Default Strange starting issue

I have an 03 Z06 and a strange starting issue. Sometimes I will go to start the car and I turn the key and nothing. The gauges and lights are normal. I can start the car by jumping the tdr or if I hold the key in the start position for anywhere from 5 to 45 seconds all of the sudden the car will start. Usually after that the car will start normally for a day or maybe more. I have replaced the ignition switch and the tdr relay. The security light is not on. Any ideas?

Any codes? When this happens, have you checked for 12 volts on the purple wire...at the solenoid.

No codes and 12volts on the purple wire.

Just to confirm. You get 12 volts at the starter solenoid (purple wire), when the key is turned to start (clutch in), and the engine does not rotate?

Ok. So now it's isolated. Make sure you have 12 volts on the large red wire to the solenoid. If so, you have a bad solenoid/starter.
