2003 Ford Expedition: fuel pump failure

Filed Mar 9, 2026 · Electrical · AR

My truck stopped working in November 2025. I was told I needed fuel pump and filter. I replaced those and still didn't crank. I was then told I needed a circuit box. Purchased a circuit box and had it put on. Got my truck back February 2026. March 08,2026, truck went out again. I kept my truck maintenance and don't understand what's going on with it. I was told it is a recall on electrical parts and engine coils and spark plugs.

My Ford Expedition started randomly stalling and it stalled in the highway. The engine just shut down in the middle of the highway and it was such a scary a life endangering experience. This total loss of power in the middle of the highway when vehicles are traveling at highway speeds can cause death very, very easily to the occupants of the Ford Expeditions suffering this defect. I have been reading in many forums ( I have included the link to one of many forums) this is a common defect [XXX] ) many have Ford Expedition owners have experienced and have been very concerned and shocked that there was not recall. The issue is that the R303 relay (non serviceable fuel pump relay) fails very commonly on Ford Expeditions. In my Ford Expedition, the relay was melted. The fuel pump relay fails and cuts all current going to the fuel pump causing the engine to stall. This is a life-threatening risk caused by a defective fuse box with a defective fuel pump relay (R303). There were no warnings, the Ford Expedition just stalled randomly.

This SUV stalled on the highway while driving in traffic. It was caused by a fault in the fuel pump or fuel pump relay. Please recall this vehicle.

Tl* the contact owns a 2003 ford expedition. The contact stated that the fuse box failed. While driving 85 MPH, the vehicle stalled without warning, the steering wheel seized, and the fuse box made a buzzing sound. The contact coasted the vehicle to the side of the road, reached under the dashboard, and pulled the relay fuse to stop the buzzing noise. The vehicle was towed to the contact's residence where an independent mechanic diagnosed that the fuel pump was burned. Another mechanic came also came to the contact's residence and informed her that the fuse relay and the fuse box needed to be replaced. The vehicle was not repaired. The contact called anderson ford (3900 clemson blvd, anderson, sc 29621, (864) 225-4151) and was provided with a quote. The contact stated that the failure recurred several times and the fuel pump/filter, 402 sensors, and fuse relays were replaced numerous times. The manufacturer was not made aware of the failures. The failure mileage was approximately 236,000. *dt

"takata recall" I was driving down the interstate at 65 MPH when my truck just cut off, had to have it towed in to the shop. Had fuel pump replace, 2 weeks later same problem.had to have it towed again fuse was replace. 3 weeks later I'm now having to have the fuse box replace. Ford motor company don't think this should be a recall issue. They just came out with the latest update fuse box in 2017.

Take a look: http://sparkys-answers.com/2011/03/2003-ford-expedition-no-run-no-fuel.html my father's car is registering a p0231 code. My mechanic was thinking it was the charging system. (no code was registered for a period of 2 months.) today, it pulled a p0231 code. Much to my surprise there seems to be factual things documented all over the internet. I am taking the car to cherokee auto tech. Vincent nguyen is a register sae tech with a mechanical enginering degree. He also discovered the ignition cylinder on my 2003 pontiac grand am before it was an issue... This car is not any different. During high periods of driving, the solder "heats up" and stalls the gas. When the car cools off, the solder solidifies and current capacity to the fuel pump resumes... The fuse is not protecting the trace. You have complaints on your website on this model also. Even youtube videos.... Https://www.youtube.com/watch?v=1brgvbetkek if it is true with my model, I will give you factual evidence that you need.

The engine stops running without warning. I was driving on the freeway at 70+ in heavy traffic. All of a sudden the engine shuts down. I put the vehicle in neutral and engaged the flashers. I tried to restart the vehicle while maneuvering to the side of the road avoiding multiple close calls. Once stopped, I put the vehicle in park and tried to restart. After a couple of minutes the car restarted. I took the vehicle to the autozone to see if there were any fault codes. One code indicated the fuel pump was an issue. They advised me that they have seen this before and directed me to go to the dealership. The dealership could not look at it immediately so I had my son pick me up with another vehicle. The following day they ran a diagnostics ($95 fee that was totally unnecessary since this is a well know failure) on the car and indicated that it was the faulty central junction fuse box located inside the vehicle on the passenger side near the feet. Pn 3l1z-14-a068-aa-a11 @$517. Installation costs $215. When I got home I searched the web and found that this is a common failure for this vehicle. The blogs and comments are of multiple near missed collisions among other things. This part failure happened on vehicles that were less than one year old. It can happen at anytime to any 2003 ford expedition. This part was redesigned for later ford expeditions because ford knew of the problem. If you contact any pick and pull salvage yard you will find that all of these central junction box (fuse boxes) are not available since everyone tries to replace them by themselves because of the high costs. Also, there are multiple companies that will repair the faulty part with a re-engineered circuit. Ford has since made a new part with a different pn / model number. This should have been a safety recall in the first year. It is very dangerous and lives are at stake.

The vehicle will randomly shut off at any speed, under any condition. Engine dies unexpectedly at highway speeds creating a panic to get out of the roadway. Power to steering and brakes are gone when the engine dies. Vehicle will restart after a couple minutes. The faulty part is the fuel pump relay. It is integral to the fuse box and cannot be changed without changing the entire fuse box. The fuse box is only available from a ford dealer for $485.20 parts only.
