Bad ECM or ECM relay.
The fuel pump works through the fuel pump relay which in turn works through the ECM relay. This does not answer the question of where these relays are and wich ones they are.
It's programmed into the engine ECM. You need to either replace the ECM, or have the existing one reflashed with new parameters.
ECM is located on drivers side, below the base of the windshield underneath the plenum. You have to remove plenum panel for access.
i do believe it is the ecm/computer
not sure of your question, but, the relay is mounted under or behind the engine computer or ecm.. you have to remove the ecm to find the relay. It is on the inside of the firewall in the middle behind the radio. Good luck
