1995 Oldsmobile Aurora Won't Start...replaced fuel pump and

I have a 1995 Aurora. About three weeks ago, out of the blue, it just wouldn't start. I had driven it to the grocery store and when I got back to the car it wouldn't start.
I had just had the fueld pump replaced 3 years ago but I went ahead and replaced it again...still wouldn't start. I changed the fuel filter...still wouldn't start. I check all the fuses and relays...but nothing.
After checking all the fuel lines I found that the engine is getting fuel. It seems as though something is preventing the plugs from sparking allowing the engine to start. Again...I checked all the fuses and relays...
What am I missing?

Thank you
