No, they do not, the fuel pump ground is under the rear seat while the ECM ground is under the dash on the left side here are the engine wiring diagrams so you can see what I am talking about and how the system works.

This guide can help you check the wiring as well:

Sorry yes it does, the PCM closes the ground, does the valve have power with the key on? If not check the injector fuse 15 amp. Here is a guide to help:

and the fuse location in the diagrams below. Check out the diagrams (below). Please let us know what happens.
