Exclamation 93' century wont start...

hello guys i was working on my car this past week... i had replaced my fuel sending unit the old one had lines that were rusted through in so many places it wasnt even funny...

but before i replaced it my buick would start up fine. now it seems she isnt getting gas... i checked the lines and the pump is pumping fuel...

when i go to start, the engine turns over might start and sound normal but then just stalls almost like there is no gas in my tank...

i could use any help i can get i have no idea how to go about this atm...

thanks guys

replace filter? check ground and other electrical connections at the tank? sometimes disturbing the wires will make them intermittent.

you could have gotten a wrong or bad pump, ive never worked on one of those but there is normally a place on the rail to check the pressure. if its not in spec the engine wont start

i checked the fuel pressure and it was fine... i have moved on to suspect the vacum lines...
the rubber lines were rotted away... replaced them and got a big improvement... still stalling though... replaceing the fuel pressure regulator which required the removal of the injectors and fuel rails...
