I took the lines of at the top of the throttbudy and getting fuel we pour gas in the carb it will run 4 a few sec
The object on top of the intake is the throttle body. Are you getting power to the injectors, and a ground signal from the engine computer ? ?

I agree with emissionwiz, pump may be making noise but I suspect little or no pressure getting produced. Would take a shop 10 min. to attach fuel pressure gauge & confirm.
SOURCE: will start when you put gas in carb but will not run (has new pump and filter)
Check all the wire connection on the throttle body, the throttle position sensor may not be sending the proper signals to the ECM which controls the fuel injector. Here is a link to retrieving the DTC codes which i hope can help you get your serra running again.
Good luck and hope this helps.

you need to see if the plugs are getting fire from the wires.

THIS IS A EVER SO COMMON PROBLEM ON THESE VEHICLES. THE FUEL PUMP HAS A BUILT IN CHECK VALVE WHICH IS SUPPOSED TO PREVENT THE FUEL FROM RETURNING TO TANK AFTER SITTING. WHEN THE FUEL RETURNS TO TANKYOU WILL EXPERIENCE AN EXTENDED CRANK TIME. THE PUMP COMES AS A COMPLETE UNIT ON THIS MODEL AND IS FAIRLY EXPENSIVE(250.00 OR SO) HOPE THIS HELPS AND DONT FORGET TO REPLACE INLINE FUEL FILTER AS WELL!!
Testimonial: "thank you D... so once it's running the pump works fine.. you think just the check valve therefore needing a new pump altogether..?"

remove fuel line from throttle body and have someone try to start. If no fuel is "shooting" out of line, there is a block. clean out line or replace.
