I'm having this issue and its causing a lot of stress as I have to drive to work everyday. My car does not crank and wont start, for me to get it to start, i have to turn the key once, put it into gear and push the car back and forth until it turns on. After i get it to turn on once, itll turn on again with no problem at all. But the second i move the car and turn it off is when it wont turn on anymore. This actually started happening after some A-hole crashed into the front bumper on the drivers side while i had it parked on the street overnight. The damage is mostly to the bumper, checked under the hood theres no cracking nothings broken everything looks as if it should. Just doesnt start unless i push. Any ideas please? ive been doing research and it could be a number of things but maybe considering that the crash is what caused this maybe you can pinpoint the problem faster.

 

You will have to start checking things as there can be many reasons for your problem. You could have a battery problem. You could have damage to the relay box in front of the battery. It could even be a starter or ignition switch problem.

The first thing to do is check the battery voltage before you try to start the car. It should be around 12.5 volts, but not below 12. When the engine is running, the voltage should be around 14.3 volts.

If the battery is ok, then remove the air filter box so that you can access the starter. Connect the voltmeter to the thin wire that goes to the starter. When you turn the ignition switch, you should get 12 volts on this wire. If you get 12 volts and the starter does not crank the engine, the starter is bad.

 

First of all, you might dealing with co-incidence, not cause and effect. Don't see how the bump could cause that.

Do you have an automatic or manual transmission?

If it is an automatic, try starting in neutral install of park.
