Yes to much of this.

Compressor is close to the shocks - Start with electrics - Find wiring and check for voltage at the compressor - compressor is small like the little ones you buy for tire pumping - like small -

Jumper a temporary wire from battery to compressor does that work? If not just replace the compressor. I've replaced mine twice for corrosion issues.

If pump works, look for leaks or leaking shock. You can use a tire pump to check shocks leaking.

Define - It attempts to turn over but won't catch and run ???? When you turn the key to start does the starter engage an spin the engine ? This would be a crank no start condition . If the starter doesn't engage an spin the engine this would be a no crank no start condition . Sorry to ask but i have only been an auto tech for thirty years an have heard a lot of different discriptions for these simple actions . crank no start or no crank no start . Very different diagnostic procedures . So when you turn the key to start , does the starter engage an spin the engine ,but won't start an run ?

Your vehicle security system has malfunctioned, you need to have it taken to the dealer for testing with a special tool called a "TECH2 scanner. There may be a service bulletin on this problem and you may be able to get help from GM on the repair.

Most GM products have the o-tube located inside the evap metal line where the high side hose connects. Evacuate the freon, then disconnect the high side line. Look in the metal line coming out of the evaporator and there it is. These can require that you carefully screw a screw into the plastic part then use vise grips to remove. Usually, these are replaced along with the filter/dryer when recharging the system.

This sounds like a case of clogged oil galleys. These are the passageways that allow the top end of the engine to pass the oil back to the oil pan/crankcase. Though it's an unusual case, this is sometimes caused by excessive engine sludge, gasket media or other foreign deposits lodged in the galleys, etc. If you're able to let the engine sit long enough to try and allow the oil to drain back into the oil pan, remove the valve cover, and look in and around the oil galleys for any deposits or foreign material. They are generally located on the outer skirts of the head. The only time I've ever seen a case like this was from a valve cover gasket that was replaced while leaving the old one inside the rocker panel (head.) Of course, you'll most likely want to replace the valve cover gasket again after this test. Also check to make sure the PCV valve isn't completely clogged either, while you're at it. It's of course a simple, cheap, and much-needed part of a vehicle's maintenance.

Let me know if you need anything else in your diagnosis. I'm here to help! :)
