No fuel pressure, can hear fuel pump engage

[increasinglyhumbled]

I want to fiddle with the fuel filter, but have gotten confused on this model. Where the inline filter should be, it looks more like an inline fuel pump. Is the only filter on this model the canister type further down the rail?

What other things should I be looking at?

If there is a wiring loom feeding it, it is a pump.

There are 4 items in this fuel system on the feed side.

1) In-tank pump, it is in the tank.

2) Fuel reservoir/screener, inline unit next to the transfer case. It is not a filter.

3) High-pressure rail pump. It is (usually) behind a shield and almost perfectly in line with the driver's seat.

4) Fuel filter, inline, where the frame begins to run upward again at the front. It may also be behind a shield that has two studs that face upward through the frame. If you open the hood and look down at the frame right below the brake master cylinder you should be able to find your filter.

Now, if you have zero fuel pressure but hear a pump engage with a hollow buzz the high pressure pump is dead. If you have zero pressure and hear a pump engage with an electric buzz the rail pump is working but running dry.

I would unhook the rear lines at the strainer and point them at a drain pan and turn the key on.

My bet is that the pump in the tank is dead. It is almost silent so if you can hear one turn on at all, the high pressure one is likely OK.

If this vehicle has been sitting for a while and has any stale gas in it, you should also pull the tank and see if the rubber hose that connects the fuel pump to the sending unit is still intact. My experience is that these come in contact with stale gas and turn into goo almost immediately, which results in zero fuel pressure.
