So i just put in a amp and a sub and i have been having some problrms. The other day i went to walmart and was in there for maybe an hour went to start the car but it wouldnt start.

So i undid the amp played with it tried starting nothing so i went to to walk to see if someone could jump me found now came tired it again and it worked i have no clue whats going on



thanks

 

Did the solenoid click or was there the typical low-battery growl when you tried to start it, or did it just do nothing at all? If it did nothing, it could well be related to VATS, the anti-theft system. I had this problem with my 96, intermittent refusals to start and then one day it completely disowned me.

I guess after time the contacts in the ignition lock cylinder that touch the resistor in the key go bad, and rather than replace the cylinder, I just wired in some Radio Shack resistors to fool VATS for the rest of time.

See here and here for more info. The second page also tells how to test your lock cylinder to see if it's faulty.

 

do you have a capacitor in your system? i had my cap accidently drain my whole battery once.

 

no i dont i didnt think i need one.

 

it made no noise at all
