Run out of petrol now car wont start could you have an air lock and what do to release it?

Yes, it is possible that you have an air lock if your car won't start after running out of petrol. An air lock occurs when air enters the fuel line, preventing the fuel from reaching the engine. This can happen when you run out of petrol, as air can be sucked into the fuel line as the tank empties.

There are a few things you can do to release an air lock and get your car started:

1. Try turning the ignition on and off several times. This may help to clear the air lock.

2. If that doesn't work, you can try bleeding the fuel line. To do this, locate the fuel line that goes from the fuel tank to the engine. There will be a small screw on the fuel line; loosen the screw until fuel starts to leak out. Once the fuel starts to flow, tighten the screw.

3. If you still can't get the air lock cleared, you may need to take your car to a mechanic.

Here are some tips to help you avoid getting an air lock in the future:

1. Always keep your petrol tank at least half full.

2. Avoid running your car out of petrol.

3. If you do run out of petrol, try to get the car to a petrol station as soon as possible.

4. If you are going to be storing your car for a long period of time, add a fuel stabilizer to the petrol tank.
