How long since a tune-up? Are there any applicable trouble codes? Some of the national brand auto stores will check codes free. Does it stall at idle or going down the highway? With extended crank, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and check fuel injector pulse. If injector pulse is missing when problem is ongoing, two things I think of, do you have an rpm signal and security system where applicable. The rpm signal comes from crank sensor. Intermittent problems can be a pain to track. Don't replace anything unless your testing points in that direction.

the anti-theft has activated and needs to be reset.

Go to a GM dealer with the VIN and proof of ownership and they will make you another key.

Don't go to the dealer, cause they are way expensive.  Call a couple of local locksmith shops to find the cheapest price.  Also, look on e-bay for the key and chip to save money and then all you gotta do is pay for the labor to have the locksmith program the thing for you.

Shell has had issues with contaminated fuel in the past cant recall what it was but it actually damaged the fuel pump. I hope thats not the issue here can get costly in some cases fuel pumps on GM are a whole assembly. DOes the gas gauge still read properly? This was a big tell with the contamination last time. Gauge would read empty even when full.

sounds like a loose connection somewhere

No clicks at all? Does it even crank over? Maybe you blew the fuse going to switch. Check all connections where the + side of the battery go to. Is there something corroded? Did you clean the terminals good when you put the battery in? Sometimes things will work that draw a light load, but when you try to crank it over it will lose connection. That is all the things I would try.

is the bulb blown?? remove and test for power in socket

Yes if your car is equipped for this to happen. Look at your headlight switch. If you have a setting for AUTO or something similar and you are switched to that setting, your lights should be on. If not you may have a problem with a blown fuse or bad head light. It may be that your car just isn't equipped with this feature. GOOD LUCK FRIEND.

Check for a bent wheel. Hitting a curb too hard will bend the wheel enough to cause the wobble.

Gray is aluminum. Excessive wear is taking place inside the transmission.

You have correctly trouble shot a plugged heater core. Install a back flush kit on the car. They can be had at an auto parts store. Get new anti freeze too.

You have a warped head now that leaks coolant into a cylinder. Take both heads off and have a machine shop grind them flat. New head gaskets and you're good to go. That's an over simplified explanation. hats a big job dismantling the engine. Replace the thermostat and flush the radiator too.
