Fuel Pump & Injector Service in Hillsboro, KS
The short answer
If your engine cranks a long time before it starts, sputters on the highway or loses power on a hill, a weak fuel pump or a clogged injector is a likely cause.
A pressure test tells us for sure. The pump sends gasoline from the tank to the engine, and the injectors spray it in as a fine mist. You might notice it pulling a loaded trailer up the grade on I-135 toward McPherson, when the truck suddenly bucks and falls on its face. We test each part in Hillsboro before recommending anything, for drivers across Marion, Harvey, McPherson, Chase and Lyon Counties, so bring it in, or we will come and get it.

Text us which onesWhat fuel pump and injector service at Moxie actually looks like
We test pressure before we replace parts. A fuel pump is often the part people replace first on a guess, and it is an expensive guess when the real fault was a relay, a filter or a sensor. Measuring pressure and volume tells us which it is.
We look at injectors one by one. A single clogged or leaking injector can make the whole engine run badly, and there is no need to pay for a full set when one has failed.
We explain it clearly and price it before any work starts. For diesel trucks, where injectors work very differently, see our diesel injector repair page.

What wears out fuel pumps and injectors around here
- A fuel pump wearing out with age, often sped up by running the tank near empty, since fuel helps keep the pump cool
- A clogged fuel filter making the pump work harder
- Dirt, dust or water in the fuel, which is easy to pick up from an old farm tank or a dusty fill
- Carbon deposits from lots of short trips clogging an injector so it sprays poorly or unevenly
- An injector sticking open and leaking fuel into the engine
- A wiring or relay fault cutting power to the pump or an injector
How we test the fuel pump and injectors
- We connect a gauge and measure fuel pressure and volume, both at idle and under load, because a weak pump can make enough pressure at idle and still starve the engine on the highway.
- We check power and ground to the pump before condemning it, since a bad relay or corroded connector can imitate a failed pump.
- We watch live engine data, such as fuel trims and misfire counts, to see which cylinder or bank is running lean or rich.
- We test each injector's electrical circuit and balance, so we replace only the injector that has failed.
- We check for fuel leaks and smells around the injectors and fuel lines.
What we check
- Fuel pressure and volume
- Fuel pump power, ground, relay and fuse
- Fuel filter, where your vehicle has a serviceable one
- Injector operation, balance and wiring
- Fuel lines and connections for leaks
- Live engine data and stored codes
What the repair usually is
- Fuel pump replacement, often as a complete assembly in the tank
- Fuel filter replacement
- Injector cleaning, where the injector is dirty but otherwise sound
- Replacing a leaking or failed injector
- Repairing a relay, fuse or wiring fault that is starving the pump

Fuel pump and injector questions we hear every week
How do I know if my fuel pump is going out?
The most common signs are longer cranking before the engine starts, sputtering or loss of power on the highway or up hills, and a whining noise from the fuel tank. A fuel pump can also fail suddenly with no warning. The only way to be sure is to measure fuel pressure, which is quick and saves you from replacing a pump that was fine.
Do fuel injector cleaners in a bottle work?
A good quality fuel system cleaner can help keep injectors clean and may improve a mildly dirty one. It will not fix an injector that is badly clogged, leaking or electrically failed. If the engine is misfiring or running rough, it is worth testing rather than trying bottle after bottle. Text us what it is doing and we will tell you honestly.
How much does it cost to replace a fuel pump?
The price depends mostly on your vehicle, because some pumps sit under a panel beneath the back seat and others need the fuel tank or truck bed removed first. The cost of the pump assembly also varies by make. Call us with your year, make and model, and after we confirm the pump has failed you will get a price before we start.
