P1684 is just telling you your battery was disconnected within the last 50 ingintion cycles. (starts)

I think both you batteries are junk or your connections are. If you terminal connection look good then sand down the posts and connectors a little to give it a better contact area.

 

does anything light up in the car when u turn the key?

if not, first try to jumpstart the car, if the charge doesnt hold then u prolly need to get a new batt.

 

yea all my lights work fine... my dad is saying that the starter is the problem.....

 

but what bothers me is the crankin sound my car makes when i try to turn it on....

 

does it crank really slowly or is it a normal type of cranking? if the cranking is slow it means there isnt enough juice for the starter to turn over properly.... and also turn off the Defroster as well as the radio if they are on and listen forthe fuel pump.... what also could have happend is you got some crappy gas that could have frozen in the fuel line somewhere... not likely but its a possibility. first thing i would do would be to check all of my fuses and then i would try to jump the car...

 

you could always try to jump the starter... i don't recomend it but i've done it a million times. Had a junk starter in my 1st gen for a while. Jumped it with a long screw driver every morning and afternoon for a week. My co-workers thought i was nuts. It's also a good way to tell if its junk.

 

i wouldnt suggest this unless you know what you are doing though.... just a sidenote, it also shouldn't be the first thing you do either... but if you could give us some more details about what happens when you turn the key it might help....

 

when you turn the car over does the engine crank over or does it sound like something spinning fast (starter not engaging) or does the car hardly crank over?

 

Thank you guys it was the battery... it had no juice left... lol

 

its all good man! congrats! it happens to the best of us no worries
