A month ago, my battery was CAKED with corrosion and wouldn't start. I deep cleaned connections and car would start up GREAT after that. Terminals never corroded again. Then, randomly on wednesday, i tried to start it up before work, dashlights blinked and died, car wouldn't start. I tried to start it the next day, nothing. Decided to take battery to autozone to test, they told me it was 90% charged and it was good. Took it home and tried to jump it to make sure, nothing... no crank, no click... NOTHING. Tapped on the starter as well. Nothing. Checked fuses in the hood for ignition and starter fuse in the kick panel... all good.

any ideas?

 

Clean/check connections at trans ground, g101 (thermostat ground), positive connection from battery to starter and report back.

 

replaced starter ground, it's fine. will check g101 and trans ground tomorrow.

 

what starter ground?

 

Sorry, I meant starter to battery connection is fine.

 

as i can see from your video you have no lamps when the key is at on (check) place.

if this is the problem than it seems you have no voltage from battery.

turn your key to on place. Do you see lamps lighting on the the instrument panel?

 

Youre correct. No lights, no sounds.

 

1. battery unpluged-or bad contact
2. battery low voltage
3. engine main ground is unpluged
4. short circuit

i suggest you to check the above at given sequence

 

Thanks. Im grabbing a multimeter in a couple hrs.

 

Clean and tighten the battery ground connected to the chassis.

Also check the 80A hood fuse.

 

thanks thats exactly what i ment by "engine's main ground..."

 

Checked 80A fuse, hoped it was the culprit, but it was good.

 

all fuses were 0.
battery was 12.4v.
battery cables/grounds have been upgraded to 4 gauge except the positive battery cable power to fuse box (which looks flimsy and thin, corroded) and transmission. Transmission cable looks great.

Positive battery cable to fuse box...

 

my god this is realy a f..up wire

its difficult to make all these new connections. you must have the wirings diagram, better get a used wire from an exactly same model as yours and replace it...

 

Yeah I I just need one more lug to connect the wire. Ill update after i test it out.

 

Tried to re-install the new cable and stripped the thread of bolt and hole thinking i didn't tighten it so well x___x any suggestions on how to fix it? it was my last step and now i'm set back

 

before all this happened since you weren't getting a click or anything did you check the starter solenoid??? replace it???

try re tapping it. or getting a little bigger bolt/tap.

 

use a slightly larger self tapping screw/bolt

 

Done. It worked finally. It was that stupid wire. now car is very responsive with alarm and at start.
