Direct Injection Diagnostics: Taking Pressure Readings

Direct injection is becoming standard on more and more late-model vehicles. These systems can be a diagnostic challenge, but with the right foundation, problems can be solved profitably.

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.

Subaru Pulse-Width Modulated Fuel Pumps

I think it might have been a 2003 Subaru WRX, but it was parked in front of my local Subaru specialist’s shop after going on its fourth fuel pump replacement from other shops in less than six months. Both the Subaru specialist and I agreed that fuel pump failures on Subarus were relatively rare, so the previous repair shops had obviously overlooked some very important details.

Water Instead Of Gasoline: Bosch Water Injection Innovation Can Reduce Fuel Consumption By Up To 13 Percent

Like many of the technologies introduced in recent years, the idea of water injection isn’t new. Water injection is emerging as a possibility today due to the convergence of fuel economy requirements, the increased accessibility of direct injection technology and the need for more enrichment due to the heating caused by downsizing with turbocharging.

Avoid GDI Performance Loss With New BG GDI Fuel/Air Induction Service

Gasoline Direct Injection (GDI) engines are prone to early carbon buildup. Vehicle owners will notice a drop in power and performance, sometimes before the first oil change. BG introduces the new BG GDI Fuel/Air Induction Service, which will remove carbon from the entire GDI fuel system in under an hour, says the company. GDI engines

Fuel Injector Diagnostics

In the U.S., the quality of the fuel we put into our vehicles is very high. By the time it travels through the fill neck, it has been filtered twice at the station. Before it gets to the fuel rail, it has been filtered by a sock in the tank and a filter under the car. So why do fuel injectors still become clogged or have spray pattern problems? The answer involves a little bit of chemistry and a lot of heat.

Direct Injection And Carbon Deposits

In 1985, Saab began using the new Bosch LH fuel injection system, and Volvo and other carmakers followed suit. The system worked such that incoming air passed through an airflow meter that sent a signal to the engine ECU telling it how much air was going into the engine. The coolant temp sensor then told the ECU how cold or warm the ­engine was, and it opened and closed the injectors when needed.
