Car won't turn on
 

Hey guys... so this happened 2 weeks ago, and it happened again just now.

The very first time... When i tried turning on the car, it would make this rattling noise and wouldn't start up. I made an effort to keep turning on the car but i wasn't getting anywhere so i stopped. After about an hour wait or so, it finally turned on.

TODAY... it would not turn on at all. For the past few days when I tried starting the car, it seemed like it was struggling quite a bit. And today, it would not budge at all. I've been hearing this may either be the battery, fuel pump, or the flywheel problem. do you guys have any idea or have had this problem before? i'm wondering if this is a common problem for z's.

i have a video link attached for you guys to get a clear idea of whats happening. help pleaseeeee!!

hows ur battery and alt?

i'm not sure because the lights, heaters, everything works....

battery

I just tried jump starting it....and it didnt work.
It does not even make the rattling noise anymore and my honk sound for some reason sounds a bit awkward (weaker than before)

miles how often is it driven ? mods?

im positive that its the battery that is going bad. it seem like it is providing enough voltage for the gauge and radio but doesnt have enough cranking amps to turn over the engine. jumping it wouldnt help either (trust me ive been in that position). head down to an auto part store and buy another battery. if thats not the case then you can always return the battery. goodluck

Agree. Specially if the OP is still on the OEM battery. Mine started to go after 6+ years. Starts/cranks started to go slower and slower. I really never payed much attention to it until one day...it really hesitated. Still had enough juice to power lights etc. Looking at the OEM battery, it had some fill/service holes, and it was pretty dry. I went to Autozone and picked up a new one, and it fired right-up. Really strong to the point it made me realize how weak my old one was getting.

same thing happened to me all the light would work but the car wont crank went to auto zone and got a new battery and its starts every time now

u can go to advanceautoparts online and buy a battery with the coupon and you will get a 50 dollar discount for future purposes.

Thanks guys, it WAS the battery. I jump started 4 times with two different cars and and the last one finally made it start up. As soon as I was able to drive I bought a new battery :) thanks for the help guys, appreciate it. Cheers!

Always good to get a voltage reading at rest (12 volts) and while the engine is running >14volts...just to make sure the alternator isn't failing.
