However – there are some things you need to consider.Ī diesel engine uses heat and high compression to ignite the fuel. I drive a diesel – and I’ve had to bump start it once or twice without issue. A diesel manual will react in the same way as a petrol manual if you try to bump start it. With any luck, once you reach 10-15mph your engine should start. Take the handbrake off and pull the clutch up to the biting point.If second doesn’t work you can also try third gear. You do this because second gear will engage at a low enough speed, but also you won’t need as much torque to get the engine going in second as you would in first. Switch off any ancillaries or anything else that might put a load on the battery – this includes radio, air conditioning, fans, heater, lights, etc.If you need some helpers to push you along, make sure they put you in a position where if you start rolling, you won’t crash into any other vehicles or pedestrians. If you’re on a hill, make sure you can roll the car without hitting anything.Don’t try to do this in an automatic – you need a clutch pedal in order to bump start a car. It goes without saying that you can only do this in a manual car. Putting the car into gear connects the engine and gearbox, and while you are rolling, slipping the clutch allows the wheels to turn (they’ll be locked if the clutch is up, and you’ll just coast if the clutch is in.) Rolling the car means that instead of the starter motor turning the engine over, the rotation from the wheels actually turns the engine over. However if your battery is dead, your starter won’t work, as the energy required to run the starter motor comes from the battery. When you start your car normally, the starter motor engages and turns the engine over. Bump starting a car basically means putting the car into gear and either rolling down a hill or having some willing volunteers push your car. Firstly – what is a bump start?īump starting is also called “push starting” and is sometimes called “clutch popping”. In this article we’re going to go through whether you can bump start a diesel and how you should do it. Generally it’s accepted that bump starting a petrol is no problem, but there seem to be some reservations and concerns about bump starting a diesel. However, there is another way to get your car going if you’re stuck, and that involves either a hill or a group of people willing to push your car, and that’s bump or push starting. And that’s if you’ve got any jump leads – if you don’t you might be a bit stuck. So now we have to go through the pain of either calling a breakdown service to get you going, or flagging someone down to try and give you a jump. We’ve all been there – we get into the car, push the clutch in, turn the key in the ignition, and… nothing.
