Signs Your Navistar Injection Pump Needs Replacement

Spotting early symptoms helps you avoid breakdowns. Look for these warning signs on your Navistar diesel:

• Hard Starting: If your engine struggles to crank or takes longer than normal to fire up, your pump may be losing pressure.
• Excessive Smoke: Thick black or white smoke during takeoff or at steady throttle often means the pump is not delivering fuel correctly.
• Loss of Power: A sluggish response when towing or climbing hills usually points to a weak injection pump.
• Rough Idle: Surging or stalling at idle indicates uneven fuel flow.
• Drop in Fuel Economy: A sudden dip in miles per gallon without other issues suggests the pump is failing.

Keep Your Budget in Check – Buy Pumps by Condition

We sort our Navistar pumps into three categories, so you can match your purchase to your needs and budget.

Brand-New Navistar Injection Pumps

Choose a new pump if you want the longest life and worry-free operation. These units come straight from OEM-approved manufacturers and meet Navistar’s original specifications. Each new pump arrives factory-calibrated. These are deal for work trucks and heavy-duty fleets, you rely on every day.

Inspected and Rebuilt Navistar Pumps

Our rebuilt pumps come from certified remanufacturers. Technicians disassemble each unit, replace worn seals and components, then flow-test the pump at exact pressures. At Goldfarb, we validate every rebuilt pump in our shop before it goes on the shelf. Get nearly new performance at a lower price.

Lightly Used Navistar Pumps

If your engine is older or you need a quick repair, consider a lightly used pump. Each used unit undergoes a leak and pressure check to confirm that the spray pattern meets factory specifications. You'll see the exact mileage and condition notes on the listing. This option provides reliable fuel delivery at the most competitive price point.
