is that they wake up one morning to find the Landcruiser doesn't want to fire. I'm fairly pedantic when it comes to accuracy in film and attention to detail and so I want a problem with the 13B-T that would stop it from firing. I'm thinking something that can't be fixed on the side of the road, perhaps something that requires parts? Parts that you wouldn't normally carry. And not something cliche'd like a flat battery.
That's simple... Failure to function with the fuel and air shut-off VSV because it's bolted to the side of the block where it gets too hot. The truck won't start unless the vac line is pulled off the actuator butterfly valve in the turbo pipe to bypass the VSV. The VSV isn't a common part one might have along. The quick fix was to remove the bolt that secures the VSV to the block and pull the VSV closer to the firewall with mechanic's wire. This kept it cool enough to function OK.
