It sounds like you have a grounding issue somewhere. Look up a fuse diagram for the cabin fuse panel. Start from there.

A consumer lawyer has suggested that General Motors Issue a RECALL on these vehicles. Air Bags Problem on the 2002 GMC ENVOY Car problem(s) with the 2002 GMC ENVOY. This database includes information received by NHTSA from consumers either directly or as recorded by the Vehicle Safety Hotline. This information may be used by NHTSA during the investigation process. You may file your own complaint by calling the NHTSA Monday-Friday 8am to 8pm at (888) 327-4236. You can also file a complaint online! Though it has not gotten to the point of them issuing a recall, This is from December, 2014! Hope this helps.

Common problem after the battery is unhooked or replaced. You'll get the same results if you turn the AC on also...Unhook the battery, clean your throttle body, with throttle body cleaner (Seafoam works good) with only a rag or plastic bristled brush, no metal as it will scratch it. I prefer to remove the throttle body (4 bolts) to clean both sides, you CAN reuse the hard plastic gasket. When finished, hook the battery back up and drive around for 15 min or so (with no defrost or AC on,everything off), for the computer to relearn the newly cleaned TB. Your problem will be solved for about $8 if you do it yourself.

U need to reset security system (pass lock II). Turn key to on right b4 cranking but don't start and let security light flash for about 10-12 mins until it stops and then turn key back off, repeat procedure two more times don't actually turn key far enough to start during first two 10-12 min cycles, third cycle though after flashing stops turn the rest of the way forward for it to start. This should then reset security and solve problem sometimes only takes two cycles to reset. Good luck, hope this is helpful & solves problem.

I don't see any need to go into a long story here

You have at least two problems that may not be
all that big a deal

I would flat bed it to a dealer or local repair shop

well have you determined where the air leak is coming from???? Get soapy water and locate, could just be a fitting loose and a snug with a wrench is all. If this vehicle has an air bag and it is leaking from a puncture or crack in the bag then it has to be replaced, but check air line and fittings with soapy (dish soap ) water first.

sound slike you may have unplugged or disconnected somethine else or the spark plug you put in is bad or inpropper gap

check the sensor of the airbag it might be loose or the light on the cluster

You will have to be very careful!!! There have been cases where the airbag lights come on because of an internal computer problem. If you go to your dealer, or maybe a local shop, they will have to hook it up to a computer to determine the problem. Not to get too excited, but some people have had the bag actually deploy, so I usually make that known to anyone I help with an airbag light. Hope all goes well, and please be safe.

It could be a few different things. Do you hear a clicking during turn over? Its most likely your starter motor. After time the magnets wear down, and the bendix gear will not extend out to your fly wheel. Its actually a very common problem. I hope thats it, becouse it gets more expensive after that. If you have the knowledge to pull the starter out yourself, which is pretty ez, you can take it to a auto parts store, and they will test it for free.
