Someone please help. I installed a stereo system on my 92 LS about 6 months ago, and as I put everything back together, the car wont start cranking. Every part of the car is recieving power since the dash, exterior/interior lights work perfectly well. I checked the main relay, the ignition switch, neutral safety switch (even though its an automatic). I judt replaced all of those fuses, I diagnosed the safety switch and had no issues. I just replaced the starter but it still wont crank.
