OLDS FUEL PUMP RELAY, WHICH
The fuel pump relay is the second relay up above from the fuses in this fuse box,if you locate where the fuses are in this fuse box you will see the second relay above these fuses is the fuel pump relay on this vehicle here.---------
Does the fuel pump fuse fuse #6 in the fuse panel with this relay have power across it with the key on.
The relay receives power from this fuse,it also receives a ground on one of the terminals from a chassis ground.---------
one of the other terminals feeds power to the fuel pump with the key switched on and with the engine running or being cranked over.the other terminal is the terminal that energizes this relay to feed power to the pump,this comes from the PCM(engine and transmission computer).
Most likely the signal from the computer isn't reaching or being sent to the relay to energize the relay to power the pump.------
In the relay there are 4 points.85,86,87 and 30:---
86 is constant ground.
87 is power feed in from fuel pump fuse should have power with key on.
30 is power feed to fuel pump when relay is energized.
85 is signal from PCM(from what I can tell this should be power when the key is switched on for the first two seconds,if no power then test for ground here for the first two seconds).
You can jump across from 87 to 30 to see if pump runs and if vehicle will start.
If the vehicle starts, then its faulty fuel pump relay, replace the relay, to order relay, click this link below :----

I need to know where
Although many Ford vehicles have a fuel pump inertia swtich that can be reset if tripped, there isn't a fuel reset button on this vehicle. Power for the fuel pump is supplied by a 20 amp fuse [#6 in the relay center I believe] and the power is routed through the fuel pump relay which is controlled by the Engine Control Module and then sent out to the pump. I rarely see a blown fuse or bad relay but do see a lot of pumps that wear out an quit working.
