I have a question, I have a 2002 pontiac grand am gt, and it wont start. I have already replaced the starter and solenoid, and cleaned the battery terminal connections. I have also checked all the fuses. when i turn the key to the on position, all the lights, and power windows and radio work along with everything else, then when i turn it to start everything dies and doesnt work. like i said, i already replaced the starter and solenoid and double checked everything that i disconnected. What else could it be?
