Is there anywhere I can get a wiring diagram for the fuel system on the car listed above? I have replace both the fuel pump and fuel pump relay, but I cannot get any power top the fuel pump. The fuse is good.

Are you checking for voltage to the fuel pump while cranking the engine? Have you checked for spark and fuel pressure? Have you had the diagnostic fault codes read and recorded?

I am checking the green wire at the fuel pump. I have continuity from that wire on the relay and the fuel pump. I have spark, it is trying to start. There just is not any fuel. That is why I am trying to find a wiring diagram.

You didn't say if you're cranking the engine when checking for 12 volts at the fuel pump. If you aren't cranking the engine, you had better not have voltage there. The fastest way to tell if the wiring is okay is to bypass the fuel pump relay. If you know which terminals in the socket are for the relay's contacts, you can remove the relay, then use a stretched-out paper clip to jump those two terminals. When you don't know which two to jump, it's easier to pop the cover off the relay, reinstall it that way, then squeeze the movable contact. On most cars the ignition switch doesn't even have to be on to do that.

For the wiring diagram, there's nothing better than a paper copy of the manufacturer's service manual. Next is an online service manual. I use Mitchel On Demand, but it won't let me copy and paste diagrams; sorry. AllData is another online manual company that you can buy a subscription from for just your car.

My diagram shows a gray wire feeding the fuel pump motor. If there's a green wire, I suspect that might be for the fuel level sending unit, but I can't find that on the diagram.
