KRAZ 255B Cold Start Attempt After 20 Years – Engine Won’t Fire Up?

Published at : 12 Dec 2025

I would like to thank the owner Jožo for making this project possible. Respect
In this video, we attempt to start the KRAZ 255B after 20 years of being left untouched. The engine cranks, but unfortunately, it doesn't fire up. After some investigation, we discovered that the fuel pump had seized, preventing the engine from starting. Watch as we try to troubleshoot and understand what went wrong. This legendary truck is a true beast, and despite the setbacks, we’re determined to get it running again. Stay tuned for future updates as we plan to fix the issues and attempt another start!
