The Best Tests For Fuel Delivery Systems
The ancient Greek philosopher Heraclitus said that there is nothing permanent except change. Greek history aside, it’s easy to spot change in our current market because vehicle fuel delivery technology has evolved to include conventional, pulse-modulated and direct fuel injection fuel delivery systems, with each having a specific set of components and testing issues.

Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or mass air flow (MAF) sensor to address a P0171/P0174 “lean-condition” DTC with no result. In all likelihood, the technician didn’t consider the possibility that the vehicle’s fuel might be contaminated with E85 gasoline, diesel fuel, stale gasoline, or, to a lesser degree, sugar and water.
Diagnostic Solutions: Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Import Specialist Contributor Gary Goms discusses how contaminated fuel can mimic the symptoms produced by defective fuel pumps, fuel injectors and fuel control components like mass air flow (MAF) sensors. Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or MAF sensor to address a P0171/P0174 “lean-condition” DTC with no result.
Diagnostic Solutions: Testing Fuel Delivery Systems – Checking the Basics First Can Facilitate Diagnostic Strategy
Vehicle fuel delivery technology has evolved to include conventional, pulse-modulated and direct fuel injection systems, with each having a specific set of components and testing issues. Gary Goms explains how to avoid some of the most common mistakes in diagnosing fuel delivery systems.

Tech Feature: Preventive Maintenance Should Include Checking the TPMS
Among several things, winter always drops unpleasant reminders of the many issues that can affect automobile and tire performance for the rest of the year. Tire pressure monitoring systems are just one of the more recent components whose operation can be adversely affected by winter’s wrath. As is common, these issues last well into spring and sometimes are 12-month-long concerns for drivers – and opportunities for tire dealers.
Tech Tip: ‘Simple’ Tire Rotations with TPMS Can Prove Tricky
Bias. Everyone, whether it is politics, labor, religion, food, whatever, has a bias. Mine is government overregulation in the name of safety. It is with that built-in opinion that I will attempt to explain what tiremakers, TPMS tool manufacturers and sensor makers want you to know about tire rotation and TPMS. The other day my left rear tire went down in an instant thanks to a ….
Tire Tech Tip: Selling Nitrogen can Pump up Profits
For the past five or so years, suppliers of nitrogen-inflation equipment have made serious claims. Compared to moisture- and dirt-laden compressed air, nitrogen – a dry, inert gas – runs cooler, does not permeate through rubber as quickly and does not cause rust to develop on steel cords, expensive wheels or tire pressure monitoring sensors. The result is better fuel economy, more consistent inflation pressure, longer tire life and increased safety, advocates say.
Tech Tip: Top-Notch Design is Key When Selecting New Filters
Veteran auto mechanics will remember the days of oil-bath air filters, cartridge-type oil filters and sediment-bowl fuel filters. While these early-design filters would work well under a narrow range of circumstances, most were woefully inefficient and inadequate in the long term. All were subject to careless installation and dirt contamination during servicing.
