i parked my car(1991 camaro rs tbi) at my friends today and installed my new radio started the car made sure the radio worked then shut it off, then a lil while later went to start it again to leave and nothing it wouldnt turn over. i went under the car and unplugged the neutral safety switch and still nothing, i already have the VATS system bypassed i did that a while ago i checked and the resisters are still there and soldered together. when i turn the key to on the radio goes on and everything then i turn the key and the radio goes off and nothing else. idk what else it can be and i need this fixed fast otherwise i have to way to school, also i noticed my hatch isnt opening with the switch anymore

 

Did you check the fuses?

 

i fixed it
