Okay on my gsr turbo delsol, doing some 3rdone gear pulls then car dies.. thought it was because of rapid acceleration .. put in 5 th gear nothing car wont start. This point car has no dash lights, power windows wont roll up down I have no power throughout anything other than head lamps and flashers... take in that IFO is Sunday, and this is my drag car... car has no heater ac nothing its fully gutted .. car sees the street only when pulling on trailer... so I was thinking bad ignition switch ... or something ...

 

ground loose?

 

Did you check the main power fuse that is in the engine bay fuse box? Its a 80amp fuse and should be the last one on the bottom. Also if it is that, the only thing that will work will be the horns lol. Hope this is some help. One more thing, if this is the problem you need to look for a loose power source that is shorting out somewhere because that is one of the main things that will blow that fuse. Keep us posted
