On this video I take a look at a 2016 GMC Canyon that was towed in as a crank, no begin. Did not take lengthy to see it had a gas …

Good ole Govt Motors….LOL
I like that you pointed out how GM is accidentally on purpose locating components on the underside rear ends of their vehicles to corrode and wear out prematurely—talk about planned obsolescence.
Love your diagnosis skills man. You're like a walking oracle 👍
Mr O, I really enjoy your videos very informative but recently something is going on with your mouth exclamation exclamation it is very annoying to the point I can't even concentrate on what you're talkin about all I can hear is your lips and tongue sticking and sucking and slurping what's the deal?
Why don't they fill those modules with potting? Even if the board is only conformally coated, eventually the housing will corrode and leak. If the whole thing is full of potting then water will have a much harder time making it to the board. This seems like the only way to be sure a module located under the vehicle will not succumb to water ingress. It probably makes the module marginally more expensive and would really cut into the factory replacement module sales.
Potting works for electronics in explosive gas atmospheres (to prevent the explosive gas from making it to the electronics potentially allowing ignition – see: IEC 60079-18), it would work for water too.
Good explanation on your diag. Thanks

One thing is certain, cars are engineered to be guaranteed for the warranty period. So should we(independent shops) really dislike enginerds?
The big takeaway from this video for me was that module was only $100 from the dealer. There aren’t many modules with more than 3 wires poking out of them at that price point.
I have a 2006 ford f150 54 v8 will not turn over plug in code reader nothing key on or off all fuse a relay good could it be the pcm i
Made to fail😕
Good job
Been with you since the beginning, glad to see you didn't pull a ETCG and start flashing the $$$, swag, and your keeping it the same. I did buy that flashlight you got there, I am impressed with it. Thanks. If you can ever recommend a under the hood 6' light, let me know.
Ford did the same thing fuel pump drive was mounted to the axle and it corroded, new one came with rubber legs to prevent contact between aluminum to steel.
Thanks Teach! That was a good one. Imagine you had a big ego and instead of using service data you just decided to try to figure shit out? And you were half your current age? Yeah that's about 90% of the young guys in the business I've come across. I hope some of them watch your excellent lessons and expand their horizons. Oogga Dugga.
I like to watch while waiting on tickets to come in. I have learned so much between you and Rainman.
Throw that Chevrolet away
Where has Ford put their FPCM at on their trucks the last decade and a half or so? 🤣🤣
ChaChing!
My 09 Colorado has already had 2 of the modules replaced that sit above the spare tire for getting full of water and corrosion. Def stopped doing any drive thru car washes for sure
Take cover the air raid sirens was going off.
If you can do it any one with your experience and knowledge and skills can do it , and that is a
fact. That's why vehicle owners bring there broken pos vehicles to you. Just sayin.
Why don't drivers have under carriage cleaners for their autos up north? I don't even live in the rust belt and I bought one for my truck and it works so good, you should see all the dirt and grime it gets rid of.

Another quick, accurate SMA diagnosis by the great Eric! This owner should be happy his truck was towed there instead of a GMC dealer, where he could've been soaked for a bad ECM or other!
Eric, You are a great example as a troubleshooter, mechanic and human being. Thank you for taking care of people like you do, especially your family and cat.
I must tell you this video made me laugh so much taking me back to days in Michigan I worked with rain/snow/salt dripping the whole time the vehicle was in my bay. After that laugh, Ziebart took me out laughing. Then we had some completely sprayed with oil on everything visible from the bottom of the vehicle looking up. The only thing you missed on this was leaking valve cover gasket leaks, power steering leaks, rear main leaks, Trans. leaks and oil pan leaks. Get out of it while your young Son. 🫠
Remember Eric, there's a big difference between, "Short power to ground" (or vice versa) and, "Test power to ground"!
Is that a Gulf hat?
Been awhile
Think about it ENGINEER …. IDIOT 😏 Lol – love watching you diagnose the problems – then tell it like it is – HONEST 👍👍✌️✌️✌️
How is asphalt undercoating worse than thick paint on the underside?
Great Job ,like your sharing
Your video have helped me on my own vehicle good content
WOOOOOOT…..found one from 30 days ago….gaonna watch and enjoy !!!
When the repair is finished you should use a current clamp to see how much current the control circuit draws when activated. This is interesting because based on what you find you could make your own resistive test load that would be representative of the module input to use as a dummy load in the future instead of the filament bulb. So, the determined resistive dummy load in combination with the DMM on DC volts is a much better way to test.
The fuel pump control module housing is made out of cast Aluminum which is directly bolted to the vehicle steel body in the presence of salt water forming essentially a sacrificial anode out of the fuel pump body aluminum housing. Through galvanic corrosion this will essentially corrode (dissolve) the aluminum housing which is less noble than the steel. The lesson learned here if you are an automotive OEM is no wiring harnesses or modules underneath the vehicle. I know you have to have some wiring to the transmission which is usually underneath the vehicle. However, the fuel pump module and its wiring harness should be located within the vehicle and not underneath it to avoid any salt spray. Obviously, you would need a connection at the tank. But you would try and minimize any harness or connectors subject to salt spray.
i always carried fpm for our F-150's on my shop truck because they rotted out so often! Mounted right by the spare tire!
Not only do I believe you, I would trust you to hold my wallet.
Just commenting so the comments don't stay at triple 6.
Wow 6ish years old and it won't start with low miles. Pisses me off.
Umm. All the smart,( not so much) companies follow what each other do. Ford does it the same thing. So Ford Bashers and Chevy Bashers can get bent. They are both junk nowadays. It is very sad that this is a throw away world. When our resources are gone, we all will wish we built it to last. I won't be here to see it, but our offspring will. We are screwing future generations out of a descent life. I'm thinking anyway.
Gas Direct Injection is Junk as Well. Absolute garbage. Bring back Multi-Port-Injection.
Come on Mrs. O, couldn't you just tell Eric it's roadkill just once when he asks what's for lunch while filming his genius skills?????? Ha Ha!
I would put globs of silicone on the back of that module before reinstalling, just to be safe. It may or may not work but is worth the try. That salt problem is atrocious up there!
Eric, you should get a DMM with a low z mode. That's specifically to eliminate those 'ghost voltage' issues. There's other ways around it of course but they make meters specifically to eliminate that issue.
Nice diag. I was wondering why you didn't take the spare tire out and now I know. Great idea to have a spare tire you can't use and a control module that loads up with salt and fails. You will be busy for a long time.
