Starting problems. Yay.
 

Alright, I know my battery is pretty much dead but I don't think that's the cause of this problem as when I turn the key, the engine attempts to turn over but after a second or two it stops and it sounds like the spark plugs are firing but the engine doesn't start. It sounds like a welder going off in my engine bay is the best way to describe the sound.

So.... What's fucked up. lol

starter possibly?

take it off and go get it checked at autozone

is it a really fast ticking noise that is pretty loud?

Yeah, it's pretty loud.


If the starter was bad wouldn't it not turn over at all?

Sounds to me like your battery is toasted and you need a new one that should fix it


Try getting it jumped if that works it's the battery and if it runs for a while and then dies it may be the alternator too

Tried jumping it from our tahoe but it had the same issues..

Are any of the warning lights on?

Yeah, 100% on the engine bay. I'm going to run to autozone after class and pickup a new battery. Then I'll post an update.

Sometimes a battery can get so bad that it can't even be jumped. If you know that your batt. was bad get a new one and replace it then take it straight to your local parts store and get them to run an alternaor test it should be free at autozone

Well if I put the new battery in, it starts, then drive the car to autozone to test the alternator, wouldn't I already know it's working since I was able to get the car there? lol

Your alternator could be on the verge of totally failing but still working a little I had the same thing happen and it killed a perfectly good battery. I thought that battery was going cause I kept having to jump it but the alternator had stopped charging it well cause it was on it's way out the door. I got a new alt. and every thing worked great but the damage had already been done to the battery and once it got cold here I had to replace the battery.

When it happened to me my alternator was rated at 130 amps and it was putting out a whopping 7 but it will still charge that battery if you have at least half what the alt is rated at

I just read that you upgraded your sound system that would be more than enough to over tax an old alternator

Alright, well I'll go get a new batt and have the alt tested..fucking mustangs. lol

Alright, replaced the battery and it all works fine now. Did an alternator test and it was running at 85 amps..what's the stock amperage supposed to be?

i think it is 85 amps. not very much..

WAIIITTT!! u hooked a soundsystem up without unhookin the battery!!

No, the battery leads were unhooked throughout the install.

Sweet man, glad to hear it all worked out. Might wanna get a higher capacity alt ;)

Stock amps is 130

You can check the alternator these 2 ways. The first check the voltage on the battery or at the alternator while the car is running. You should see the voltage staying steady from 13.2 - 14.7 volts if you see it slowly dropping you may have an issue with the alternator.

The other method, which isnt the best but works, is to start the car with the negative battery cable loose enough to be pulled off but tight enough to start the car. Start the car, pull the negative loose cable off. If the alternator is bad the car will stall. To check even futher turn on headlights, stereo, heater fan, and other electrical accessories to increase the draw on the alternator. This can help you to see if the alternator is a little weak.

at 85 amps it is a little bit weak and the new sound could cause charging issues

that may be right... mine didnt come with mach audio.. so i think mach audio equipped ones have the same as a 4.6

I love it when people make posts like these. "My battery is dead but I dont think thats why the car isnt starting!!!??!?" It must be something other than the dead battery. I cant confirm its not the battery because I have not replaced it yet though!"

like wtf, did you really have to make a post about it? I mean maybe im being too harsh but does not logic tell you to replace the stuff you KNOW isnt working before you assume its something else. Sorry maybe im just taking my frustration out on you because I deal with people like you all day long, but dealing with computers. Troubleshooting is the same no matter what your working on lol.
