Sounds like the air intake manifold gasket getting bad. Easy way to test this is when it is idling high, take a can of brake cleaner and spray it on the air intake, all around the gasket. If the gasket is bad, the car will change it's idle as the cleaner is sprayed on it. This happened to both of my 02 saturns. The air intake manifold gasket is located on the back side on the top of the motor. Very easy to get at and a very easy test. To locate it , look for the throttle cable on the throttle body. Look to the left of that and you will see the air intake. It's an aluminum manifold held on by 8 ten mm nuts. Right behind the fuel injectors. You can also use ether or quick start, and it wont take much. If the idle changes, you intake gasket is bad. Let me know how you make out

Your getting plenty of gas(black smoke). check vacuum lines, Make sure the intake air plenum is tight(hose clamps) check the MAF sensor. After the check the fuel pressure regulator. This will dump gas into the intake also. After that go for the injectors. Stuck open will cause this.

How many miles on it ? I recommend doing a compression test on that cylinder if you haven't already done it ! Before you replaced all those parts did you check for spark ?

You can tell a lot by the look of the spark plug , was it wet looking , fuel fouled Black ,carbon fouled , nice tan color , what ? How to Read Your Spark Plugs Davison Automotive

If your security lamp is flashing, 1st question is how does the ignition lock feel? GMs of that era use a system called PASSLOCK that senses proper undamaged rotation of the ignition lock cylinder. They do wear out and break, but not terribly often unless you can feel its loose and floppy or its been sticking and you have to wiggle the key lately to make it turn. If that sounds familiar, you may need to replace the lock cylinder. If the security lamp is on solid and doesnt go out, that mneans a fault has been detected and stored and you are best off having it scanned by a qualified technician or shop with proper scan equipment. If the lamp is flashing, your problem is mosty likely the key/sensor/cylinder are not signalling the body module, OR the body module may be failing. The cheap version of reprogramming without tools is as follows. Key off, rotate to on, wait a few seconds, turn to crank for a moment (less than 1 second) and then release key back to the run position. Note the status of the security lamp. It will either be flashing, or ON SOLID if a security problem is recorded and preventing start. WAIT 10 minutes and then stare in again at the security light. If it is still doing the same thing as before, you must wait 30 minutes total and recheck the light. If it changes in 10 minutes (Some cars it will, usually not unless using a scantool to speed the process), then you should be able to start the car now. If the light hadnt changed what it was doing and is still ON or FLASHING, wait 30 minutes exactly, no more than 35 (counted). Check the light again. When program learn is complete the light will turn OFF and stay off. Rotate key back to start and vehicle should start IF key/security was your issue and no other hard faults exist (Such as failed sensor or defective BCM). Hope it helps.

You must be havin a greenish white deposit on one of your battery terminals. It is called anode mud. just pop the hood and clean off the anode mud and then tighten the terminals. You car should start fine now.
