Question about 2000 Pontiac Montana
-battery is new, alternator checked with multimeter works fine. - turn key off after use kills all power to vehicle and wont start again, not even try to turn over, also heat and A/C not working related? - checked all fuses and connections inside cabin and under hood all good and dry. -Starter solenoid connections are good and clean. No idea, someone mentioned to me about the key lock cylinder, thinking back I have had some very minor problems with the key where I need to wiggle the key in and out to find the sweet spot for it to start, or I need to take key out and flip over and put in that way. Need help 3 kids need my van back ASAP, dont have time to tear everything apart to figure it out!
I suspect an ignition switch problem, you need to check to see if when you try to start it if there is power to the signal wire at the starter. If there isn't, check the same wire at the ignition switch, if there still is no power, check to make sure the grounds from the firewall are secure and they have near zero resistance between the firewall and the negative battery post. Check to make sure there is power getting to the ignition switch, if there is none, then you have a broken fusible link under the hood

SOURCE: 2000 Pontiac Sunfire wont start
Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.

SOURCE: Pontiac Montana starting problem
All 4 power wires go together on the large center stud on the solenoid.
The purple wire goes on the small stud.
The purple wire supplys the trigger signal when the key is turned to the start position.Since your solenoid is clicking when the key is turned to start this is working properly.
I would check battery connections and then check power connections on solenoid again.Make sure all connections are clean and tight.

If you have a front wheel drive and not a AWD montana, it could be a bad wheel bearing or a brake shoe that may have broken loose.
Most likely it's going to be a bad rear wheel bearing and it takes less then 2 hours to replace. You can pick up the wheel bearing at Auto Zone or Parts Source for around $170.00 and they have all the instructions for you to do thew job your self if you like.
Tool's you will need: Jack Stand Ratchet with a 1/2 socket and extention Large screw driver 5 pound hammer Lock tight
To check if it is your bearing, try shaking the van from Side to side from the wheel. Listen and feel for any play, the bearing it self is sealed and the bearing my have gone dry.
Good luck and hope this helps. Oh you do not have to remove the brakes to do this job and use the screw driver from the top to split the bearing from the brake housing after you hammer it free from the Axle.

Starter solenoid , or wire that leads to it.
Also , if standard transmission , may be the switch on clutch pedal is intermitant.
Engine won't turn over unless it thinks you have your foot on the clutch.

On your van the solenoid is attached to the starter. If you can get a solenoid separate (i don't know if you can) then you will need to take the starter off and remove the solenoid (2 screws holding it on) and the wires (on red and one black i believe) pay attention to which wire goes where because you don't want to reverse it on the new solenoid.
