How can i run a hot wire to my fuel pump. I am sorry to ask a short question but thats my question. Ive been online trying to figure it out but still no luck. an ideas to help would be greatly appreciated thank you
SOURCE: I have a 1988 Ford F150 that won't start. If you
go to the listed link below, they have the ECM (computer) for your truck, u have to use the exact same part number.

Hey lets try this ! Locate your starter solenoid & look for a yellow wire marked with a "W" . That may be the fusible link for fuel pump. Let me know what you find.

I had the same issue on my '86 Bronco. Change the ECM(computer) and your problem will go away.

1.- For identify the right fuse, check your 2000-Ford-Excursion-Owners-Manual position 112, 20AMP (Maxi Fuse); details in the page 138 and next.

NOTE
A fuel line disconnect tool is needed for this procedure.
CAUTION
Fuel injection systems remain under pressure, even after the
engine has been turned OFF. The fuel system pressure must be relieved
before disconnecting any fuel lines. Failure to do so may result in fire
and/or personal injury.
Negative battery cable
Fuel lines from the fuel filter. Have a drain pan handy to catch
any residual fuel once the lines are separated.
Safety clip from the male hose
Install and push the fuel line disconnect tool into the female
fitting.
NOTE
Inspect the fuel lines for any damage after the fuel is finished
draining.
Male and female fittings from the filter
Fuel filter from the bracket and the retainer, if equipped. Note
the direction of the flow arrow so the replacement filter can be
installed correctly.

To install:
Fuel filter into the mounting bracket with the flow arrow pointing
in the correct direction
Fuel lines to the fuel filter. Align and push the male tube into
the female fitting until a click is heard. Pull on the fitting to ensure
that it is fully engaged, then install the safety clip.
NOTE
When the battery has been disconnected and reconnected, some
abnormal drive symptoms may occur while the Powertrain Control Module
(PCM) relearns its adaptive strategy. The vehicle may need to be driven
10 miles (16 km) or more to relearn the strategy.
Hope this helped.

The pump should have a fuse in the fuse block. You need to check for power in the fuse block and you need to check power to the pump relay.
Sometimes there is a fusible link to the Relay. If you check the connector terminals for power where the Relay plugs in, you can determine if the fusible link has blown. You could have already replaced the bad parts and now need to restore power to the Relay.
Engine Starts:
· Fuel Pump secondary circuit shorted to power
· Fuel pump relay contacts always closed
· Open in fuel pump monitor (FPM) circuit between ECU and connection to POWER TO PUMP circuit
· Heated Exhaust Gas Oxygen (HEGO) sensor shorted to power
· faulty ECU
Engine Does Not Start:
· Open inertia switch or inertia switch circuit
· Open in or between ECU and fuel pump (This includes open in fuel pump brushes/windings)
· faulty ground connection at fuel pump
The easiest way to check this circuit is to go to the fuel pump relay. If the relay clicks when the key is turned to the "RUN" position, then the inertia switch circuit is ok.
The Pink/Black wire starts from the fuel pump relay and goes two directions. One side goes back to the fuel pump. The other side is the fuel pump monitor circuit and goes to pin #8 at the ECU. This wire should only be hot for a second or two when the ignition is turned to the RUN position.
The fuel pump relay receives power on the Black/yellow wire. It comes from a fusible link at the power distribution center. This wire should be hot at all times.
If all the above is working as designed, them you probably have a bad fuel pump.
