I think my start problem has been isolated
So I heeded the advice of this forum and went to get my battery load tested this morning at my local auto parts store. The test came back fine and they recharged it for me as well. I reinstall the battery and tried to start the car, but again to no avail. So my next plan of action was to check the fuel pump. So I had my friend crawl underneath the car to listen if the fuel pump was priming while I start the car, and he didn't hear a thing. My suspicion is that the pump went bad, but I guess it could also be the fuel pump relay. What's odd is that there was no sign of it going out. The car has been driving fine and all of the sudden, it died. I will have my mechanic change it out (I do not like to play with flamable material, plus I have 1/2 tank of gas left in the tank) and see if that is the cause. If not, a new fuel pump won't hurt...
Well, at least I know my battery is still good!

The S-car fuel pump does NOT prime with just the ignition key on, the engine..
has to be cranking in order for the ECU to see a signal from the Cam Position Sensor. Only then will the ECU fire the fuel pump relay. As a result, a cranking engine that does not start could be due to a bad CPS (common enough at these ages), a bad FP relay (rare on this forum) or the fuel pump has failed (not uncommon and becoming increasingly more common).
I have advocated changing the fuel pump as precautionary preemptive proactive measure on all S-cars with more than 100,000 miles on the odometer.
