Tech Tip: DeLorean Fuel Pump Replacement
DeLorean owners and enthusiasts know to be wary, a car left sitting that long and havoc ensues with the sensitive fuel system of a 25-year-old DeLorean. In fact, any car, left sitting for a lengthy period of time will eventually encounter fuel problems. One specific problem to note would be the need for a new fuel pump. Cars left sitting, and even daily drivers, can fall victim to fuel pump failure. Over time, debris and contaminants build up in the fuel tank.
Diagnostic Solutions: Solving Insufficient Fuel Problems
Solving cranking, no-fuel or insufficient-fuel driveability problems on late-model imports can be challenging, especially if a technician doesn’t take into account the way that modern fuel systems operate. Some vehicles, for example, limit vehicle speed by deactivating fuel injectors. In some rare cases, a miscalculation in vehicle speed can cause an insufficient fuel condition.
Independent Research Shows E15 Poses Minimal Risk to Older Vehicles
The conclusion of the Ricardo study is that the adoption of E15 as the blend limit for standard US pump grades of gasoline should not adversely affect vehicles manufactured between 1994 and 2000.
Groups Form To Delay E15 Fuel
The groups contend that E15 could harm many types of vehicle engines, fuel systems and components, as well as the environment.
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
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
