Top 10 2003 Ford Crown Victoria Questions & Answers

There should be black split tubeing from the head light. Untape and check the connections that have been spliced. Usually the police flasher was hooked up at that point. You may have to follow the wires back to find the break.

remove the door panel. be very careful and make sure you get all the screws out. Should be maybe 2 on the bottom half of the door, and 2 on the top half. one is right by the handle, which is the one i forgot the first time i took my door pannel off. carefully pull the panel upward, and outward at the same time. Once the panel is off, disconnect the controls, and remove the light from the panel. Remove the plastic cover very carefully, it will tear, just keeps noise, and air, and the elements out.
There will be 3 screws, they are torx bolts, once you pull those 3 out. They are located middle of the door towards the right side. The motor will drop down a little bit. disconnect the wires for the motor, and wiggle the motor off of the regulator. the crown vics have a decent size hole to get into the door panel, you can also remove the speaker if that would help you do it. other than that, it just lining up the new motor into the car, pushing it into the regulator, and putting the 3 bolts in, make sure they are snug, and not cross threaded. put everything back together, and your set.

pull the b pillar cover off next to the driver's seat, there will be a connector with 2 red wires mounted to the b pillar right next to the seat belt retractor, find the other connector, and connect them. should operate normally.

There is both a fuse and a relay for the fuel pumps electrical system. The image below of the Power Distribution Box is located in the engine compartment.

Dear cdkkks,

Replacing a fuel pump in modern cars requires some preliminary electrical, fuel test analysis work. I have noted some professionals indicating you need to run car until gas lines, tank is empty; more than likely, if your fuel pump is defective, you cannot start the car, car is unoperative; you will attempt to start car, starter will turn the engine over rapidly without starting, let's assume you are in this condition.

First we need to test the fuses and fuel pump relay, basically the electrical opportunities on your vehicle, the relay panel is on the fender well, driver side, lift the relay control assembly from the fuse center and press the tab on the end, push down and this will release relays from the cover. This relay control panel includes the PCM power relay (left side in original position) Fuel pump relay (Center) this is the relay you are concerned with and the Air Conditioning relay on (Right). If you have friends, or associates who have electrical equipment to test the fuel pump relay, utilize their help, some automotive shops will provide this service. Checking the relay circuit with a jumper wire, any scrap piece of wire, 16-18 gauge will do; as you are looking directly down at the relay opening, you will note an opening at the 6:00 and 12:00 clock positions, 6:00 is the positive, 12:00 is the neutral, volt meter set for volts will confirm. Open the gas cap from the fuel tank filler pipe, insert the jumper wire and carefully listen for a whirring sound. If there is no sound and you have confirm electrical pump fuses, fuel pump relay is working properly (Voltage is pressure, battery voltage and slightly less voltage at the relay circuit when ignition key is turned on) then we have couple more checks to perform before we replace fuel pump. Let's check the fuel rail pressure on your Ford Crown Vic, obtain a fuel compression gauge with a Ford Schrader valve adapter, check to verify that no fuel pressure exists. If "NO" fuel pressure exists, and we have confirmed the voltage integrity of relay/fuel pump circuit, then we are ready to remove fuel pump. Use a simple gas siphoning kits from your local auto parts outlets to safely remove all remaining gas from gas tank, use appropriate gas tanks to store fuel; safety is the key here, gas and gas fumes are extremely dangerous; use appropriate chemical/gas gloves when siphoning/handling gas.

(A) Park your Crown Vic, perferably in a garage, concrete floor and make sure there is enough room around the back of the vehicle for you to work and move tools around.

(B) Raise the back of your car using a floor jack and support it safely on wheel/jack stands; remember, the driver side rear wheel must be removed in order to remove the fuel tank filler pipe, place your wheel stand (supplement with 2 by material for proper height on frame,slightly forward of rear wheel); safety is the key issue here and I cannot overly emphasize this issue, heavy wheel stands should be supporting the right rear wheel and frame, slightly forward of rear wheel, driver side).

