Thank you! Was having the same issue with the F350 here at work. I need to get a better diag tool, and access to electrical schematics. If not for your video, I'd still be banging my head against the wall! Now i need to decide whether to just run a wire, or actually go through the harness and find the open circuit...

Dude, you are my hero !!! Had the same issue and was trying to find the problem for nearly two months! Thanks a lot for such detailed video!

Great video, I was looking to fix my PATS system in my truck and came across this video. Very helpful for those having that problem. Mine is a no crank no start situation ill keep looking hopefully I find the reason why.

Just wanted to say this video was extremely helpful getting me on the right track to find the solution to this same issue with my 14 f250 6.2 gas. Mine had a stripped corroded wire on the bottom side of the fuse block that basically killed the power to the row of fuses behind the relay discussed in the video. I had enough room to cut it and repair it and the truck runs like it should now. Thanks for making such a detailed video!!!

I have a 2011 f450 and the brown with violet stripe wire was broke/ chafed about 6” out of the junction box. Thank you so much for putting out a decent tutorial on the diagnosis.

Hey buddy, how did you fix that? Thanks

This video helped me fix my '15 F250. Didn't have to dig nearly as much thankfully but found that the 12V constant to the starter relay was shot. As a "temp" fix I just soldered the two HOTS together on the starter relay and now everything works (for now). Figured it's relatively safe as the working HOT line was the one that has the 10A fuse so technically speaking they're both on a 10A fuse now. It is what it is but I'm happy to have a working truck again lol

I've ran into this many times on the both 6.7 and 6.2 engines. Also, the wire from bcm runs from the firewall on the a d along underneath the fan shroud up along side the head light support into a wiring support bracket. They also chafed on the backside on the support.

Hey, Great video. really helped me along with mine with the same no crank issue. My truck wasn't actually the ground control side of the relay but was the power supply side "jumper" to the relay under the fuse block. it has corroded from and also very melted ac compressor clutch feed wire from the next fuse over. #47 I believe. probally see a lot of this on older SD's thx again!!😊

😊 My 2012 f350 had the same problem and after watching your video I was able to isolate the problem to the relay. Removed relay and it failed test so I got a new relay and the truck works like new. I never would have even able to determine anything about which relay or even if it was a relay. I checked the voltage on the same fuses you talked about and found no power our of the relay. Thank you

You have amazing videos they help

First check the fuel pump reset switch located on the passenger side of the front seat by the right foot. 9 times out of 10 it's that switch.. It won't throw a code if that's the problem.

@@eddienavarro8126 inertia switch in a ford does nothing but cut fuel, it will cause a fast crank but no start condition. You probably have a faulty bcm. You can check the bulk head plug down by the drivers side lock panel. Check for corrosion at the pins usually spotted from the back of the connector. Also a fault tow haul at the end of your shifter can cause the engine to shut off.

Tell them to check the pins on the plugs that plug into the BCM (passenger side kick panel). The pin fitment can get loose and cause this problem.

Did the ground on fuse#48 that you rewired fix the blower motor fault as well?

I started my 2011 6.7 yesterday after work but forget to put the key in and press the brake, so it turned off ( happens usually) I tried to turn it on again but this time it didn't started, I could hear the diesel pump, I tried to junp it no didn't work, i get new batteries and installed them but it was the same, so I'm guessing its either the starter or maybe the pcm

Did you check to see what wire was actually broken?Was it the brown/violet wire?Im having the exact same issue ..no ground firing from bcm,no power from relay to starter..My brown/violet wire is not broken though

Man your Awesome

How did you go about getting the schematics of the truck??

I’m pretty sure that my truck has the same problem it’s a Ford F-250 2008 how can I fix it!!

Can you send me the link for the scanner you have and how much it costs??

This is my problem also but no ground on 85 and no power 86. Do you know where those wires run from the PDB? Do they go forward towards the front of the truck in that raceway or do they go back through firewall? I've heard that some of the pins in the wiring harnesses go bad too? I've been working on this darn truck for too long chasing the problem. Last night I finally found it and made jumper to 30 and 87 and bingo started right up but I want the permanent fix and also to see where the disconnect is to inspect other wires

I am having the exact same problem, but I cannot tell where in the Body Control Module (from the video) that you connected the jumper wire? I can't seem to figure out what relay was not passing a good ground and I don't have schematics. Any help would be appreciated. Thanks, If the Key is on, and I put 12V on the underhood fuse 52, The truck starts until it is unconnected.. but 49-56 show a ground not a voltage, and on the BCM, I have a whole row of fuses without a voltage. It all started when I replaced my Backup Camera (which was not working) and since fuse 49 gets no juice, that is still out, but now I can't even start my truck.

1 million dollar question. My truck tests identically like this on. Going to run a new wire from fuse box to bcm. Only question for you is that is the brown violet strip wire one run from fuse box to bcm or does it stop else where?

@prodieselrepair3218

Doesn't go anywhere else from what I can remember. Check your pin fitment for that violet wire on the plug that plugs on to the BCM. I had another one with this symptom and that's what the problem was. The pin in the plug was too loose and not making a connection when it's plugged in.

I was following along with your steps until you tested fuses with key on to tell you pcm relay was working. Mine isn’t showing power. Tested relay and seems to be ok. Ideas on where I should look? Seems those fuses are engine power but I’m getting no power with key on or off. Help please

@prodieselrepair3218

Жыл бұрын

The 6.2L is going to be a little bit different than this one. If you don't see power at the PCM relay like you should, then you have to find out why there's no power there. If there is power through the fuse you need to find out where you're loosing it.

Sucess! I figured it out by purchasing the same wiring diagrams you suggested. I wasn’t getting power past the PCM relay to the fuse row with 33 & 35 fuse. So I ended up dropping the fuse box and opening it up. What I found was 5 broken wires and two peanuts. Seems some rodent had found it’s way into the fuse box and chewed through the wires. I was able to strip and reconnect the wires and it fired right up. Glad you had the video or I wouldn’t have known where to start looking.

Not a bad video - how ever - The one thing that I would have also checked on is the grounds because just running a new wire and not balancing and fixing the ground - as Power flows from - to + not + to - You might be giving a fix that is only temporary where the fix might be a weak link and back feeding might happen because the system is out of balance, the Computer might detect that and fail internally. Grounding points are the first and should be always suspected in a vehicle like the one you worked on in a condition like that truck was in.

You are sort of correct. Yes the electrons do in fact actually travel from negative to positive. But does that matter? No it does not. We can design and engineer any DC elctrical componant with the idea that the flow is going to positve to negative and it will still work. There's no such thing as "balancing" or fixing one part of the circuit and not the other. In vehicles we have one (sometimes two) batteries with a positive and a ground. Everything has to start and return to that battery. There's 1000s of circuits that run of that one battery. So naturally you are going to have those cicuits, at some point, share positive and negative power.

Need this guy to look at my truck 😂
