key or ignition failure --vehicle not recognizing key so security has kicked in

Is the security light flashing? Did the light respond to your 3/10 attempts. Make sure the battery is fully charged then just try to start. Many times while changing the switch the door stays open add to that your attempts to start and the battery will have enough current to run the starter but nothing left for ignition and fuel injectors. I hope this helps. Take care.

Could have fouled plugs if the cat was clogged. All other things check out like fuel pressure, timing, sensors etc...?

was this a gradual drop in performance or sudden ? The later will mean something has blocked or broken and should be obvious. Gradual may mean many things that you need to provide more information on .

At the rear of the radio, as well as fuse box

for heavy machinery cars etc. luckily there are many websites that can help you repair for eg site like reliable-store is very active in this.. instant help, emails and all that's fantastic

Doesn't appear to be. But if you are crazy patient you could tuck a metal rod with a 90 degree bend in it like a crank handle and theoretically tuck it in behind one of the seat halves to try and catch the release strap, then twist it forward. Might need another bend in what will be your handle end so you can apply enough twisting force to it. A second pair of eyes will be helpful so you will know if the rod has hooked up and how far you need to go. A number of Monte forums have run into this wall without a solution so good luck with cracking it.

Your heat cold damper is not closing. Actuator could be sticking or bad. Or some of the foam has come loose on the damper seal. Have seen leaves in the system causing obstruction. The problem is most vehicles require dash removal to fix the problem.

The tune up should be part of the routine annual service - maybe the car hasn't been serviced or maybe it hasn't been serviced very well. I wouldn't describe a sputter as a misfire but undoubtedly some folk would - nothing is more confusing or misleading than the different terminology folk use to describe the same thing. If sputter is an accurate description it suggests momentary fuel starvation. I suggest you initially don't worry about what might be wrong with it. The car is probably ready for a grand birthday where just about everything is looked at, studied, cleaned and adjusted or replaced and generally poked and prodded by learned men and in the process the current problem might be cured. Considering your post it is the best starting point I can suggest.

This is a very common problem on GM vehicles. The security system is known to fail. Basically when you insert your key, the system checks for certain OHMS resistance. If the system cannot get the correct signal from the key, it assumes the key is incorrect and goes into SECURITY lockout mode. (prevents hotwiring) This has been happening with GM;s for a very long time. There are ways to bypass this now. Read through this page for info, solutions as well. http://www.diy-gm-security.com/

Do a back pressure test on the exhaust system , partially clogged catalytic converter ? Have a qualified repair shop hook up a professional scan tool an view engine data. 011 Fuel System Tests Fuel System Scan Data

difficult to answer ,suspect either alternator or battery or both ? would realy need to see car to know the problem .

Check your pulleys, belts and tensioner.. If the belt is slipping and the spring is not keeping it tight, or the pulley is not free wheeling like it should, it can cause a charging problem

check switch connections and wiring

need to narrow down to electrical or fuel management --when no start is fuel pump working ---has the ignition system been tested or starter when no start

Do you have a scan tool that you can see sensor data ? What are fuel trims showing ? Is the computer add fuel because of a lean condition ? Are the O2 sensors switching , do you know what that is ? Can a scan tool communicate with the pcm ? If so probably not a bad PCM .What are the IAC valve counts ? Can the PCM control the IAC valve ? Suggest you take it to a qualified repair shop that know's how to diagnose , an not just replace parts .

All you can do is remove the radio and have it repaired by a local approved GM radio repair shop.

If you have a light in the glove compartment that might be staying on. I would start pulling fuses one at a time until the clicking stops. Pull a fuse, still clicking, put it back and pull another. Repeat until you find the circuit causing the problem. That will narrow down where you need to look.

check the actuator motor on the heater it opens and closes the doors for the heater and ac.
