday and could find problem. Found your video today and I did it. I actually had loosen them thinking it would open fuse box. After it didn’t I pretty much didn’t worry about them afterwards especially when it quit cranking.
I'm going to go check this before I replace my crankshaft sensor today.
I've got a '92 Regal. After having a mechanic replace the steering column for me, as well as the ECU, a crank sensor, some control modules (all of this over a few years), and after having removed the factory stereo for aftermarket install, then reinstalling original stereo for periods of time and going back to aftermarket units a handful of times:
I suddenly started having no power to the radio circuit, my dash lights stopped working 99% of the time, but they cut back in here and there, my tach started acting up and pinning itself to the bottom (it once even wiggled itself over the stopper and got stuck under there for a few days), my headlights would cut out on me on very hot summer nights, then come back to life after the engine sat and cooled off a little.
I'm going through all of the grounds, cleaning and reseating. I can't find any real info on all 3800TPI ground points for a '92 Limited, especially for interior.
But I can guarantee that many of these issues ARE related to corroded contact points in some way.
I've had several older rusty GMs with bouncy fuel gauges, turning signals speeding up and slowing down with engine RPM. I've had a rust-bucket Venture that suddenly stopped charging its battery altogether, and I could never find the specific problem. I had a Fiero that would only start cold, but would no-start crank while hot, I sold it to a dude who simply cleaned up the battery tray and it started on a 1/4 turn each time. I replaced the coils, wires, bought expensive-ass plugs, before learning that it was all because of one bad ground.
All that to say: GMs are exceptionally unforgiving for electrical resistance; sometimes a seemingly unrelated circuit screws with the one you're actually having an issue with.
It WILL screw with your head sometimes. Don't pull your hair out, don't dump your money into replacing major sensors and modules. Take a step back and try probing elsewhere, first.
(This is coming from a guy who wasted thousands of dollars through several cars, often over just one actual bolt. Learn from my mistakes, my friends!)
Dude I'm soooo trying that. We change the fuel pump starter fukn everything..I'll let u know
Update
love how simple that was
I hope it worked for you too
You sir, are a fine upstanding individual! After exhausting much financially, you gave me the reprieve I needed from the wrath of my loved one! Hah!
i hope it worked for you man! good luck!
Thanks buddy, I'm gonna try that right f*!#in now, changed the clacking harmonic balancer, ran for 10 minutes, nothing.... Just got done checking the wires and connectors for the cam and crank sensors, jack shit, no spark. Thanks.
Thanks .
I am having the same issue
Will check it in the a.m.
That was it, omg thank for the video
Ha ha ha, my frustration motivated me posting the video... and I’m mote and more glad that I did. Glad it worked.
For other readers you should know that many GM vehicles have more than one of these type fuse blocks in the vehicle. Look for others under back seat, on the right side, etc.
I love you bud. No homo but damn bro you saved my ass just now thanks man!
Thanks you just save me a ton of money and a headache
Im gonna try this. Ever since my original ICM went out, Ive been having it replaced due to stalling and ive replaced damn near everything that could be asides the crankshaft sensor. Something has to be cause it to go out early. Some of your description such as slight hesitation before start up is one on times when its replaced and overheating. Fingers crossed.
I have a 2004 Impala 3.8 that cranks but won't start, even with starting fluid being sprayed in the intake. I have already replaced plugs, wires, coil packs, injectors, O2 sensors and the crank position sensor. I wish I had seen this a few months ago! Now the car is in the shop and I can't even go try this... FML
I have the same car same problem. what ended up being the problem?
@@notgaybear5544 it was the ignition module. It's located under the coil packs
Wow dude we are gonna try this on my friends 2003 Buick century if this works...you effin rock.
Thanks bro. Been bashing my head on this one.... bing bang boom who knew
Hey man thanks for the video, this literally happened to me today and was able to fix the issue no problem
IT WORKED !!! Thanks thanks thanks 😊
Glad it worked for you. Thanks for letting me know. This video was like sending a message in a bottle. Had no idea if it would ever be found but was hoping it would at least help someone. And it did! Haha. My kids threw a 100,000 views party cuz their minds were blown, and we read the comments. Hope to do it again if 200,000 ever watch this. Go forth and prosper!
