My car can't start after it has been left, without being used, for one month,why is this happen?
Answer:
Weak battery relying on being run to keep it fully charged would be my first guess. Does it start and run when jumpstarted?
Definitely scientific, the battery is most likely drained.
First off...if your car has been sitting for a month...check the battery...have it tested to see if it's still good.
Does it still have gas and oil?
After you have checked all of these...see if getting a jump start would help kick over the engine and let it warm up a bit..
Good luck !
My money is on a bad battery, that isn't holding a charge effectively anymore. Jump start the sucker and if it starts drive somewhere and buy a battery.
If you are going to leave your vehicle idle for such a length of time, it might be a good thing to disconnect one of the battery terminals (normally the earth terminal). Failure to do so might result in your battery power falling as a result of gradual current leakage through the terminals.
Your car failing to start promptly on cranking could be due to low battery power or insufficient fuel (gas/petrol etc) in your carburettor or fuel injector system. Where there are small leakages in these systems, fuel is likely to leak away or evaporate when the vehicle is idle for long periods.
The battery would be the first thing to check. It is possible that it can be drained within a months time since it recharges itself through the use of the alternator, which only runs when the car is on. Try to use jumper cables to jump start it, (also make sure there is enough gas left in the tank). If that doesn't work, take the battery to Auto Zone/Walmart or something like that and have the battery tested for free. They will tell you if you need a new one of if they can recharge it there. Most places recharge for free as well. If the car sounds like it wants to start but all you hear is a clicking noise. Your starter might be going out or you have a bad solenoid. If thats the case, try tapping on your starter with a hammer/screwdriver something like and try starting your car after that. If you can't find the starter, just follow the positive cable wire from the battery, it connects directly to the starter. Auto Zone, O' Riley's...ect. also check starters for bad solenoids for free. If the car turns on but won't stay on, it is possible that you either have a bad alternator (maybe the brushes inside your alternator have worn out and need to be changed; that would be way cheaper than buying a whole new alternator), or you might have a vacuum leak. If the car starts and then turns off, you also might wanna try changing the idle. Find a nut/bolt that connects to the accelerator cable and adjust it a little bit until the car stays on. Thats a good temporary solution, but I would still check into the alternator and hose. Also, check the fuses to see if any have burned out. Just some suggestions. Good Luck with your car!
