You can check the inertia switch (fuel shut-off switch). Not exactly sure where it is but most likely it's behind the right kick panel or under the right side of dash at the carpet line where the passenger's feet would be. Just push down the button on top of switch to reset it. Good luck.

    There is also a switching valve that switches the tanks from one to the other. If the valve is bad neither tank will work, or just one tank will work. I have seen both ways in the past.

    You said that you checked for power with a test light. If power is present where you check it, it will only be there for 3 seconds and then shut off. You should have power there the whole time when cranking the engine. When you stop cranking the engine, power will shut off after 3 seconds. So have someone turn on key or crank the engine while you are under the van checking for power. Good luck. Hope this helps.

Why am I not getting any current from the fuel pump connector at the fuel tank, key switch on and test light grounded but no power at connector


The fuel pump only gets power when the engine is cranking over or it is running of course. Jumper the relay to test the line.

Why want my 93 ford ranger pick up start without pouring gas into the intake fuel pump want come on unless hot wired straight to batt


There is a fuel shut off switch (inertia fuel shut off-opens on impact) in the wiring between the fuel pump relay (in the under-hood fuse/relay box) and the gas tank. It may have opened. I don't know where it is located, it may be behind a kick panel under the dash. You may have to ask someone where it is.

The fuel pump fuse is a 20amp fuse, also in the engine compartment fuse/relay box. This fuse and it's wire is the power feed for the fuel pump relay.

Where is the fuel shut off switch located


Buick cars don't have them. From the fuel pump relay under the hood, the pump's power wire goes directly to the gas tank and the fuel pump connector.

If your pump is not turning on, check for power on the gray wire at the gas tank electrical connector while someone cranks the engine over. The pump wire, I think it is gray, should have battery voltage when the engine is cranking. If it does, you probably need a new fuel pump. Dropping the gas tank is no fun, it is a dirty job, not real difficult, just not a fun relaxing afternoon.

Shuts off while driving


The fuel pump gets power from the pump relay on startup, then from the oil pressure switch when the engine is running. You could try a jumper to the relay to bypass the pressure switch to confirm the problem. The design is to prevent a fire in a wreck.

Interesting.
You have something that is keeping the fuel pump relay engaged other than the computer. The computer is supposed to ground the relay.
Or the computer is acting up.
The only thing in the gas tank is the pump and the sending unit for the gauge. And the power for the gauge should be off with the key switch off.
You may need a shop manual or repair book to get the wiring diagrams needed to trace the pump circuits.

I check the power going back to the fuel pump but there is no power at the fuel pump


I am confused if you are checking the power back to the fuel pump ? how far back to the pump?
if you take some wire ( if you know what you are doing ) and jump the pump straight to the battery will it run ( watch electric polarity )
then you know if the pump is working or not.
All modern cars with electric fuel pumps have cut-off switches/ pressure switches.
if the engine failes to start the pump is shut off, if one of these switches or a fuse is bad the pump will not get power.
If the pump is in the gas tank, and you have power up to the tank but the pump will not run - you need a new pump.

No power to fuel pump


check the tan- lt green wire on the fuel relay that is located on the right fender, mine wasn't pushed in all the way, this wire shut down injectors and fuel pump, if you are looking for the shut off switch to reset the relay, it is on the passagers side floor board under the dash, gas two wires, orange and pink, I don't remember the color of the stripes, I removed this switch and wired them together without a problem
