Sounds like a major fuse blown.
Any wiring disconnected or stripped near the pump ?
Have you checked the major fuses around the battery and underhood fuse box ?

Great news, you can program a 1994 Lincoln Town Car keyless entry remote yourself! Here are the steps:

NOTICE: You must have all remotes on hand when performing this procedure. Any remotes not used during this procedure will become inactive.
1. Turn ignition to RUN or ACC.
(Run is forward, just shy of starting car.)
2. Momentarily jump pins in programming connector located behind the glove box.
(The connector will have two pins inside of it, and it will not be plugged into anything. Jumping the pins means to make a connection between the metal inside the plug. You can do this by using any metal, a metal paperclip bent in the shape of a "U" usually works perfect.)
All doors will lock then unlock to confirm programming mode.
3. Press any button on first keyless remote. Door locks will cycle to confirm programming.
4. If programming a second keyless remote, press any button on second keyless remote. Door locks will cycle to confirm programming.
5. Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.

Use the key itself? Perhaps I'm not understanding the question.

This post has some solution for getting your keyless remotes working again: http://www.clublexus.com/forums/ls400/438728-remote-keyless-locking-system-not-working-anymore.html

Hello: To resynchronize the keyless entry close all doors, key out of ignition. Hold lock and unlock buttons till the doors (all) lock then unlock. If the transmitter still doesn't work you have other problems. Go to auto zone they can check your transmitter to see if it is working.

Step by Step Solution:
1. Check the battery in your Key Fob/Remote, Replace?
2. If after replacing battery and still does not work then may have lost programming, or bad keyless entry module.
3. May need to take to dealer to have programmed or keyless entry module replaced.

The 1997 to 2003 Dodge Caravan and Grand Caravan use a standard key and remote setup with a separate remote fob. However, the 2004 to 2009 Dodge Caravan and Grand Caravan use a combination key and remote on one device. To program a new keyless entry remote for the 1997 to 2003 Dodge Caravan, you must have at least one functional remote, which is required to enter synchronization mode. To program the combination key for the 2004 to 2009 Dodge Caravan, you must have two functional combination keys. If you do not, you'll need to see an authorized Dodge dealer for keyless entry programming assistance.


2004 to 2009 Caravan Programming Instructions

1. Insert one of your working combination keys into the ignition. Turn it to "On"; leave it in this position for about 10 seconds but no longer than 15 seconds. Turn it to "Off" and remove it.
   
2. Insert your second working combination key into the ignition within 15 seconds of removing the previous key. Turn it to "On". After 10 seconds, you'll hear a chime and the "Theft" light will begin to flash, entering synchronization mode. Turn the key to "Off" and remove it.
   
3. Insert the combination key you want to program. Turn it to "On." After 10 seconds, you'll hear a chime; then the "Theft" light will turn off. When the light turns off, the combination key--including the key and the remote--is programmed.
   
4. Repeat Step Three for each combination key you want to program. A total of eight can be programmed.

Hope this help (remember comment and rated).
