I'll ask Sierra Fox about it because the original has the same outdated layout.

I have made a version that functions for a while before overheating :/ so the problem is not completely solved.

The RPM Spikes up and then down. it keeps trying to turn itself on, like before.

For me, it still doesnt work.

No problem. Sometimes stormworks handicaps some stuff. Thanks for fixing the issue though, i've been trying to figure out why it hasnt been working. keep in mind, i've never actually built anything. (the funny thing is i've had this game for 3 years, and i still haven't figured out how to build lol)

@shuttleman It appears an update changed the output points for the coolant and exhaust which screwed over the system. I have updated it now, so hopefully it works. If you find further issues please tell me here so I can fix them.

I'll try to reach out to Sierra Fox about this as well.

Thank you for the help, it's highly appreciated :D

The only one that works is the electric engines.

it starts, but less than 10 seconds later, it stalls, and doesnt work.

Theres fuel, but it stalls.
How do i fix this? I have tried contacting the original creator, although nothing works.

@shuttleman, how do you mean? does the engine not start or is there no fuel in the vehicle?

why doesnt the diesel work?
