Will it even crank? If it won't, you have an ignition switch or lock cylinder going bad. If it does crank, just not running, then check to make sure fuel pressure is good and that the ignition coil is good. When exactly will it not start?
could be the alternator. could be the battery, the alternator charges the battery but does not stop the battery holding a charge.could also be a bad starter motor. take alternator off and have it tested. most places will test for free
It could be poor battery connections, the starter,
Starter problems can be caused by several things: Weak battery because of battery failure or alternator that is not charging the battery. Falty connection between the battery and the starter. Solenoid failure or bad connection on the solenoid. Starter failure. Neutral lockout switch failure. Bad connection between keyswitch and starter.
The problem is not the starter. The battery is either not holding or not receiving enough charge. Problem could be (1) loose alternator beltl (2) loose/corroded battery cable(s); (3) dead cell(s) in the battery; (4) bad alternator.
Check the battery, it might be low. A low battery can be caused by either an old, worn out battery or by a faulty alternator. If the alternator isn't putting electrical energy into the battery, the battery won't get charged. After all, a battery is only an electrical STORAGE device. If your battery is fine, you might have a weak starter. You should also check your ignition switch. Try disconnecting it, and then touching the female end to the battery. This grounds out the circuit, should start your car for you, and tells you your battery and starter are perfectly fine.
your starter might be going out does it click if so its your starter if not than maybe battery if not battery than its the alternator
weak or faulty battery, faulty alternator (or slipping alternator belt causing battery not to charge) or faulty starter motor
Indirectly. The positive cable on the battery is hooked to the starter. The other wire on the starter post goes up to the alternator.
Starter solenoid.
Is it charging, if not have you checked wiring to alternator.
There is not a fusible link between the alternator and starter. There is a regulator on the alternator. The starter is directly connected to the battery, as is the alternator.

Alternator on a car is for re cahrging the battery. So you can have a starter motor without a alternator but you wont get far down the road when the battery runs out of power and the car will die.
There is a wire from the alternator to the starter motor. On the starter motor end, there is a fusible link that sometimes melts. With the engine off, check the battery volts and check the volts on the big red alternator wire. If they are not the same voltage, the link is open. If the link is open, the battery will not charge
YesFirst if the starter is bad the car will not start, if it will not start it can not charge the battery.If the starter will not work it can mean there is an electrical problem that will also prevent the alternator from charging the batteryThe starter itself CAN NOT CAUSE CHARGING PROBLEMS!The extra load on the battery can ruin the battery and that can ruin the alternator. But before that NO.
No, your battery supplies power to the starter. However if your alternator is defective then it will not supply power to the battery and the battery will soon be depleted.
