I'm so confused!
 

i have a diablo predator and all I did was plug it in and read some shit and unplugged it....now my car will not start? wtf

What does it do when you try to start the car? Does it click and try to turnover or does it not do anything at all? Do you have lights and power in the car?

You might have blown a fuse so check those? Also, if your car has some sort of anti-theft built in sometimes those can get fussy and not let you start the car at all. If the fuses are ok, try disconnecting the battery for about 20 minutes and then trying again (this of course if you have full power to your lights and dash).

Is your car showing a security light?????

like it tries to turn over and yeah I have a security light, tcs seat belt, and check guages
