Its in the fuel tank

Do you hear the fuel pump come On for 2 seconds? if so check the fuel pressure if its within specs if not check fuel filter if its clogged if not-check the in tank pick-up sock if okay -then replace fuel pump.

See the guides below on testing the fuel pump

The fuel pump relay is located in the under-hood fuse box # 1.
