Question about 2002 GMC Envoy
If you do have a security lockout then nothing can be done till you get the code so we have a direction to go. I really dont see a relay as being the issue As far as being intermittant on cold starts I would suspect a starter if it eventually starts without having to charge the battery. Smack the starter hard a few times while someone tries to start the vehicle. Use a hammer. If it reacts then you will have a direction to go

Thanks for using FixYa. Hi
The check engine light is on because ECM (Control Module) detected a fault with your car's system. ECM has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. You'll need to get the codes checked from a nearby dealer/mechanic.
However, as you are facing surge issue, it can be due to bad plug, bad fuel injector or a bad egr valve. Please try to start it in both park and neutral. Please check the starter relay under the hood. Disconnect the battery while checking all these things. Also check that there is no corrosion on the cables of the batteries. If so, put some hot water with baking soda to clear the mess. Check the transmission. Check the spark plug wires, fuel pump, crank angle sensor, PCM (Power Control Module), spinning engine, theft system failure and ignition switch Also try to jump start it. Also see this link for reference please---

There are about a dozen things that turn the service engine soon light on. TAke it to auto zone and have them read the codes free.
lights beep 5 times is due to problem in airbag controlling lights.
Probel is correct about the airbag light problem, and Ayn, you did not buy one without airbags. There are multiple lights for the airbag system...each for a different purpose. The amber light with the key is for arming and disarming the passenger airbag ONLY. There should be another one just like it in the cluster (speedometer area). If not, that's the one that is burned out and causing the 5 tones to sound.
Here's a site that will explain everything you need to know about airbag lights and resetting the system.
This website gives you the procedure for diagnosing and resetting airbag lights. See if your car is listed here. Although it’s a pay site ($14.95/day), it’s a lot cheaper than going to the dealer
On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.
The flashing light on your car is telling the answer you need. On some vehicles, the light is flashing a two digit code. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.
Airbagsolutions.com has the fault code charts to tell you what is wrong and how to fix it!
Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) and some require a scan tool.
Check out these websites also for more info on airbag systems and the light.
Lastly, check your vehicle for recalls through this link also:
I hope this was helpful to you. My information comes from years of experience in these businesses.

--------- The service engine soon light means that you car's computer has recognized something amiss and has recorded a 'code' in it's memory. Any auto repair shop would be able to plug into your car's computer, retrieve the code and tell you what it says. For a modest fee. Not a good idea to ignore this. get the codes checked first.then replace the faulty part. ----- This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Intermittent starting is a sign of the switch being bad, even though you already replaced it. If you can get it started take it to a parts store and have them scan your computer and it will tell you what is going on. They typically do not charge for this.
Also, check the connection at the battery, make sure cables are all tight and the ground cable is good and tight. If the ground cable is loose you wont hear clicking or anything. If there is any corrossion on the battery take a wire brush and brush it off. Or, you can pour coke on the posts and then rinse it off with water.
