1999 Oldsmobile Intrigue

Engine Mechanical problem
1999 Oldsmobile Intrigue 6 cyl Front Wheel Drive Automatic 115000 miles

My car started shutting off while driving and sometimes would start back up but started getting worse. I climbed in the trunk and had a friend turn it over and listened, the fuel pump was not coming on. I replaced the pump and did the same and it is coming on now, it started for a few but then shut off and is acting the same. What else can I checked it just seems like it is not getting gas?

Check for spark and check for fuel pressure
if new fuel pump shutting off
check relay and oil pressure switch
