Looking for help with a 2007 Pilot 3.5l. Pump won’t run. Need wiring diagram. Can’t find the relay. Some say it is a 7 pin plug in relay and others say it is a 4 pin relay. Found 5 relays together near gas pedal. Only one I know for sure is the washer relay because it does work when I unplug it. Any help is appreciated. Thanks

 

I don't have that diagram but the FP relay is likely in the under hood box. If you find it you can test from there.
If not you can test the pump. Put 12 volts on the pump and see if it runs.

 

Fuel pump does run when you give it 12v & ground. I should have said that. Found relay it was under dash with 4 others. Has power at relay when key is on. My question is the red wire at pump is not getting power. Does the red& white wire from relay go directly to red wire on pump?

 

Swap that relay with another and see if it works.

 

update, ordered a diagram from ALLDATA. It shows the red& white wire from relay as the feed to the fuel pump. I can make connect a wire from red& white wire to red wire at pump and car runs fine. Can’t tell from diagrams if the wire goes directly to pump or does it go somewhere else first. If it doesn’t I must have a bad wire somewhere. Continuity test shows bad wire if it goes directly to pump wire.

 

Let's see the diagram. If you can't tell how it works you may not have enough experience with reading them or you have an incomplete diagram.
Did you test or swap the relay?

 

Relay was changed. Did notice it get hot when running. Trace feed wire to pump and while doing that it started working. Can’t get it to not work now. Played with wires in the same area that it started working from. Did determine that red/orange wire does go directly to pump.

 

The PCM sees the engine is cranking and it trips the relay to apply battery volts to that 'feed wire'. That's the entire circuit. You are talking about colors we can't see. Where's the diagram?

 

 

A11 is the pcm driver to apply volts to relay and turn on pump. This is a very simple circuit. You can test wiring with a light as a load. I would crank it and see if the PCM is making the green yellow wire hot. If not need to see why.
If PCM is triggering the relay and the relay is working do this.
Check that G601 is clean and tight and that C601 is good.
