A code P1451 may mean that one or more of the following has happened: VPWR circuit open Damaged canister vent solenoid Canister vent solenoid circuit open or shorted to ground, power, etc. Damaged Powertrain Control Module (PCM)
Verify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage. When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal. Output test mode may be used to switch output on/off to verify function. Replace canister vent solenoid

TUNEUP? WHAT WAS CHANGED?NEED TO CHANGE WIRES,PLUGS CAP&ROTOR ELECTRIC COIL, CHANGE THE FUEL FILTER,IF STILL THE SAME?TAKE OUT THE FUEL FILTER IF WET THEN OK, BUT IF DRY THEN ,FUEL NOT GETTING TO THE ENGINE,CK WIRES TO AND FROM THE PUMP,STILL THE SAME THEN NEW PUMP

How to find the Security Keyless Keypad Code on the 1995-2001 Ford
Explorer or Mountaineer and how to use the Keypad functions. The factory
code is also printed on a label which is installed on the Remote
Anti-theft Personality (RAP) Module. This is the module that controls
the keyless entry system. It is
located in the left rear quarter behind the removable panel (see photo).
You will need to turn the two thumb screws counter clockwise and take
the plastic panel off to be able to see the unit. A flashlight may be
helpful in seeing the code. You are looking for the module and the 5
digit code on it like the one shown below.
Now that you’ve got the code I’ll tell you how to use the Keyless entry
and set-up your own code.Make sure when pressing the controls on the keyless entry keypad you press the
middle of the buttons to ensure good contact with the controls.
Check this for Programing the Keypad.
Hope this help (remember rated this comment).

Technical Description:
EVAP Control System Canister Vent Solenoid Circuit Malfunction
The EVAP system monitors the canister vent (CV) solenoid circuit for an electrical failure.
The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command.
Symptoms: You will likely not notice any drivability problems.
Causes: A code P1451 may mean that one or more of the following has happened:
*VPWR circuit open
*Damaged canister vent solenoid
*Canister vent solenoid circuit open or shorted to ground, power, etc.
*Damaged Powertrain Control Module (PCM)
*Possible SolutionsVerify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage
(PCM control side).With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage.
When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal.
Output test mode may be used to switch output on/off to verify function.
