In this video I bring you along as I have a look at a customers Ram 3500 with the big hemi that was dropped off with the money light on. I took a look at it to discover it was missing power to the fuel tank pressure sensor. Now it is a matter of determining if it is the PCM or broken wire.
-Enjoy!

Using hose to prevent abrasion is a great idea – highly recommended. I use it all the time and keep a bin of various sizes of old hoses I've removed from cars (free stuff – better still :).
QUICK TIP: Spiral cutting the hose with a utility knife and then wrapping it around the harness has the following advantages:
A. It works to transition 'Ys' in the harness. And two spiral cut hoses can be interwoven to cover the junction of branches in a harness.
B. A spiral cut hose won't retain water like a split hose might if the cut was on the upper side.
C. A spiral cut hose stays in place on tight bends without tape or zip ties.
D. The hose doesn't need to be the 'right size'. A hose with an ID smaller than the OD of the harness can still work.
E. And spiral cut hoses can be used to hold a harness together temporarily while troubleshooting, testing, or rewiring. When done, you can be taping up the harness while unwinding the spiral, saving the need for an extra hand. (Keep it around for the next time)
Hey Eric I saw in video 4.06 min broken chassis wire 905A ground wire maybe related the other wires. Because i’ve ground wire issues
I wish the bottom on my truck was covered with “crud†looks like excellent rust proofing
Little by little I get better at reading wire diagrams thanks to this blog. thank you sir
Buy a tone generator to trace down wires and shorts.
Having driven through a puddle of liquid cow poo and suffered the smell-o-vision for an hour afterwards, the fact that he did the whole job "dry" was a matter of self-preservation!
WELL THAT WAS A SHITTY JOB
One wire wizard does it again.
23:24 found the Easter egg scotty kilmer ?😂
Wow wiring under prop. shaft.what a engineering. 😅😅😅😅😅😅😅
You can find worm from mud.😂😂😂😂😂😂
I think you may be an alien. You get the broken wire finding ability from all your ancestors who were working on their space ships.
Again simply amazing. You have a way of finding things I’ve spent days trying to find. Very good.
It would feel like scanning all the cables for rubbing problems would be a good thing, but as many mechanics would tell you, if it's not broken, then leave it alone.
Old man glasses? I put on a weak pair for general reading and a strong set for the critical view of circuit board repair. Bad boards can look fine but show damage under magnification.
Lucky guess I would say experience is the word
Eric, I won't need to do 99.9% of the repairs you do in my lifetime, but you have me ready in case I do. Just a weekend backyard Hondo mechanic enjoying the best, funniest Youtube mechanic out there!
🤔👌
Come on man 😂.
It's just grass and water Mr.OðŸ‘
Good job he didn't go to the dealer, he might have ended up with a new fuel tank, purge valves and a new PCM before they gave up and presented the customer with a $5000 bill!
Thank a farmer, free fix
Clean as a baby's behind
Nice job! Thank you for supporting us as farmers.
Eric, I really enjoy your videos. I have learned so much and even did the brakes on my Nissan Murano for the first time ever after watching your content. Thanks very much. An interesting fact for you since you enjoy the word CRUD with significant enthusiasm. It is actually an acronym that stands for Chalk River Unidentified Deposit. It relates to some extremely hard deposits found in systems of early nuclear reactors. They were first researched at Chalk River Nuclear Laboratories, part of Atomic Energy of Canada Limited in Chalk River, Ontario. Go, CRUD!! All my best to you and your family.
looked like enjoyed chewing on gum and poop dust taking down brace lol
Supernatural gift.
Finding broke wires counts.
hope he washes his hands before lunch
Yep ..I'm watching and learning some of those troubleshooting skills
Its called skill Eric Finding broken wires is a skill….apparently a good skill to have especially when working on a farm truck with " crud" on it.
“He’s hammerin on that Hemi…†– you have the best one liners.
Great troubleshooting again.
ðŸ‘ðŸ»ðŸ‘ðŸ»ðŸ‘ðŸ»
Cool, thanks for telling me the plan…. yea, I'm Stan.
TIL i have the same EDC gerber.
