no power to fuel pump

Ok Guys, I have a 96 s10 p/u and I am getting power to the float but I am getting 0 power to the fuel pump...Can someone please let me know the fix on this one.The engine is the 4.3 vortec.fuel guage works but fuel pump doesnt....thanks to those who can help.

Check the fuel pump relay on the firewall.

Do you get the two seconds of hmming when you put the key to the ON position just before start?

I get no humming at all...pulled the pump and had it tested ...pump is working fine ..just not getting any power on the grey wire going to the pump...have power on the purple but not on the grey...is there an oil fuel switch that i can ck and if so where is it on my 96 truck ,,, and i know there are three relays in the glove box,,,which is the fuel pump relay ,,and should it be clicking when the key is turned to the on position,,,are there other relays i must ck?????????

I don't know which one it is so you be best talking to a mechanic about your year.

It should be clicking.

Sounds like you problem.

Check fuses and could possibly be the crash switch needs to be reset.

Since when did GM start using crash switches? I haven't see one yet. Any further info would be appreciated, always willing to learn.

Just went through this with my 01 Crewcab 4x4. I pulled the bed for easier access. In pulling the bed I disconnected a ground on the left
rear frame rail under the bed to disconnect the ground for the bed. This is also the ground for the fuel pump (Two different wires under the same bolt). My fuel gage worked, but not the pump, until I reconnected the ground. I was checking the connector for 12 volts using the ground in the connector but was getting 0 volts because the ground was off. Don't know if 96 is the same but its worth checking.

There is a fuel pump test wire on the fire wall (tan in color it is tucked away and not connected to anything.
Put 12 volts to it and see if the fuel pump runs if it does not run
It is a bad pump or a bad connector where the pump wires connect to the main wires back at the fuel tank. Have see a lot of the going bad
Fireplug

^^^What he said.

Hard to find the wire sometimes though.

the easiest way to determine if the pump works is to jump terminals 30 and 87 or 30 and 87a on the fuel pump relay. this will tell you if the relay is bad if you here the pump running. make sure you use a fused jumper wire. you dont want to create more problems.
