I would check fuse #40f in the engine bay fuse panel here is a guide to help and I have included the engine and fuel pump wiring diagrams so you can see how the system works.

I haven't found the one under hood yet not sure there is one. The only fuse box I have found is in the glove box any help to find any other possible fuse location would be greatly appreciated. Also, the distribution like thing on top of battery has one of the metal clips detached. I wonder since its metal is it possibly supposed to attach and since it's not maybe that's why no start. I mean the rest is plastic why would those be metal if not for connection reasons. I've been told both no, that don't matter and yes maybe it does can anyone tell me why all the complicated stuff on top not just positive and negative terminals?
