The Yukon decided it wanted attention on the way into town today.
It started hesitating, bucking, and acting like it was running on hopes, dreams, and leftover fuel vapors.

I hooked up the ZEUS+ while limping down the road and noticed the EVAP system was commanding the vent valve open, but the fuel tank pressure sensor was showing around -15 inH₂O.

That's a problem, because when the vent valve is open, tank pressure should be hanging out around 0 inH₂O, not trying to recreate the vacuum of outer space.

Fuel trims were climbing positive too, which told me the engine was getting less fuel than it wanted. The poor fuel pump was working overtime and getting nowhere.

I made it to O'Reilly's to dump some used oil, but instead of leaving, I turned their parking lot into an unpaid diagnostic bay.

I started with the vent valve since they're common failures. It was open and flowing fine. Next, I disconnected the purge line and watched the tank pressure immediately return to atmosphere. Interesting...

Then, for scientific purposes (and because I apparently enjoy suffering), I blew into the canister vent line. I nearly collapsed a lung trying to move any air through it.
The charcoal canister was plugged up tighter than a shower drain on Kashyyyk after a Wookiee family reunion.

What's happening is the purge valve is doing exactly what it's supposed to do. The problem is the vent side of the canister is completely clogged. So every time the purge valve opens, the engine starts trying to suck fuel vapors out of the tank, but no fresh air can get back in to replace them. The result is enough vacuum in the fuel tank to make a Capri Sun jealous.

Eventually the fuel pump has to fight that vacuum just to move fuel, and it starts losing the battle. The engine goes lean, fuel trims skyrocket, and the Yukon starts driving like it's offended that I own it.

Therapist: "What do you do when a customer blows up your phone and says you're not a Christian and you didn't do what you said you did?"

Me: "Spend an hour figuring out how to download body cam footage and send it to them?"

Therapist : "I mean. . . "

Happy Father's Day from Be Blessed Mobile D&R!

Father's Day is a bittersweet day for me.

I have two children who want nothing to do with me because of the man I used to be. I love them dearly, and I miss them every single day. There isn't a Father's Day that goes by that I don't think about them and pray for them.

One thing I've learned is that when we truly surrender our lives to Christ, He can make us into a completely different person. The old man dies, and a new man is born. The mistakes of our past don't disappear, and sometimes the consequences remain, but God's grace can transform even the hardest heart and give us a new direction.

Those two beautiful little girls I once knew are now grown. While that part of my story still hurts, God has blessed me four times over with children He has entrusted me to raise today. I don't take that responsibility lightly.

Whether you're a new father, an old father, a good father, or a father who knows you've made mistakes, there is always something to learn from our Heavenly Father. None of us have arrived. We all have room to grow, more patience to develop, more wisdom to gain, and more love to show.

As fathers, we're called not only to provide for our children, but to guide them, encourage them, and point them toward Christ through our words and actions.

"And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord." — Ephesians 6:4

Today, I'm thankful for the children God has placed in my life, thankful for the grace He's shown me, and thankful that He isn't finished working on me yet.

Happy Father's Day to all the dads out there. May God bless you, strengthen you, and help you become the father your children need you to be.

— James

Another interesting diagnostic on this Honda Ridgeline today.

The customer had a red brake warning light that stayed on constantly. The ABS/VSA module was reporting that the parking brake was applied, so the first step was verifying the parking brake switch and circuit operation.

Using a multimeter and scan tool data, I verified the parking brake switch was functioning correctly and the circuit had proper continuity with the brake both applied and released. Since the switch checked out, I pulled up the Honda wiring diagrams and continued tracing the system.

According to Honda's wiring information, the red brake warning light can also be commanded on by the brake fluid level switch. The brake fluid level in the master cylinder was full from a previous master cylinder replacement, so I moved on to testing the level sensor itself.

The fluid level switch is built into the reservoir cap. Continuity testing showed the switch itself was capable of operating correctly, but the float inside the reservoir had failed. Even with the reservoir completely full, the float was sinking to the bottom and falsely reporting a low brake fluid condition.

To verify the diagnosis, I manually held the float in the correct position and the brake warning light immediately turned off.

A faulty brake fluid level float was causing the vehicle to think the brake fluid was low, which kept the red brake warning light illuminated even though the braking system was full and functioning properly.

New reservoir cap/level switch assembly has been ordered.

I guess it's Honda Day today. 😂

Two Hondas diagnosed, two estimates sent out, and enough Honda wiring diagrams to last me a week.

At this rate I'm expecting the next call to start with, "Hi, I have a Honda..." 🤣🔧

Today I discovered that the Yukon and I have something in common...

We both gain weight way too easily. 🤣

I was driving down the highway when the Yukon started shaking like it had just chugged three energy drinks and made some poor life choices.
Being the professional mechanic that I am, I immediately started thinking:

🤔 Bad tire? 🤔 Lost wheel weight? 🤔 Bent rim? 🤔 U-joint? 🤔 Is the 4L60E finally filing for retirement?

After some investigating, I found the real problem.
A giant blob of hot road tar had attached itself to the wheel and was riding along for free.

Apparently the Yukon picked up a few extra pounds and decided to let me know about it.
The good news is unlike my weight loss plan, the Yukon's only required a scraper and about five minutes of effort.

Now if anybody knows how to scrape unwanted pounds off the rest of us that easily, let me know.

Got this '87 R10 back up and running today!

The truck had been fighting a fuel delivery issue. The tank selector switch wasn't doing its job, fuel wasn't making it to the TBI, and the old Chevy wasn't exactly eager to start.

Instead of throwing parts at it and hoping for the best, we followed the wiring from end to end and found several poor connections in the fuel tank switching circuit. After repairing the wiring and verifying proper operation, both fuel tanks are now switching correctly and delivering fuel like they should. The truck now starts and runs off either tank with the selector switch functioning properly.

While I was there, RC had another concern with the electric cooling fans.

Previously, the fans would only come on when the engine coolant temperature switch grounded the relay circuit. That works, but it means you have to wait for the engine to get hot before the fans decide to wake up from their nap.

To improve cooling performance without spending money on additional controllers or fan systems, I modified the wiring so the A/C compressor circuit now triggers a secondary relay. That relay provides a ground signal to activate the main fan relays whenever the A/C is turned on.

In plain English: when RC turns on the A/C, the fans come on immediately instead of waiting for the engine temperature to climb. The cab cools down faster, the condenser gets better airflow, and we accomplished it without buying a bunch of extra parts.

Old trucks are a lot like treasure hunts. Sometimes the problem isn't a bad part at all—it's just a 39-year-old wire hiding in the shadows waiting to ruin your day.

Another old Chevy back on the road where it belongs!
