On the relay, 30 is powered by a fuse from the fuse block. It is shown in the diagram I sent. 30 is for the load side.
The control side ground comes from the PCM. When the key is turned on, it will power pin 85. Then after two seconds, it will shut off. It will send constant voltage cranking and running.
Here are the engine and fuel pump wiring diagrams so you can see how the system works.
Check out the diagrams (Below). Please let us know what happens.
