Question about 1990 Buick Century
1990 buick has alot of problems with sensors. could it be mass air flow sensor, fuel reg,or Map sensor.
Sorry this vehicle does not have a fuel shut off switch or inertia switch > that's ford ! If you pour fuel in the throttle body an it runs It's something with the fuel system , an if you replaced the pump an filter an regulator , It has to be electrical ! did you check voltage at the fuel pump relay ? What engine does yours have , 2.5 , 3.3 L ? There is a in line fuse for the fuel pump near the relay ! There are four relays front right of engine compartment mounted on radiator support cross member . The one for fuel pump is the one on the inside . Fuse is near there an there is a connector not connected to anything ,this is for fuel pump prime . Jump battery voltage to it a see if it runs then ! or replace relay !

It is most likely caused by the fuel pump shut off or inertia switch located most likely in the trunk on the drivers side beside the trunk hinge if not there in the passenger side floorboard next to the kick panel where the right foot would sit. this is a switch installed by the factory in case of an accident it shuts off the fuel pump
