Jeep Fuel Problems Needn’t Be an Uphill Battle

The Jeep Grand Cherokee has been a dependable vehicle for many vehicle owners over the years. However, the SUV has had a few fuel system problem that has put Jeeps in repair shops. In this article, we’ll address some fuel system complaints that have plagued these vehicles.

Ford Water-in-Fuel Indicator Dampens Driver’s Spirit

Some 2003-’04 Ford F Super Duty/Excursion (vehicles with 6.0L Powerstroke engine built prior to Nov. 1, 2003) owners may complain of an illuminated water-in-fuel (WIF) lamp. The lamp does not turn off after water has been drained from the horizontal fuel conditioning module (HFCM).

Tech Feature: Diagnosing Repeat Fuel Pump Failures

During the past several years, I’ve encountered many vehicles that were running on their third or fourth new fuel pump in as many years. As with many repeat failures, the initial fuel pump installations were sloppy or a brand of fuel pump with a known high failure rate had been installed. In the remaining cases, an OE or aftermarket-equivalent fuel pump had been installed, but fuel tank contamination had been overlooked as a cause of the premature failure.

Tech Feature: Diagnosing Fuel Pumps and Injectors

One of the first questions that should always be answered when diagnosing a fuel-related complaint on a fuel-injected engine is, “What is the fuel pressure?” All too often, technicians assume fuel pressure is “good” without actually measuring it with a gauge. If the engine runs, they assume the injectors are getting adequate fuel pressure. If

Hose & Reels: Reeling It In

It is said that a chain is only as strong as its weakest link. This idea applies to many things in life. Air tools and equipment are no exception. Today’s pneumatic equipment is far superior in many ways to equipment made just a few years ago. There are lighter materials and better designs, resulting in

Diagnostic Solutions: Fuel System Pressure & Volume Checks

For maximum efficiency, modern import fuel injection systems require that fuel be delivered at a specified volume and pressure. Because the fuel injector’s job is to mix fuel with the intake air charge, it must produce a finely misted, conical spray pattern through the fuel injector nozzle. Lower-than-specified fuel pressures not only fail to provide

Fuel Pump Diagnostics

Electric fuel pumps are a vital part of any electronic fuel injection system because achieving an accurate air/fuel mixture ratio depends upon the fuel injector receiving adequate fuel pressure and volume. Because electric fuel pumps have moving parts that wear out, they also have a relatively predictable service life and, therefore, become a predictable profit
