Question about 1987 Oldsmobile Delta 88
While the steering rack was removed it is possible that the wiring to the solenoid switch was tampered or detached.
It can also be a case of the ground connection being lost to the solenoid.
So you need to start by checking the main ignition/starter switch. There can be a failure of a line in this section or a failure of contact in the starter switch. Try to short the leads here in the switch to confirm , if so the main Ignition switch is faulty.
If not check the continuity to the switch contacts, if Ok there is wire damage to the solenoid , Trace the harness from the ignition switch to the solenoid to confirm.
Tip: shorting the solenoid with an external +12 will confirm the starter and solenoid.

Welcome to Fixya
This is basically what happens when you turn the key to start position. You should at least hear the starter solenoid click when you turn the key. The ignition switch sends 12 volts to the Starter solenoid ( really just a relay). The Solenoid closes and applies 12 volts (at a high current) to the starter motor to crank the engine. If you have a way to measure voltage, you should get 12 volts at the small terminal on the starter solenoid. The solenoid is mounted on the top of the starter motor. If you get no voltage, probably an ignition switch If you get 12 volts and the starter doesn't crank the starter is probably defective. At this [point take a small hammer and tap the starter motor, not hard, just medium. Sometimes this will cause the starter motor to catch next time you turn the key. I suggest to remove the starter motor (with solenoid attached) and take it to an Auto Zone type store where they can check it out for you. Be sure you disconnect the ground terminal of the battery before you attempt to remove the starter motor.
Thank you for using Fixya!

The power from the ignition switch is sent to a starter interrupt relay and then continues to the nuetral safety switch located on the transmission. Check to make sure that the nuetral safety switch is plugged in. If it is unplug it and see if there is power on the yellow wire when the key is in the crank position. If there is than the safety switch might be bad (you can also see if the starter will work with the gear selector in the nuetral position).
If there is not power than you'll have to trace the wiring back to the starter relay or the ignition switch.
What all did you remove when you replaced the rack? did you drop the subframe or mess with the column?