(C) Disconnect the fuel tank filler pipe and the fuel pump connector located above the cross member underneath the vehicle, you must remove the (3) screws on the topside (fuel tank fiiler pipe) and approximately (4) screws on the bottom side, and the (1) screw adapter plate where the fuel tank filler pipe is inserted into the gas tank, top of wheel opening, underneath the vehicle. After these connections are removed, push the fuel tank filler pipe further into the fuel tank, allowing you additional room to lower the filler pipe from it's current position, downward; once you have sufficient clearance, twist, turn left, slightly back and forth movements and carefully pull outward, removing the filler pipe from gas tank. Do not damage the rubber groment in gas tank as you remove the filler pipe. As a note, when you reinstall the filler pipe, insert small amount of vasoline on filler pipe end that is inserted into the gas tank to facilitate the installation process.

(D) Support the fuel tank with a jack and remove the nuts from the holding strap using a wrench or ratchet and socket. Move the strap away and slightly lower the fuel tank in order to disconnect the vapor tube from the tee connector on the right and the vapor line from the canister tube. Discard the fuel tank mounting studs and replace with new fuel tank mounting studs on the reinstallation process.

(E) Unplug the pressure transducer electrical connector located on the top rear corner of the fuel tank.

(F) Clean area around the mounting fuel pump mounting flange. Remove/disconnect the fuel lines attached to fuel pump mounting flange then remove the fuel pump mounting flange mounting bolts in a crisscross pattern.

(G) Lift the fuel pump assembly off the tank. Replace the new fuel pump in the assembly and install the assembly in the tank. Install the flange screws and torque to approximately 89 inch lbs using a crisscross pattern. If no torque wrench is available, tighten to a snug fit and stop.

(H) Afterwards, raise the fuel tank enough to attach fuel lines and vapor lines indicated above, item D. After connecting all lines, raise tank with floor jack to its original position "carefully" and utilize the new mounting bolts, securing straps in their original position and torque bolts to approximatlely 25-30 lbs torque.

(I) Install the fuel tank filler pipe per the aforementiond process reversed.

(J) Review your connections and then carefully lower the vehicle, use a gas container, input 4-5 gallows of gas and start the engine and check for leaks.

Wishing you the very best,

Check the wiring and plugs under the front seats, the PSA group cars are well known for the contacts to go intermittant and cause the airbag system to malfunction. They are fiddly to get to but unplug and scrape the little contacts in the pluggs and then if OK put a small cable tie around the plug and socket ti stop them working loose.

The surpinetine belt is slipping on the alternator. A high pitch squeal can sometimes also be heard, because rain water is making the worn belt slip. So replace the belt first. Other possibilities are the idler tensioner might be weak, or worst case is the alternator itself. Also check if your battery cable connections are clean and tightened, because the battery may not be getting a proper charge.

Here is the fuse panel digram for the '03 crown vic:
Try Replacing Location 1 (15 amp fuse ) or Location 2 (5 amp fuse).

Here is the information you needed. I hope it helps and good luck....

That flashing indicates fault code 51. Fault code 51 indicates a problem with the driver's seat belt circuit. The seat belt buckle has a switch in it to determine if the belt is buckled up when the seat is occupied [determined by a pressure sensor in the seat bottom]. The switch in the buckle is either bad or the wiring to the switch is either short or open circuited.
Use of a computer scan tool can help narrow down the problem. There are four different scan tool fault codes relating to code 51. They are B2432, B2433, B2434 & B2435. These codes will give you more defined information on the actual fault. Most common faults are either a bad switch in the seat belt buckle or damaged wiring to that switch. Damaged wiring is usually caused by the driver placing objects under the driver's seat, which damage the wiring coming out of the seat belt. It is also possible to have a bad seat belt computer [Restraints Control Module or RCM]. A bad RCM is not common. Check for damage to the seat belt wiring under the driver's seat. Best to remove the seat and lift up the carpeting to do this. If no physical damage or water corrosion damage is present, replace the seat belt. After repairs, disconnect the battery for 1 minute to clear the fault code from the RCM's memory.
