Most of the electrical energy needed to start a car is used by the starter. In fact, very little electrical energy is needed to produce a spark and fire the injectors. Usually an alternator can produce enough energy, even at low RPM, to provide power to ignition, computer and fuel pump. The total amperage of those devices may amount to anywhere between 1 and 5 amps. A typical starter can require anywhere from 75 to 200 amps, depending on the engine and starter condition. Pushing a vehicle with a manual transmission allows the engine to turn, replacing the function of the starter.

Can you use a rolling start if a car with an automatic transmission will not start?

You can if you put it in neutral and push it to get a good enough start and try starting it and if it does then try to put it in drive and go yes and no you can not push start an automatic car. but if you can get it up to about 35 to 40 mph and put it in drive it will work but it is not worth the trouble . I would NOT do this unless you want to take the chance of buying a new transmission. You can not push start todays automatic cars. The engine drives the transmission hydraulic pump, not the driveshaft. Only the early Hydramatic transmissions from the 1940's and 50's you could push start if you got the vehicle up to aprox 25 mph or more.


How do you start a car with auto transmission with bad starter?

You don't. You replace the starter and then start the car. In the past with older cars you could push start the car with an A/T and it would start at around 35 mph, but with modern transmissions I highly recommend against doing this. You may damage the transmission.


How do you put a push button start car in neutral without starting the engine?

I can't say all cars have this, but a lot have a release at the gear shift on a floor shift. There may be a small cap over a pin you push in, some have a button on the top of the console. I would think having the key on or in the run position so that the radio worked and stepping on the brake would allow you to shift.

How can you start your car if the starter is bad?

Manual cars can be started with a bad starter due to the ability to roll start the car. Automatic transmission cars are not so lucky. To roll start a manual car all you need to do is put the car in gear with the key in the "on" position, push in the clutch, get the car to roll, then quickly release the clutch. The transmission will slam into the engine and force it to turn. Don't forget to push the clutch back in once it starts or the car will stall.

How can you start a vehicle with a faulty starter?

You can push start it, but with cars today that have no real bumper this is not an realistic option. If it is manual transmission put it in second gear, turn ignition on, and have some men push it. Pop the clutch as soon as it is moving at least 3 mph. On an automatic you would have to be doing at least 20 for it to start. Why not just replace the starter.

Can a manual transmission car be push started without a battery?

Not in any car built since the 1960s and not most of them.Up until the 1930s cars were commonly equiped with Magneto ignition systems and they did not require a battery. Commonly these were hand crank start cars.Into the 1960s cars were built with generators rather than alternators and some were self energising and would power the car once the engine spun up on a push start.
