My Camaro has been sitting for about 5 years in a garage and I am trying to get it started. Here is what I have accomplished. All of my lights work as they should. Radio works. Wipers work. Instrument lights work. Directional indicators do NOT work. With key in OFF position, there are NO warning lights. When I turn the key to ON I hear a light thunk sound that comes from the voltage regulator. When the key is turned back to OFF, the GEN light is on. I can get the GEN light to go out by unplugging the two wire plug from the back of the ALT or disconnecting a battery cable. I removed the voltage regulator cover and watched what was going on when repeating the key switch from OFF to ON. The single contact points is what is pulling in and making the light thunk sound referenced earlier. I switched the key from ON to START and had nothing......no solenoid click, no starter motor.....nothing. I jumpered a wire from the POS of the battery to the S terminal on the starter solenoid. The solenoid clicked but the starter did not turn. I checked the battery voltage without cables connected and had 12.5 volts. With cables connected I had 12.5 volts. I removed the starter and solenoid from the engine and took to Advance Auto for a check. The starter motor spun and the current draw was about 120 amps. So after all this effort, I am out of ideas. The Advance Auto employee suggested that maybe the engine is stuck? I had thought of that but not sure why that would have happened. The car sits in a garage with a car cover. A week ago I changed the engine oil and filter then pulled the distributer to prime the oiling system. Spinning the pump with a cordless drill I had 36 psi pressure. I know I have listed a lot of things in this post but it paints the picture. I am now wondering about the neutral safety switch. The car has a 700R4 with a B&M console shifter. I can see a switch with two purple wires and at least two or three other wires that I presume are for the backup lights? Thanks in advance for any advice or help with my starting problem.
