Question about Cars & Trucks
NOTE! WHILE THIS IS NOT A HARD REPAIR, YOU ARE DEALING WITH GASOLINE AND GAS VAPOURS. tAKE THE NECESSARY PRECAUTIONS.
Take out the back seat (there are 2 pull-tabs to release it and it will lift up) and you will see 2 square plates that are screwed down. Remove the one on the passenger's side and you will see the the top of the gas tank and the sending unit (the sending unit contains the fuel pump).
Remove the electrical connector on the sending unit, and then start the car. It should die immediatly. Try starting the car several time to relieve the fuel pressure.
Next, remove the negative battery cable for safety. Then remove the 2 hoses going to the sending unit. One is held on by a hose clamp while the other is a threaded fitting. I REMOVED THE RUBBER HOSE FIRST AND ALLOWED THE GAS TO LEAK INTO A CONTAINER UNDER THE FUEL TANK.
AFTER TRYING TO UNSCREW THE METAL HOSE COUPLING, I REALIZED THAT THE RUBBER HOSE CONNECTED TO THE THEREADED FITTING WAS TWISTING INTO A KNOT. ( THE FITTING ON THE SENDING UNIT DOES NOT TURN_YOU CAN RUIN THE SENDING UNIT BY TRYING TO TURN THE FITTING ATTACHED TO THE SENDING UNIT. )
I HAD TO JACK THE VEHICLE UP, PLACE JACK STANDS UNDER THE REAR WHEELS, AND UNSCREW THE OTHER END OF THE THEREADED FITTING FROM THE SENDING UNIT WHERE IT CONNECTS TO THE FUEL LINE UNDERNEATH THE VEHICLE. YOU WILL HAVE TO TURN THE FUEL LINE FITTING TO DISCONNECT IT FROM THE LINE THAT ATTACHES TO THE SENDING UNIT. AT THIS POINT, YOU WILL BE ABLE TO UNSCREW THE THEREADED FITTING THAT GOES TO THE SENDING UNIT. IT IS SAFER TO UNDO BOTH ENDS OF THE THREADED FITTINGS AND REMOVE THE HOSE BEFORE YOU ATTEMPT TO REMOVE THE SENDING UNIT/FUEL PUMP ASSEMBLY.
Then remove the bolts on the sending unit and remove it from the gas tank.
Replace the pump in the sending unit and then put everything back together.

by chance the replacement pump you used was it a "CARTER" brand I had one of those quit the same day installed it! also be sure that the feed wire on pump in tank is connected properly! you can change them by taking out the back seat of car!! the seat has 2 clips good luck

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

I know you said new fuel pump and filter but I would recheck the fuel pressure. Drive the vehicle with the fuel pressure gauge on it and see if the pressure drops after 10 minutes.