This is the best video ever
Just checked my Buick regal's fuse box and all 3 screws are gone...how did it ever even go..? Lol
Dude thats awesome. I'm having the exact same issue. Will let you know how it goes. Thanks for the tip!
Did it work?
Did it fix your problem
Thanks Guy. What a tip !!!!
Bro you are a legend 🙏🏼🙏🏼
Bless you Fr 🤙
Haha you’re welcome. I felt the same way when my car finally started again too!
Lmao this is awesome, this sounds like exactly what my friends car has been doing for a year, so random and the shop replaced the starter but it didn't fix the problem, we will be going over to try this. I hope it's this
Hahaha, some cars have more than one fuse block so check them all. Under the rear seat? Etc. Good luck
I owe you a steak dinner and a cold beer.
ty I left my car in a parking lot tonight with what seemed like a dead battery, but I brought the battery home with me and it had 12.5v so I think I have a bad ground. I will check on this when I go back to it!
Thanks bro . Lol after I changed fuel filter and then fuel pump. Wish I would have seen this video 8 hours sooner. But really! Thanks for the video!
Mine was doing everything except receiving fuel. Even started for a second when I used starter fluid.
You MIGHT have to replace MAF sensor. First, unplug it and see if car starts. If it does, then plug back in. If it kills the engine. It was MY MAF and it now works!
Having just the cigarette lighter problem, will tighten things down tomorrow and see if this works.
Dude I changed altanator and moved box. Out if way and you just saved me another 75 bucks.. Im hoping anyways.
I went and look at one a guy had for sale ($800) with 194k. Would crank but no start. He said he thought it was something in the steering column
The 3 bolts are fastening the main power wire harness connectors to the bottom of the fuse/relay panel. At least on the LeSabres I've delt with. On some models like the Park Ave, the fasteners are tightened from the bottom. I can see problems arising if these bolts come loose.
I have the same motor and issues, I already check those three bolts and are tight and won’t start, the fuel pump is two weeks old and it was running today really smooth and I was driving it and the motor stop running
change the relays by switching them with the same noting which was changed,they also bounce and lose contact because they,re cheap.
LMAO with the lighter.
Thank you ur video is amazing big help
My goodness, I cannot wait to try this when I get home. I have 2007 Buick allure with the 3.8 and I replaced everything you mentioned. fingers crossed.
Jonathan, Did it work?!
no, they were loose though! Tightened them up and nothing unfortunately... However, there was no compression on 4/6 cylinders which lead me to think either a busted timing chain or a busted camshaft. I'm popping open the timing cover this weekend.
@@jonathanandrews1407 Did you fix your Buick?
@@snutmeez I took apart the entire side half of the motor and popped the timing cover...it was the chain that snapped. In the process of putting the new set as we speak. I've always read that the 3.8s don't have timing issues, but I've seen a few series 3 motors on here with what literally sounded like the same issue. Weird.
@@jonathanandrews1407 Damnnnnnn.
I understand your effort,.. good job.
Throughout my life, I've seen four different cars with this same engine. Ford Mustang, Pontiac Bonneville, Chevrolet venture, and Chevrolet Silverado.
great job thanks for the video
I have a 97 grand prix with the same problem. Checked the fuze box and it doesn't have the bolts that's you show in the video. Does it supposed to have em?
Mine are missing those screws in the fuse block. Do you happen to know the thread size on those bolts?
*Update in case anyone needs to know those bolts are an M6-1.0 x 20mm for the fuse box. Thank you for sharing this video as i was definitely having electrical issues and no cigarette lighter i put new bolts in and my cigarette lighter works again and the electrical issues stopped. You are my hero!
Awesome thanks for the luck !!
I have a 1997 grand prix GT with 3800 v6. Anyone know ehat kind of wrench key or screwdriver to use to tighten my fuse box down? Torx Allen wrench and screwdriver dont work. Help? Mine is loose and has issues starting up as well. This could be the problem. Help!!!
