I charged the battery for about 90 minutes. When I turn the key, I get a humming sound. The battery and alternator are about 3 years old. I am able to start the car by shorting across the solenoid terminals. Any suggestions out there. Thanks!

Re: starting the car
You can typically bring your car into Sears which they have an electronic testing device that will allow you to hook up the car. normally they do this for free a few years ago. I'm not sure if they changed it. It will show you if the power is even passing through.
Most of the time you might need to clean off the metal clips that hook onto your car battery since it can build up gunk and doesnt allow the electricity to pass through. Otherwise you might need to change the spark plug which has been a simple fix to what you are also explaining.
Are you also hearing a ticking or clicking noise but it's not turning over? Has it gradually done this over time but now not turning on at all? Then there is a high change you might need a new spark plug.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

it sounds like your battery charge maybe low. turn on your headlights and verify that lights are bright while starting car. if lights are weak, you need to check the battery voltage. a cheap multimeter will tell you what the voltage is. If battery is good, check your starter relay. Also try jump starting your car with another car. if it starts then you know its not a bad starter relay or your starter motor. if the car starts keep your multimeter on the battery and make sure your reading about 14 volts. that will tell you that the alternator is working right. shut your car off and monitor the battery to see if the voltage starts to drop. it should read about 12 volts. if it drops to below that immediately your battery is not holding a charge, or something is draining the battery. if it is not holding a charge; try jumping the battery again while the positive cable is not connected to the battery. then check the battery to be sure it is holding a charge. If the battery holds a charge, you need to find out what is draining the battery while connected to the car. When you reconnect your battery, your alarm may go off, so have your remote handy. on most cars you can turn alarm off simply by unlocking and locking the doors with the remote. You can usually find what is draining your battery, by removing fuses while monitoring the battery. the battery will stop draining when the suspected fused circuit is pulled. You also want to make sure that your trunk light, or interior light, is not ON and draining your battery. Many people with remotes will on occasion find their trunk open, which will drain the battery overnight. Hope this helps. Good luck.
Hi Kelly, A fully charged battery is 12.4 to 12.6. and when the motors running it's 14.3 to 14.6... Three reasons your battery is flat (isn't charging), You have a faulty battery, A power drain or you have a faulty alternator... Clean your battery terminals and If you don't have a multimeter then Try jump starting your flat battery and driving your car for at least ten minutes then turned the motor off and try starting it WITHOUT jump start, If the battery's still flat then it's the battery, If your car starts straight away but won't start the next day then you have a power drain... If you jump start your flat battery and go for a ten minute drive but during that drive the motor dies without turning off the key then it's the alternator....
A mechanic or an auto electrician can usually test Free of charge if you can get it there....CHEERS..
the alternator isn't charging battery that would account for loss of power and also clicking when try to start , try a jump start if it starts then you know its the battery so with engine running check the alternator charge rate with a voltmeter across the battery terminals anything below 13 volts then check the alternator belt is tight enough , good condition etc , then recheck charge rate if still low fit new alternator
yea sounds like a bad starter, in the cold it will not make complete contact when soleniod triggered.. this is due to worn contacts inside, when warm it makes a better contact, if you replace the starter this will solve your problem, also have the battery and alternator tested
The Alt is okay but the battery won't keep a charge? Replace the battery. At least take it to an auto parts store, and have them do a load test.
Your fuel pump is electric. When you turn the key on it pumps up. After it has developed the needed pressure, it no longer pumps, hence you won't hear it working anymore.
Diagnose your problem going through the various systems. Right now you have a problem with the starting system. It sounds like, from your explanation, that the battery is bad. If your battery checks out, and then you have the alternator checked out, you have an electrical drain. This may be tough to find.
After you replace your battery, wait 10 minutes, then try to start your Camaro. If it doesn't start, (Key to the Off position), take the Positive battery cable loose. Wait 2 minutes, then reconnect it. You are resetting the computer.
The most likely cause of your problem is your alternator and/or battery. You can have them tested at most any auto parts store for free. One of these two things will fix this type of problem 90% of the time.
