Question about Cars & Trucks
Who is doing this work ?
Can not see the relays needing to be replaced
Did you even test them,if not why replace them?
Why the fuel pump?
Was that tested or it just seized up mechanically
or stopped electrically?
Before you can continue, you need a wiring diagram,
to learn the fuel pump circuit
When you have that down,you will have picked test
points for your volt meter & live voltage drop tests, as
well as ground side testing
You will also see on the print what else in the vehicles
systems, may have to be complete, in order for the fuel
pump relay to come on
You can power the pump direct from the relay socket,
if you read the wiring diagram & have no other wiring
problems from there to the pump & ground

I have a silhouette and it had the same problem
Follow the fuel pump wiring harness to where it plugs into the floor of the van--pull the connectors apart--they will probably be corroded, and you will possibly have to change both wiring harnesses or connectors.

The relay and fuse is located under the hood in the relay box. It will be labeled on the lid. If fuse is good, then test the relay. Pull it out and with a test light see if there is power. If there is then remember that one. Have some one turn the key on and find another power wire. There should be 2 powers.If there is only one power then there maybe a problem in the ignition switch. If there is 2 powers then you need to get to the top of the fuel tank and see if power is getting to the pump. The power at the pump will be there for only a few seconds once the key is turned on and then will drop off. Let us know how it goes.
