Check your fuses and circuit breakers. Could also be a bad ignition switch. Check your firewall connections for corrosion as well.
my 91 Chevy Camaro RS V8 engine will not rotate when I turn the key the battery and the starter have been checked
Have you had the Battery checked to see if its still good ? Sometimes just one cell in the battery drops out of the circuit and you have to dice the battery and get a new one. Cheers.
Any time you disconnect the battery the computer automatically reboots,
Have you checked the glove box?
take the battery terminals off and clean them and the battery mountings on the battery real good and reinstall.
check battery. check starter.
Locate the wires that run to the wiper motor and check them for continuity. If not that, hot-wire direct from the battery to those wires to see if the motor is burnt out.
Have you checked the fluid level?
Check in the trunk where the spare tire should be.
Clarify please, 2 cables go to 2 terminals on battery.
usually a bad wheel sensor, get it checked out.
it is on the radiator, midway down on the passenger side. by the battery. Might have to get the battery out of the way to get to it.
