In this video I have a look at a 2016 GMC Canyon that was towed in as a crank, no start. Didn't take long to see it had a fuel delivery issue. Low and behold the salt is the cause of this no start. The fuel pump control module got a little crusty we'll say. P12A6 is the code we're going after.

hi sir, I am from Libya, located in North Africa, and a follower of your RU-vid channel. My main profession is a pharmacist. I run my own pharmacy to sell medicines in a small town called Jado. Car repair is my favorite hobby in my free time. That is why I follow car maintenance RU-vid sites. I would like to I express to you my great admiration for the way you work and for the order, cleanliness and perseverance with which you run your own workshop, which I consider the standard standard for the workshop that I dream of owning one day.. my great greetings to you and my wishes for continued success, progress in your work, and happiness for you and your family...

Glen from Australia here, you know what Eric?- you are a god damn kindhearted good-hearted gentleman, really the service you do and the manner in the way you deliver that with all the tongue in cheek anecdotes and humor is both refreshing and highly educational. As a backyard DIY grease monkey, I feel it when you start something up for the first time even though you feel you put every bolt back where it belonged and put the chain against all those marks - there is always that doubt isn't there? Eric, your a legend plain and simple for taking the time to share your pain and exploration into depths the cars owners dont want to. Good on you Eric - good karma to you always.

Eric, if I could find a competent and honest mechanic like you where I live I wouldn’t be a DIYer. What limits me is not having access to Service Data. Even with 8 vehicles of all different makes and models I still can’t seem to justify it. Keep up the excellent vids. I love it when I can tell myself “Here’s your problem lady!” 🤣

@FliesLikeABrick Год назад

Pretty much all the manufacturers have something like 3-day online access to their entire service data library for a reasonable price, I do that when needed for our newer vehicles (2013 prius) . For the older ones (2000 civic, 95 Ranger) , I buy the oem books used on eBay which is even better

Techs are incentivized to swap parts, not produce root cause diagnostics. 80% of the time it works fine, 10% of the time the parts cannon is fired (lots of labor and parts sold) and 10% of the time, they are forced to escalate to another tech and involve someone with Eric's skillset.

@chevboy4.813 Год назад

Ford had similar problems on their trucks. The new FPCM came with retrofit plastic spacers to install between the module and mounting surface to let water and moisture to drain to prevent trapping it behind the module. Of course the module was also mounted vertically, so that helps!

Back in the 1970s I was introduced to low impedance voltage testers. The brand name was Wiggy, witch is now synonymous with solenoid voltage tester from many brands. I have an Ideal brand. Works great for voltages from 90 to 600 ac/dc. Today I use a Fluke DMM that has dual impedance testing. 20M ohm and 3.5K ohm. Works great. Fluke has 3 models with this feature. The 114, 116 and the 117. I have the 116 witch has features like temperature probe, micro amp scale for measurements of flame sensor current and min/max recording witch I use to troubleshoot signals that last 1/5 of a second. Well worth the money and have never had a problem with it. I guess I should add for those new to troubleshooting, this will greatly reduce ghost voltages.

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. 🫠

Hey Eric, I had a 1978 International Scout II that was Ziebarted. My inner rear Quarter Panels rotted away. I used zip ties and mechanic's bailing wire to keep the outer Quarter panels from flapping. It was my understanding that to not void the warranty an annual "Inspection" had to be done near the anniversary of the procedure to maintain the warranty. The "Inspection" was to do the process again totally. The "Inspection" clause was in the fine print of the contract and most people didn't have it done. It also applied to the original purchaser only. I got my Scout in 1980 with 24,000 miles on the odometer. I kept it for 9 1/2 years and finally junked it. I enjoy all of your videos and await the next one.

@jimmyaber5920 Год назад

International hauled bodies in white across town plant to plant. They were not dipped or rustproofed. You live in Arizona and never leave your ranch and your scout or IH pickup would rot through.

@harrykrouse3999 Год назад

Back in the late 80s, my brother-in-law bought a 1979 scout from the original owner ,who was a lifelong friend of his stepfather. The original owner had used it as a plow truck, and it actually still had the snow plow on it. It was a rust bucket when he bought it, and he attempted to do a restoration on it and put it back on the road. He started to take it apart and then lost interest in it. It sat on the farm for another 10 years, and when they tried to haul it to the junk yard, I believe the Frame broke in half. It was one of the most rusted vehicles I had ever seen in Maryland.

Good job Eric! Testing the control side is a little more labor to prove the faulty module. Looks like your also checking wire/connector integrity, corrosion and fitment. Your giving the customer their moneys worth.

@christopherfranz1547 Год назад

The fuel pump driver module on my southern salt-free 2006 F-150 was rotted and the metal part of the case was actually cracked in half and deformed. I happened to notice it when I was installing some trailer wiring so I snuck a new one on there before it actually failed. It turns out that Ford decided to put the bare aluminum case of the module right against the steel frame of the truck. The aluminum against steel causes "galvanic corrosion". Some of the aftermarket ones come with stand-offs that address the Al+Steel contact issue, so I went that route ($40) rather than spending $220 on an OEM part that comes flawed from the Ford dealership.
