2011 GM Truck No Start Again...Comeback U0109 

Dude, you just earned a subscriber, here I was thinking it was a fuel pump, I got the same code that everyone does use 0109 sure enough I pulled fuse 21 and it literally crumbled. I put a brand new fuse in and it fired right up,absolutely amazing

Thank you so much! We replaced the fuel pump and then the control module, and nothing. Your video showed me that not only is there a fuel pump fuse (20), but 21 is the fuel system control module fuse, and mine was blown. Never though to check past the actual pump fuse.

I had a no start today and had to be towed home. I got a U0190 code. I watched your video and went to check the fuse 21 under the hood and sure enough it wouldn't come out, i ended up breaking it up and pulling the pieces out. After i put a new 25 amp fuse and it start perfect. Thank you so much. Saved me hundreds in parts and programming. I can now put this truck back to work tomorrow.

Men I appreciate this video help me my truck avalanche 2010 was broke for like 2 months and thanks to you,seeing that you pull fuse out it work for me, I change fuel pump and fuel control module and nothing, until I pull fuses out and it work, thank you God bless you and your fam

I am glad that you show your work in real time, as we all get tricked into missing the easy stuff like a bad fuse.

I want to say thank you for your video. It solves my problem with my 2009 Chevy Silverado. I clean my fuel injectors and put everything back together. I only pulled the fuel pump fuse(think fuse 20). Somehow fuse 21(the same one in your video) was missing. I think my roommates were playing a joke on me or something. All I know is I never touch that fuse and it was missing. Once I swiped it out, it started right up.

Man…I think I have the same issue on my 2012. Finding this video might have saved me huge… more to come

Got a 2010 Yukon in today, cranks but no start, u0109 code, watched your video and went straight to fuse 21, BINGO!!! corroded and had a huge voltage drop across it. I bypassed the fuse box fuse and installed an inline fuse holder, super THANK YOU!!!, you turned that nightmare into a 25 min job

Don’t feel bad, you did all the proper checks with the load test on the powers. Always say that doesn’t happen laying on the couch either fixing something or getting beat up on a diagnosis. Good find.

Lmao thanks alot for posting the video... I bought a 2011 4.8 l with 153xxx, that was sitting for over a yr .. would run when you feed her the gas but that it... went and bought a fuse and then and checked the fuses.. there was the corroded 25 and a 15 changed them both thing started right up and runs perfect best 1250 I ever spent

Great observation on the fuse diagram being incorrect! That as the nugget I was looking for..

You’re the man thanks for the video, saving the day for people. Huge props 👍👍👍

I'm sure that customer is more then happy you found the root cause problems , I would be more then happy with your work .

this was the EXACT problem I had after the same fixes..... Good ole fuse 21 was corroded. Wish this video was around back then 5 years ago !!

You're the man!!!! Exactly my problem bud thanks a ton, I had ordered the fscm for almost 200 and the fuse was the issue so don't need it!

It’s not always easy!!!! You did the correct diag..

I have to thank you very much I had the same problem crank no start. Pulled the fuse out one leg was missing jammed in another fuse and on the way I went. Thank you again for posting!!

thank you so much for this video my 08 escalade had these same issues and this fuse ended up being junk and now it’s fixed 💕

Same problem for me it ended up being fuse 21 appreciate it man

I will be dang! My 2013 Tahoe started the same thing. Wouldnt start and occasionally stutter. First time it did this it started after a few minutes. Drove it and went to Advance. The worker got his personal tester and found thar code. I didnt replace anything. Just happened this morning. Started up again after a few minutes. I figure it cools off and will then work. I get home and pull that fuse. Sure enough, the fuse is half burned but not blown. There is no corrosion otherwise. Ill be doing s thorough check though. Thanks for this.

HI Phil. I had the truck down for a day with a crank, no start situation. 2012 Yukon. Didn't hear the fuel pump cut in with key so pretty much knew is was a fuel issue. I have a basic code reader and it said FPCM not communicating....too easy. My buddy is a GM tech, has been for years. He was going to come look at it this am. Anyway.....I keep watching your video and see your run into the fuse box, the mislabeling, and corroded fuse etc....I had the identical issue. Changed the fuse and back on the road. My fuse looked just like the one you pulled. I had spent quite a bit of time fooling with that issue and if it wasn't for your video I'd likely have changed things out as you did initially. Took me hours looking at videos before I found the guru (you) who figured it out. Subsequently, I removed every fuse and sprayed fluid film down each and every port in that fuse box. I undercoat my Yukon XL twice a year and spray up under the fuse box as I knew they had issues with corrosion. I figure this corrosion started right on top of the panel because the rest looked OK. Running down the hwy in winter and reality is that that fuse box isn't sealed. GM needs to do a better job. Thanks for the video.

