Hyundai Fuel System And Emissions Diagnostics

Bob Dowie recently had a 2002 Elantra GLS in the shop. This vehicle is a good example of some common fuel trim and emissions problems you’ll see.

Fuel Pump Diagnostics: Using Scan Tools

The most common diagnostic procedures for fuel pumps in the past were analog and hands on. Most fuel pump-related problems could be solved with a pressure gauge and voltmeter. Today, the scan tool is the most important tool when diagnosing a fuel supply problem.

Servicing Saddle-Style Fuel Tanks

Automakers have installed saddle-style tanks on several car models for more than a decade. This style of tank uses two wells, one on either side of a driveshaft or exhaust system. This position optimizes luggage compartment capacity, fuel volume and crash safety. The behavior of the fuel wells, pumps and sending units are often misdiagnosed, leading to fuel pumps being replaced unnecessarily.

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 enough fuel for combustion at larger throttle openings, but may also introduce an uneven air/fuel charge distribution into the combustion chamber itself, which usually results in hard starting, hesitation and reduced power output.

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.

10 Signs A Fuel Injector Needs To Be Replaced

In the past 30 years, the fuel injector has moved from the intake manifold to the combustion chamber. During this evolution, injectors have become more precise in dispensing fuel. If this precision is thrown off by restrictions, electrical problems or fuel problems, it can cause driveability issues. These are the top 10 signs fuel injectors need service or replacement.
