68 GTO won't start
Chicken **** wiring in the engine bay. Some in the interior. Pulled out the radio and corresponding wires. Other wires that did not attach anywhere where yanked as well. Many splices. Have a new battery and checked the cables. Accel coil that I am not sure is connected right either. When the key is on I get temp and gen lights on, but upon start nothing. I get buzzer when door is open and lamp under the dash pad works when swathed on. Where to start looking? Ingition to solenoid? Coil? Alt wiring?

Check for power to purple wire at solenoid when key is turned to start. If yes, check solenoid. If no, follow wire back thru neutral safety switch to ignition switch checking continuity as you go. Could also be something as simple as a poor ground or a dead short, robbing the system of enough power to start. Check battery cable connections and resistance.

Pulled the starter and bench tested it. Could not get the shaft to engage by powering the solenoid. Had a working starter and swapped it in. Could not verify if I am getting power to the solenoid. Need a second hand and no one home.
Do 68s have a neutral safety switch? I thought I read on here the neutral safety switch did not start until 69? Just trying to rule out other problems. The harness to the his her shifter is not hooked up. I have also tried starting in neutral and park. No luck. |

You should definitely have a neutral safety switch with auto trans. If you don't have parts of this circuit connected, the starter will not engage.
When you bench test the starter you need to connect the case to battery negative and need to use a battery as a power source, the starter draws a lot of juice, testing it with a weaker power source won't work. George

Yes the neutral (or Park) safety is on the shifter if an automatic, 4 speed I believe use a switch on the clutch to insure its to the floor for starting. I had a lot of problems with voltage drop on my automatic 68 with that console switch. Finally replaced it and they went away.

Not on a 68. 69 + for manual trans.
