The day before I left Potosi, I tried to start my motorcycle to refuel.
Once again, the engine wouldn’t start.
This is a similar symptom to the last time, but this time it’s a little different
The cells are rotating
I checked the battery voltage and it’s about 12.5V, so there’s no problem
So it’s not a battery failure
Next I tried to check the spark plugs, but I didn’t have any attachments and couldn’t check the condition of the plugs, so I went to buy plugs and tools
I was asked, “There are cheap Chinese plugs (Bs.50, about 7 USD) and slightly more expensive Brazilian plugs (Bs.70, about 10 USD), which one would you like?” So I bought both just to be sure
When I got back and checked them, they were both made in China

I also bought an attachment to turn the plug.
It cost Bs.40, about 5.6 USD.

I tried replacing the plugs, but that didn’t change anything.
Next, I thought that maybe the air was the problem because Potosi is at a high altitude, so I removed the air cleaner and tried turning the starter, but that didn’t change anything.
Well, this motorcycle isn’t a carburetor, it’s an injection-injection vehicle.
So I had no choice but to find a nearby repair shop and have them take a look.
The mechanic told me that he thought the fuel pump was breaking down, so gasoline wasn’t being supplied properly.

Even if I wanted to replace the fuel pump, I was told that there were no parts in Potosi and I would have to look for them in larger cities like La Paz or Santa Cruz.

I can buy it from Mercado Libre in the neighboring country, but I looked for a company that can deliver internationally, but there was no company in Bolivia.
The motorcycle is now working for now.
The fee for the diagnosis was Bs. 300, about 42 USD.
