Will it keep running if starter fluid is sprayed into a vac hose when it's started? If not it's a spark problem.
If it does keep running then it is lacking fuel.
Remember,the fuel pump runs off power from the oil pressure switch once you use up the fuel from the "prime cycle" when you first turn the key on.

Start by getting a multimeter with a current coil clamp. Put around one battery cable and measure current leaking out.

Even after two years, you could have a bad battery

Is this a 2.8L vin W? I saw a service bulletin that said, do not replace maf sensor for maf sensor code. You install a new mem-cal. The new memcal doesn't use the maf signal, but does use the mat. If the update had been done on your vehicle, there should be a decal under the hood to notify you about the update. They did this because of problems with the maf sensor, at the time.
Just to add, problems at higher rpms, check for a blockage of some kind, air--fuel--exhaust. Use a gage and check proper fuel pressure.

I would check the fuel pump. When you turn the car on (not start) do you hear the pump? Have someone turn the key and listen at the rear of the car, if not...fuel pump may be bad.

No.. if there was a leak big enough to lose all pressure you would see fuel running on the ground. There is supposed to be no air in the system.. so air would not come out of the valve.. just gas. Next check to see of the fuel pump is running. Possible that it is not. When you turn on the key the pump should run for about 2 seconds to charge the system. Than when the engine starts the pump will commence running.. This is controlled bu the fuel pump relay. Which is controlled by the computer. You should be able to hear it run.. you may have to remove the gas cap and listen at the gas fill point.You can jump the relay to check if the relay is bad.. They are pretty cheap.The fuel pump is in the gas tank.. hard to get at if it needs replacing. You have to drop the tank. If you do this remove all the fuel you can from the tank. This series of GM cars did have fuel pump problems. (REMOVE THE BATTERY CABLE IF YOU TRY TO REPLACE THE PUMP)
Next remove the Fuel filter (its under the car) blow through it to see if its clogged. Replace it weather it is clogged or not. If it is clogged it could kill the fuel pump because it would make it work too hard. If It is clogged and you replace it.. car might start.
If not its probably the fuel pump, They can run and still not pump fuel if they are bad.

Yes the pump could be the problem .blown head gaskets are also a possability

not really there is only a few inches space, and the pulley remove tool needs at min 6 inches. would think the only way you could remove it without removing engine is to drill hole in the side of the wheel cover side so its in line with the cam gear. but it would need a big hole. then weld a cover on afterwards.

What your doing when you touch the test light to that 3rd wire is actually closing the circuit and powering the fan, like the temperature controlled switch should be doing once the engine warms. That sending unit would be screwed into the cooling system where the water can touch it and most likely is in the radiator lower tank or bottom of radiator side tank. Find that sensor and test the wires for power when engine is hot and fan should be on. You could put a toggle switch on it to activate the fan until you get the proper sending unit/sensor.

Probably a T-50. Due to the use of Locktite on these bolts, an impact wrench will be required. Do not use Locktight when reinstalling these bolt. Just get them tight ( 1/2 in. drive ratchet)

Check the catalytic converter it is probably plugged and not allowing fuel into the cyl. due to putting back pressure on the engine. If possible pull the 02 sensor out of the exhaust ahead of the catalytic converter and if it is plugged you should have the car to run. It will run rough but if it starts it is the problem.
