The fuel pump is ran through the EFI circuit opening relay as well as the EFI Main Relay. The EFI circuit opening relay is located behind the right side of the dash, above the ECU. The main relay is located in the fuse / relay block #2 (on the front right corner of engine compartment).

Okay, we have no power to the circuit opening relay, no power to the fuel pump and no power to mass air. The coil is firing, spark plugs firing and fuses are good. What could the problem be? Could it be whats on top the coil? Thanks for the help:)

Here is a wiring diagram for the circuit, it looks like the fuseable links in the system are blown if the EFI fuses are all good

My truck dies out after being warmed up. I replaced everything (plugs, wires, fuel/air filter, and oil). On another note, is there a fuel pump relay switch and where is it located. Any help will be gladly appreciated. Thanks.
