Good question. There are certain things an engine needs to start and run.
> air-fuel mixture
> volumetric efficiency
> compression
> ignition

Which of these things is your engine missing?

Nobody can tell you over the internet without first checking the vehicle out to determine which of these things are missing. Even if we knew which one, there are MANY things that can be the possible cause of each of these things to not be correct.

Plain and simple, the vehicle is going to have to get checked out.

Anybody who tries to tell you any different does not know anything about automotive diagnosis and repair.

Bought it and drove it home. next day started it, died, and wont start. Changed cap, rotor, plugs, wires, fuel filter. and last night fuel pump. running out of ideas

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.

Girlfriend's 2002 Yukon will crank but then occasionally RPM's will drop and it will almost die. Replaced O2 sensors but ... still occurring?

Look at the mass air sensor next to the air filter, check to make sure the clamps are tightend and it is properly sealed. Quick oil change places ar famous for not putting it all back together properly after checking the air cleaner.
