Check Your Fuses: Few cars have a fuse associated with the starting system, but before you go monkeying around with everything, check your fuses to be sure it's not that simple.
Battery Corrosion: Over time your battery connections can become dirty, or corroded. This corrosion breaks the connection your battery has with the rest of the car, and it won't start. Try cleaning your battery posts and try to start the car again.
Dead Battery: The most common reason your car won't start is a dead battery. If you have a battery tester that can measure cranking amps, test your battery to see if it's weak. If you can't test it yourself, you can test the battery indirectly by jump-starting the car. If it starts right away, your problem is most likely a dead battery. Replace the battery, and clean the battery connections to ensure good contact.
Bad Igntion Switch: If your battery checks out, but the starter is still silent, it may be a faulty ignition switch. Turn the key to the on position (not all the way to start). If the red warning lights on your dash don't light up (and your battery connections are clean), the ignition switch is bad. If they do light up, turn the key to the start position. The dash warning lights should turn off at this key position (most cars). If you're not sure, turn on the headlights. When you try to start the car, the lights should either dim (a lot) or turn off completely. If they do, your ignition switch should be ok. If not, the switch will need replacement.
Bad Starter Connection: Corrosion can not only keep your battery from connecting, it can affect any electrical component, especially the ones exposed to the elements like the starter. If you have a helper, you can test the connection by holding a circuit tester lead on the wire that engages the starter. This is the smaller of the two wires connected to the starter. Be sure no part of your body is near the moving parts of the engine - it could still start at any time! Have a friend turn the key and check the current. If you're getting current to the starter but it ain't spinning, it needs replacement.
the answer your looking for is sure it could be but is it? you need to check the basic's to see why your car is not starting. i always start with make sure the battery is turning engine over fast enough with proper power... then check the spark at a spark plug, then check if your getting gas. slowly narrow it down to one thing or the other cause there is many things that can be wrong from sensor's, fuel pump, low or bad battery which could mean a bad alternator too since the alternator is suppose to be charging the battery when engine is running... many parts could cause ur problem so u just got to narrow it down a lil bit more keep narrowing it down till uve found the problem without putting money into it. no one likes replacing parts on a whim for no reason.
That is why you try a new battery first, or jump it from another car battery. If car starts then it is battery which is so simple to change, even you could do it.
Year of car and year of battery helps for us to know. Batteries last about 5 years and they always seem to fail before the first snowfall.
Do the lights go on, if bright then battery should be OK, but if very dim them battery flat. Turn lights on and get someone to try and start the car. Watch the lights and they will go dim if flat they probable virtually go right out, which is flat battery. Maybe you left something on and it needs a jump start.
Need more information.
If it makes any noise at all? Click? does it try to start?
If there is no power at all to the lights or power lock then it is the battery.
Try boosting it.
Check to see if the cables are still attached to the battery. I know with my car (1997) there was a time where the ground wire became loose. This was an easy fix though.
please add more information.
Have the battery *load tested at any store that sells new ones other than Auto Zone. A free 15 second battery load test will tell the reserve amperage capacity. Amperage spins starter motors not voltage.
Why, yes it could just be the battery. It could be that the battery is defective or discharged. It could also be the starter, solenoid, wiring, or start switch. Since you gave so many details, it could also be out of gas or the engine could be damaged or have a defective part too.
Sure, it could be the battery! Or one of 100 other components.
Ask a vague question . . . .
need the car information and what it sounds like
