The Big White Bus Will Not Start (Post #624) September 18, 2023

Well, awesome. The Big White Bus won’t start.

I have fired it up once since I parked it in my newly constructed shoppe 5 years ago. I guess I should have expected there would be “issues”. But I wasn’t expecting the issue to be this one.

Mr. Fisher came over and we diagnosed the issue. We started with checking the power at the pump. As you may be aware, when you turn the key over it powers the pump briefly. So if you just “turn on the key” and go back there to check the voltage you won’t find any. That’s why it takes either some seriously creative use of a volt meter or you get one of the bestest friends to come over and turn the key for you. We had voltage all the way through the wiring harness.

We then confirmed we have spark from the ignition system. I pulled the number 1 plug and with a screwdriver I grounded it and watched for spark. You can buy a fancy spark tester, matter of fact I think I own one. I have no idea where it is though. Spark confirmed.

So we have two of the three things (Meatloaf would say that “ain’t bad”) to make the vehicle run. Air and Spark. Now why aren’t we getting fuel.

I pulled the gas line off at the regulator on the back side top of the engine and had Mr. Fisher crank the ignition. We should have had gas squirting out if it worked. It did not. This fit with me NOT hearing the pump run when the ignition was turned over.

The only thing left was to pull the fuel pump and do a visual inspection. What I found was not expected. I said, “Wow.” a lot in the video. There were several parts that were obviously degrading due to being submerged in petrol for so long. There was visible rust on the steel parts as well. Generally the pump was in a terrible state. I was not aware that petrol would do that to those parts. The only gas I ever put in my Classic is 100% real gas, unless I am in Texas where they only sell ethanol (at least the last time I was buying gas there). You would expect ethanol to eventually separate and turn to water. You can read all about that on the Road Guardians website.

I will be replacing the fuel pump and have ordered the part from Atlantic British. I found some that were cheaper on Amazon. But my skepticism and need to have it delivered before next October weighed heavily on my decision where to purchase. The pictures all looked like the pumps were manufactured in the same place. Same white plastic. Same blue plugs.

If you look on Amazon you’ll see the pumps look like the same ones. If I had unlimited funds or sponsorship, I’d buy one from everyone and do a side-by-side comparison.

All this “BUY IT NEW” has me thinking about what this would cost if we just fixed the pump. All you need to do is replace the pump in the collector can (that bottom part). I’ll do a post about that in the coming weeks.

So…do I drain the tank too? If the gasoline HAS turned to varnish I should probably put some treatment in there. I’m thinking I’m gonna add a silly amount of STP Fuel Injector cleaner in that tank. I can say, WHEN I get it running It will run for quite a while before I shut her down. I want to give the truck plenty of time to dislodge any crap in the fuel lines. I’m also guessing I’ll need to swap the fuel filter too.

If its not one thing, its another. It really, never ends.

Mr. Fisher also brought over his Viair Compressor. We spent some time looking at it and checking out all its features.

Thanks for reading and Happy Rovering.
