1996 Chrysler Sebring car just died on me and wont start

Engine Performance problem
1996 Chrysler Sebring 6 cyl Two Wheel Drive Automatic

My car died on me at a stop light and I couldnt get it to start back up. I have been told that it may be either my fuel pump or my distributor. I was told how to check a valve around the engine to see if its my fuel pump but I looked around and couldnt find it. I was wondering if someone could tell me where that would be located. Also, if its my distributor, how would I go about checking to see if its that? I was going to tow it to the dealership and have them fix it, but they are WAY over charging to fix it ($370 for a fuel pump and $140 in labor, which at an auto parts store the fuel pump was approx $170).