GREAT video. Thank you for sharing with us.

Thanks. my fuel system fuse F21 was blown. My fuse directory shows a relay in the fuel pump location and a 20 amp fuse in F20 like your example. thanks for the help!

Merci sa regler notre problème 🤘🏼

So we have similar problem codes p0230 and U0190 with a 2013 silverado 5.3 replaced fpcm, fp relay, fuel pump, and would always start up fine when it was cooler and overcast but as soon at the sun was shining and heating up it would not start. Did fuel pump command through scanner and test says short to voltage. Also the car drains the battery randomly

we have a saying in our shop did you KISS it? Keep It Simple Stupid K.I.S.S now the main question, do you give the customer his money back for the shops mistake??? still good video, its how you respond to your mess-up that keeps customers coming back, smart customers understand human error

just started running into the same issue, changed the fuel pump, then the fuel control module and it wouldn't let me reprogram it, turns out its not powered. feeling super silly wasting money on a fuel pump control module but it is what it is at least I'm not paying labour at a shop... hopefully this fuse box is all it is new fuse fixed it temporarily but problem kept getting worse. i think a weak battery doesn't help either.

Thanks for the good bad and ugly. Even great mechs aren't perfect.

Thank You for this informative video Sir.

Thanks you help me a lot with this video

I have a 2010 suburban with the 5.3 vortec and I've checked fuses 4, 5, 12, 21, and 56 with a test light and put a fuse and relay in the same spots that were missing in the video. I also installed a Pre programmed Fuel sending module under the vehicle and installed a new fuel pump and still nothing. I also jumped the wiring harness going to the FCSM and the pump came on. I'm lost. ECM? BCM?🤷🏽‍♂️🤷🏽‍♂️🤷🏽‍♂️🤦🏽‍♂️

Thank you 🙏

Hoping someone can help. I had this happen to me. I checked the same fuse after watching this video. Sure enough mine was blown. Now with the key off, not even in the ignition, I put a new fuse in, and it immediately blew. As soon as the fuse touched the fuse box prongs. Anyone know where I should start?

Ok this what my neighbor done..he recently buoght a 2011 gmc kingcab truck, the guy he got it from was rear ended and therefore took bed off but it's set for bout 4 months abd guy told him he drove it awhile after reck then parked it then wouldn't fire up. So..my friend got brand new feul pump, it's cranking but no start. He checked feul pump by hooking to battery to see if pump works and it did. So..he's checked brain box, all fuses, still nothing but..I don't know if he checked pump relay switch to reset it. But this where we are..

I have a 2009 Silverado and it was running fine but then died on me. Before I did anything I always check fuses but the same thing on my truck, the relay and fuse are not where it says it is suppose to be. Would you be able to tell me where else to look or what to do next? I dont hear the fuel pump kicking on so I assume it is the module but im not sure how else to confirm.

is the fusebox non repairable? have you tried opening it?

Thank you 🎉😂

Hello, I received the code U0109-00, but the car is running normally. I reprogrammed it, but it did not work, and I noticed an increase in gasoline consumption. Note that I disconnected the ABS socket due to a malfunction in it. Is it related to the code?

You just saved my ass

I just checked my fuses because I’m having some hard starts in morings my 12 Silverado cranks but sputters for a couple seconds but I noticed the fuel pump fuse and relay did not have anything in them , found that odd ???

Man that is crazy. It’s sucks when we get burnt. I’m interested in known how the customer took the news and how you handled the situation if 3 repairs for the same complaint?

How much was the new fuse box from the dealership? Great video

How do you remove the top portion of the fuse block? Thanks

Hey hi mister Phillip I have a 2013 Ford f450 6.7with this code P20C1 I already replaced the redundant heater two times and still the check engine light on, and still it telling me the same. Can you help me with that please

Was exactly my problem

Did that fix the problem?

My damn box label is wrong also

What if the headlight actually fried it 😂. :(

hope you put a new fuse box in they are junk

It's the fuse box itself. I am literally dealing with the same issue currently.
