Bravada Jimmy Fuel Pump 1996

The problem Im having is fuel pump on 96 Bravada. I get no fuel to engine? I put alittle in the throttle opening and it runs for a few seconds. I looked and think I found the red test wire on the drivers side wheel well and put it to the positive side of battery. Nothing. I saw on here that always doesnt work so I looked for the gray wire from the oil sending unit. Couldnt find the oil sending unit? Would you know where it is? Then I tried the swapping around of relays in the glove box. That didnt work. Would you know what relay it is? Theres 3. Would you know what fuse it might be also? I have been on here for hours looking up posts and cant seem to find exactly what I need to know. I hate to spend 240.00 for something it might not be. Oh another thing I have a FULL tank of gas and was wondering whats the best way to get it out?? Well I hate to be a pain with these questions but if you could steer me in the right way I would appreciate it so much. Thanks Rick

EMCB fuse.

The relay that has a orange feed wire and a gray fuel pump feed wire.

Find the gray wire to fuel pump and see if it ha 12 volts key on fuel pump 2 second prime or 12 volts engine cranking.

If so check your ground to fuel pump and for power and ground on fuel pump plug in.

If 12 volts and ground there fuel pump should run.

Let us know what you find there.

If tank is full and fuel pump does not run you may have to drop tank with it full.

No fuel to the engine? Is that a question? Or a definitive? Can you hear the pump power up the fuel rails? Do you know if there's pressure in the rails after the pump 'hums' up?

If it runs momentarily with gas in the TB bore, it's possibly a bad pump, but you do not know for sure until you check pressure, or have it checked for you...
