OK, here's the scoop! The car now runs again! Why? I donno! I was checking the fuel pump relay with a test light. I connected the clip to the neg. battery terminal and the probe I belive pin 1 on the relay. The relay clicked, and I could hear the sweet sound of fuel rushing up to the injectors. Now the car is back to starting normally. What did I do? I can not see how I completed a circuit, since i was using a test light. I needed pos. on one end and neg on the other to make the light go on. So what happened? And more importantly, what do I need to do to correct the situation, as I am sure this is only a temp fix.
