did you test the fuel pump cutoff switch? It isn't possible to relay is bad. If you have a multi meter I can help you test the vehicle? You can also swap the relay with a similar looking relay to see if it makes a difference?

Customer: replied 5 months ago.
Headed home now, purchased new relay, will contact in 15 min, I pulled the plastic off passenger floor board and check the cut off. It's good

Can you tell me the test for the cut off switch? The red plunger is down, is there power there when the
Customer: replied 5 months ago.
Key is on
Expert:  James replied 5 months ago.

When you turn the key on you need to have 12v on both sides. If you are only getting power on one side the switch is bad.

Customer: replied 5 months ago.
12v both sides of cut off switch
Customer: replied 5 months ago.
Still no power to fuel pump
Customer: replied 5 months ago.
Still there?
Expert:  James replied 5 months ago.
Do you have power to the inertia switch?
Customer: replied 5 months ago.
I think I figured it out, there are 3 plugs at the fuel pump, two go to the water sensor, 1 to power the pump. The water sensor should have I plug that has 12v and 1 that doesn't. I got the plug mixed up and had two plugs at the water sensor that were 12v and the power plug to the pump was 0v, the 0v plug should go on the opposite side of the water sensor ?
Expert:  James replied 5 months ago.
The original fuel pimps had 3 plugs. Fuel power, WIF, fuel heater. The backside of the pump which is either brown or black is the actual fuel pump itself. The one going in the side is the water in fuel sensor. If you did mix then up you won't have the fuel pump turning on you are correct.
