Locate your starter and with the vehicle in park have an assistant hold the key in the crank position while with a test light you check for power at the posts on the starter solenoid. One post shoul have power from the battery, the other from the ignition switch and the other should supply power to the starter motor. Make sure your battery is in good shape and fully charged. If all you get is a click from the solenoid then it's likely that you need a starter. If no power fom battery check battery and positive cable/connection for integrity and tightness. The small post is power from the ignition switch if no power her with the key on the crank position check fuses, park/neutral safety switch and it's related wiring.

Thanks for the clarification. Engine needs 3 things to run. Compression , fuel , spark.
It's turning over so you have compression.
Check a couple of spark plug wires for spark.
If you got spark , most likely no fuel.

Was it running before the "tune up" ?

You may have corrosion inside your battery cables or a loose connection somewhere.

If you have a voltmeter connect one lead to the POSITIVE post of the battery and the other to the POSITIVE post on your starter while you have a friend crank the engine

This is called a voltage drop test and you should see less than 0.5v on the multimeter while you are trying to start it, if you have high resistance (corrosion bad connections) you will see a higher voltage. 0.5v is the MAX you should see.

Do the same test on the ground side of the circuit, connect to the NEGATIVE battery terminal and the starter case, your voltage reading should be 0.1v or less

that could be the rack and pinion leaking. as far as the noise goes, it is more than likely the same thing. have your local mechanic check it out because if its the power steering pump its cheaper to fix that than it will be to have the rack replaced.

Check the ignition switch, there is battery voltage to the fuel pump and ignition, because the engine starts with switch in the start position, now check the above with the switch in the run position, If there is no voltage replace the switch.

sensor 1 is the sensor located before the catalytic converter and bank 1 is the side of the engine with cylinder #1 so if i'm correct and you have a V-6 that would be the rear of the engine by firewall and the sensor would be in the exhaust manifold
