So I leave work today and for about 1 second into accelerating the car starts to hesitate and then dies completely. Well I pull off the road (which sucked without power brakes and steering!) I pop the hood tp find the negative ground cable had come off and had melted the terminal. I try to see if I could get it back in and see if the car would start and it was a fireworks show! Tested the battery and it was showing 12.6 volts and holding. Well gpa showed up with a battery and it too started arching when we attached the ground. Checked all fuses and non were blown. I am stumped. I figure its an open somewhere but wouldnt know where to start with the EFI system! Anyone have advice or previous symptoms?!

 

Did yout starter solenoid hang up and keep driving your starter motor? That is about the only thing on your car that would pull enough amps and not have any over current protection to melt lead along with causing massive arcing.

 

hook the neg cable to the battery first then the positive. if you still have major sparks, this means you certainly have a short. Check the back of the alternator at the main positive cable, check your starter motor cables, check all ground straps and connections.

 

As you aren't blowing fuses or fusible links, sounds like the pos batt cable to starter/alt, or alt terminal is shorting to ground somewhere.
