No crank click sound problem then starts fine

[fixkick]

the ignition key has a wire called the starter wire, or key line
when you turn the key the this wire goes from 0v to 12vdc.
then this wire goes to the PRNDL switch.
if this switch is in park or neutral, 12vdc goes to the solenoid. and this solenoid engages the pinion and energizes the starter motor. all at once.
if it cranks in neutral or park wiggled, the switch is bad.
if the 12vdc does not reach the solenoid , it has no hope of cranking over
if wiggling the cables up top. cause it to crank then the cables are bad or not tight. on all 4 ends.
the only way to prove and intermittent is with a voltmeter, or parts swaps, and pray.
