Quick answer
What to do first
Confirm the key or hotwired state, then check fuel, battery charge and engine information. Battery condition is not battery charge, and engine condition is not the same as engine quality. A car that is accessible can still be mechanically unusable. Diagnose the failed stage before consuming parts or repeatedly trying the ignition.
Check your game conditions
- Current Stable
- 42.20.4 Stable
- Play mode
- Singleplayer / Multiplayer
- Vanilla / Mods
- Vanilla baseline; mods may replace rules
- Sandbox / server settings
- Vehicle condition, fuel and environmental settings vary; mod vehicle systems are not covered.
What happens when you try to start?
No usable ignition access
- Possible cause
- Wrong key or incomplete hotwire
- Check
- Dashboard key/hotwire state
- Next action
- Resolve access before replacing mechanical parts.
Battery looks healthy but the car will not start
- Possible cause
- Good condition with insufficient charge
- Check
- Charge separately from condition
- Next action
- Use an appropriate charged battery or supported charging method.
No fuel reaches the engine
- Possible cause
- Empty tank or fuel problem
- Check
- Actual tank contents and condition
- Next action
- Obtain usable fuel and inspect relevant damage.
It cranks but often fails
- Possible cause
- Engine quality/condition or other conditions
- Check
- Engine values, not only the bodywork
- Next action
- Consider a more reliable vehicle; repeated attempts are not a repair.
It starts then stops or barely moves
- Possible cause
- Additional mechanical/drive issue
- Check
- Fuel, damage and the specific new symptom
- Next action
- Stop treating it as a key problem; inspect before driving farther.
Use the vehicle mechanics panel
Inspect the car in a safe location and compare the components involved in starting. Bodywork that looks intact does not establish battery charge or engine reliability. Write down which condition failed before changing parts.
A replacement must suit the vehicle and be usable. If you cannot repair the engine or lack the needed supplies, finding a different car can be more practical than dismantling the current one in an exposed area.
Avoid treating every failure as a patch bug
Older forum fixes often describe one damaged save, mod or version. Recheck access, charge, fuel and engine state first. Only then compare the exact symptom with a current known issue.
On a server, report whether other players can use the same vehicle and whether the issue affects all cars or one modded model. Do not disable security software or remove world content to solve an isolated ignition problem.
Version notes & limits
Vehicle and Mechanics references include earlier B42 material. This guide uses the documented component distinctions; it does not prescribe an exact start-success percentage, weather threshold or historical bug workaround.
Vanilla starting faults, not all driving problems, towing, every vehicle mod or a guaranteed repair for a wrecked engine.
