Question about 2003 Lincoln LS
Below you will see some diagnostic procedures you can try, keep in if this fails you might have to consult your local dealer on the repair :
1. Electronically unlock the vehicle (i.e., using the transmitter, keypad or power lock switch on the door) prior to attempting to diagnose the vehicle via Service Tools or entering Remote Entry System Programming Mode. Most newer model year systems (2002 and beyond) require this action before function is operational. 2. If extreme poor range performance is experienced: a. DO NOT change batteries on Remote Entry transmitters (Range does not change as battery ages). b. DO NOT replace or reprogram Remote Entry transmitters (Range is determined primarily by the receiver) If only one of the transmitters experience poor range, but not all, then it is OK to replace the bad transmitter and reprogram ALL transmitters back to vehicle. c. Verify external antenna is connected (if applicable). d. Ensure the poor performance is not only in certain locations. Examples; by radio stations or TV transmitting towers, power generators, etc. e. Ensure no other aftermarket/dealer installed devices are mounted on vehicle (especially systems operating at same frequency, 315MHz). If aftermarket/dealer installed systems are present, disconnect them and check FMC OEM system for proper operation. f. Ensure poor performance is consistent in nature and not just from one approaching angle from or to the vehicle. g. Poor performance is most likely the cause of a remote entry receiver, not a remote entry transmitter issue. 3. If there are other functional issues with the Remote Entry system: a. First determine if the Remote Entry system is OEM or aftermarket (dealer installed systems with Ford Logo are still considered aftermarket). Please note this fact in repair claim. b. Ensure correct Remote Entry devices (transmitters, keypad) are used with vehicle. This can be verified via part number or RKE Job Aid which can be viewed from the PTS or QCdealer websites. Even if the part has a Ford Logo, ensure it is one pictured on the on Job Aid. If not listed on RKE Job Aid then it is an aftermarket or dealer installed device and should be diagnosed and binned accordingly. c. Ensure there are no aftermarket Systems on the vehicle. Examples: Remote Start, Perimeter Alarm, Charging Cell Phones. Charging Coolers, etc ) If so, please note this fact on repair claim for easy identification. Disconnect aftermarket system and check OEM system for normal operation. d. Continue with normal repair procedures. 4. If the RF device (transmitter or wireless keypad) requires a battery replacement there is NO need to reprogram the device back to the vehicle. 5. If any one button, yet not all buttons on the Remote Entry device operates, there is NO need to reprogram the device back to vehicle. Follow normal repair procedures for inoperative function. 6. Be aware that before entering Remote. Entry program mode: a. First electronically Unlock the vehicle. b. Have ALL RF devices (transmitter. wireless keypads) present at the time of entering procedure. Most Remote Entry systems only allow up to 4 devices. Thus. if these other RF devices (wireless keypads) are added, it should be noted that the number of locations to store extra transmitters will be reduced. Inform the customer of this. c. Ensure no other vehicles within 50 meters of a vehicle entering program mode are attempting to enter program mode also or are activating any RF functions (transmitters / wireless keypad). This could cause cross programming, mis-programming or loss of programmed transmitters/wireless keypads from memory. d. Recall that once the first RF device is programmed to the vehicle. ALL other devices stored in memory get erased using the manual key cycling method to enter program mode. If service tools are used to enter program mode (on vehicles equipped with feature), the technician has the opportunity to add just one transmitter/wireless keypad to memory without erasing all others e. Verify how many devices are actually stored in memory before entering this procedure. This can be accomplished via diagnostic tools. If you do not receive ALL devices that are currently programmed to vehicle from customer at time of repair, inform the customer that when the devices provided are reprogrammed to vehicle none of the other devices left at home will operate the vehicle any longer. They should be referred back to their Owner's Guides for the manual programming procedure to reprogram ALL their devices to the vehicle again on their own. This should eliminate repeat repairs in the future. f. If all Remote Entry devices are not provided at time of repair, entrance into program mode via service tools is preferred over the manual programming procedure (if equipped on vehicle). Diagnostic programming allows individual RF devices to be added or it can be used to replace specific devices currently in memory and does NOT have to erase ALL devices currently stored in memory which would render those left at home inoperative. g. Be aware of difficulty of cycling the ignition between OFF and RUN on some manual transmission vehicles due to the ignition lock feature. It may be easier (if applicable) to cycle the ignition from OFF to ACC, rather than RUN (example, older Crown Vic/Grand Marquis) 7. Be aware on older Model Year Town Car and Crown Vic/Grand Marquis Vehicles, there is a higher chance of inadvertently entering program mode by only cycling the ignition from OFF to RUN two times by accidentally bypassing OFF and going all they way to ACC. If the customers complain their door locks cycled intermittently or their transmitters no longer work, it could mean they entered program mode inadvertently at some time. Transmitters that no longer work with vehicle can be easily determined if they are still programmed to the vehicle via diagnostic tools (Function Mode).
11. Crown Vic/Grand Marquis vehicles do not have feedback implemented to mark the ending of transmitter programming, the ignition key must be turned to OFF and there must be a 10-20 second wait to get out of programming mode. If the recently programmed transmitter(s) is tested before this time out expires, it may not work and technician may think it did not program at all

Replay the fuel pump relay since the prime switch works for the gas to star this engine
