Do this find the inertia switch behind left rear quarter panel near air suspension switch and test for power at the pink and black wire-No power have the integrated control module and the ECU tested. Have looked for the fuel pump relay couldn't find it-I believe its the IRCM that does the switching
Inertia switch
IRCM
The Integrated Relay Control Module (IRCM) interfaces with the Electronic Engine Control (EEC-IV) system to provide control of the cooling fan, Air Conditioning (A/C) clutch, and fuel pump. The module also contains the EEC power relay to provide power to the EEC-IV system, and the fuel pump relay to provide power to the fuel pump.
