Fuel pump failure on the 2003 Chevrolet Silverado
Only 6 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When fuel pump failure gets reported
There are 6 reports of fuel pump failure on the 2003 Chevrolet Silverado, 6 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 85,000 miles. It is the 30th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 45,389 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $600–$2,600 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 12 model years of this car. It shows up earliest on the 2005, at a median of 900 miles, and latest on the 1998 at 130,000 miles.
By volume the 1997 carries the most reports, with 26; the 2003 has 6. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Fuel pump failure. With only 10266 miles on odometer, the fuel pump failed causing the vehicle to stall in heavy highway traffic. We were nearly hit by other vehicles numerous times before making it to a shoulder. *jb
I own a 2003 chevrolet silverado 1500 pickup truck. The fuel pump quit and had to be replaced, when the vehicle had just under 45,000 miles. The cost of the repairs amounted to $642, and was not covered under warranty. I have talked with 2 other owners of gm vehicles of this type and year and they have also experienced fuel pump failure. *jb
Anyone had their chevy truck fuel pump replaced? Apparently this is a default on lots of 2000 and later gm SUV's & trucks, a quick survey of people I know and their contacts has revealed that this is a common occurrence (4 confirmed). My 2003 truck (45k miles) is sitting in a dealership waiting for me to authorize +$1,000 in repairs (@10% of the value of the truck). There is a recall for tahoe's & suburbans etc. Regarding this issue. I want to escalate this issue and make it a recall item. A fuel pump that fails to deliver enough fuel to an engine will lean it out and eventually kill the motor, making this a larger financial and hazardous issue. Please let the NHTSA know if this has happened to you. If it happened to an associate of yours, please have them email the ntsb directly. On craigslist. *jb

How far this goes
This page is kept out of search results because 6 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 6 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does fuel pump failure happen on the 2003 Chevrolet Silverado?
Across 6 owner reports that included an odometer reading, half were filed by 45,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel pump failure on the 2003 Chevrolet Silverado?
6 reports have been filed with NHTSA, about 0.0 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
