Quick fixes

What’s getting in the way?

Start with the problem you see. These checks lead to the relevant instructions and a useful report if you still need help.

The game will not start, or the mod is missing

Choose the release for your exact Minecraft version, then check its required Fabric Loader, Fabric API and other dependencies.
Put the mod and its required files in the mods folder of the Fabric instance you actually launch. Remove older duplicate copies of the same mod.
Check the Java requirement shown for your selected release. The versions you selected on Offchunk are shown above when available.
If the game still fails to start, keep the relevant error message and the versions you used for your report.

My service pump has no fuel

Sneak-right-click with an empty hand to check the pump setting, stored fuel type and amount.
Add matching petrol or diesel by holding right-click with a filled can without sneaking. Changing PETROL, DIESEL or AUTO does not transfer fuel.
An empty AUTO pump accepts either fuel. Once stocked, it keeps that fuel type until drained.
Breaking and replacing a pump does not preserve its stored fuel.

My pumpjack is not extracting oil

Use the survey kit and place the pumpjack inside the discovered field region.
Apply a redstone signal, keep its chunk loaded and empty the buffer when it is full.
Oil reserves are finite and shared by all pumpjacks in the same region. Check whether the field has run out.

My car will not refuel

Install Pumps & Pistons, Automobility and the separate fuel integration. Follow the integration’s required versions; they can differ from the newest releases.
Install the same versions of each mod on the server and every client.
Match the engine’s fuel: stone, copper and gold use petrol; iron and diamond use diesel. New vehicles start empty.
With a service pump, take the nozzle with an empty hand and click the vehicle once. Stay within reach: six blocks by default. With a jerry can, hold right-click instead.

Autoradio is silent in Minecraft

Start with a working Automobility car and check Autoradio’s installation requirements. Use matching Minecraft, Automobility, Fabric Loader and Fabric API versions.
Hold F7 to choose a station, then release to tune in. Check your key bindings if another mod uses the same key.
If the problem continues, tell us whether it affects included stations, your own tracks or both, and whether you are playing alone or on a server.

The website radio preview is silent

Choose a station and press Play preview. Turn radio off disables playback.
Check the preview’s Volume slider and whether your browser tab or device is muted.
Previews stop after 20 seconds and pause when you switch tabs or open the installation window. Press Play again to resume.
If a preview reports an error, try Next preview or another station.
