Crank but no start.
 

Thats corrosion. Remove that battery and clean it! There's plenty of explanations on how to clean it.
And as for other, not starting, explain what happens when you go to start the car.
Does it turn over?
Noise?

EDIT- yes it could be the battery, the corrosion could have damaged the cables or battery itself. The battery doesn't need much to power the lights, hence the lights working.

It Just doesn't turn over.. thats the only way i can think of describing it.. i cleaned that stuff off when a metal brush but I didn't take the battery out.. Im gonna get the battery tested but that won't be until I can get a ride n that won't be fore awhile so I'm just tryin to trouble shoot

Does it just make a clicking noise when you try to start it? If so, your battery is just dead....Either get a jump start or bump/push start if you have a manual, take it to an autoparts store and get the battery tested and replace it if necessary.

Well it's best to start with the easy fix first so def check the battery!
How old is the battery? Has it sat for extended periods of time without driving?
I'm putting my monies on the battery, mines on its last legs >_<

hasn't sat but the battery is old .. nope there is not clicking sounds n it couldn't be jumped

Ok so what happens when you try to start it? Nothing? Or is it Cranking, as in the engine is turning over and it's just not starting?

to be honest i bought my car in 05 n i don't ever remember replacing the battery.. im pretty sure thats the factory battery

3-5 years is the average battery life span and like I said its easy to power the lights so batteries are deceiving little bastards xD they make you think they have juice but in reality it prolly has barely enough for that!

it just cranks

Crank but no start o_O old battery...
Battery and ignition check to be safe :/
Idk how often you check these things or how you maintain your car but there's a sequence to starting your car. If its not A move on to B then C etc.
But start where it's the cheap and easy fixes first!
Test battery and then ignition I say

I have a 04 I just bought in january. Took a trip to texas and while there started having trouble with starting. Looked at the battery and it was the original. My luck the only parts store was Oriley's and I paid $129. plus i had to replace the cable ends too.

If you have a lot of crap growing on the terminals, you prolly have a poor connection too.

Take the clamps off the posts and clean them both with sandpaper (or your nail file, whatever.)

Spray some oil, WD40 or such on both then clamp them back up.




Title changed, pleasee helppp is not a proper title.

If it's just cranking, it's most likely just flooded.