Insane tip thank you
Hope this might be my issue. 02 Buick won’t start and only one of like 5 cigarettes lighters work. Has spark fuel compression
I’m having the same problem on my 97 Buick park avenue I’m going to check this out tomorrow and let y’all know if it worked
Did it work?
Friends 1998 3.8 olds 88 does not have that fuse box there or anything like it, hair is now turned white trying to figure it out...
Ok, I tried to perform this with my 98 Buick regal but I do not have those big screws. May have changed. What wrench did you use?
Same thing happening to me! 02 park ave no screws in the fuse box
@@rebholz6 do you guys know what size those screws are ? Mine are missing and I need to get new ones
For real?? If that doesn't fix it. Whats round 2. Coil packs and ignition control module
I think you just saved my ass! Thanks!!!
I just got so excited to try this. Tightened then a little but still have the crank but no start.
Me too got all excited. Tightened them down... and still no start. Wont even turn over. Cigarette lighter is working tho.
What screwdriver do I need ??? Because a regular one won’t work . What specific screwdriver I need
Thank you
Lol having the same sort of issue, looked at my fuse box and guess what? No bolts, I have no idea where they are but when I find them, they are going back in.
Majerr RP Swap THOMPSON what type of car I have a 96 camaro and can’t find them neither
I am thinking some do not have these bolts. I have read many comments saying they are missing the bolts, and I don't have the bolts in my 03 Park Avenue.
Mines had a antifreeze leak fixed that now it won't start fixed everything you just said if it this im kicking this car ive been pulling my hair out refusing to take it to a shop let me go tighten these bolts...
I have a different issue , 2002 Buick lesabre limited I turn the key but nothing comes on no sound maybe one click but nothing turns over I’ll try this trick rn but I think mines may be a starter issue
What did the car sound like before replacing all of those sensors?
Ok I think I’m having the same problem but my car will start only when I press on the gas. I’ve changed everything but fuel pump
I tried it and it works thanks so much for the advice but when I drove it about 2 miles to return the crankshaft sensor I left it running come out the store it wasn't running anymore but still on so I cut it off and tried to start it back up it was turn over but wasn't starting again ... Do you any other suggestions???
did you ever figure it out having same problems
Thanks so much man save a lot of money for me 👌
does anybody know the size of the bolts ?
I'm having the same issue
What if it cranks ounce? Not that drawn out crank?
I have a Buick lasabre 2001 just got it from shop I had to get break lines fixed and all I was having a no start situation....now I drove it home and I tried it this morning it cranks all lights come on but no ignition ( like the car completely shuts down.
2008 buick lacross 3.8 crank ,no start also,,,,codes 0030,0031, 0201-206,,0412 ,0413,0418,,where fuel control module?,,checking grounds
So I just looked at mine... I only have 1 bolt at the top of the cover it is missing 2 bolts in that fixed block
You probably just solved it bro! Make sure underneath is not corroded /oxidized and then tighten up your new bolts. 👍
No it didn't solve my problem. The box isnt grounding that side. My car runs for about 40 mins and dies. It kills all ignition and wont start until a few hours to next day. It has to be ecm
I have the same motor, mines a Buick regal, just died one day at idle,, started then died again ,, then crank crank crank wont start,.when i looked at my fuse box under the hood it looks a little different but its free floating like you can see three aluminum square nuts with threads inside, but no bolts anywhere other than one big wire bolted at rear of it any idea ? crank sensor? everything else in the car seems to work ok
Did you find the issue
@@-g.k.4389 the main coil control module under the coils,, but I went on to replace the cam sensor and crank sensor, they are cheap off ebay
Wow thank you
My fuse box has the three holes but doesn’t have the bolts….does anyone know the part number for the bolts?
Thank you so much I did not tie them down I was about to by all the same s!#t bro 😳🙏🙏👏👏
I'm having the same problem my 3 screws are missing does anyone know what size
