2014 Corvette LT1: The Engine Under the Hood

The art and science behind its combustion system makes the Corvette LT1 one of the most advanced V8 engines in the world.

Ford Tech Tip: Cackling Powerstroke Injector

Some Ford diesel vehicles with the 7.3L engine may experience a misfire or “cackle.” The injectors in the 7.3L diesel run off of the high-pressure engine oil pump.The #8 injector is the farthest away from the oil pump, causing a filling problem, which may result in a misfire. Ford replaced the #8 injector in some vehicles as needed with a different injector to solve the problem.

Tech Feature: Diagnosing Diesel Injector Problems

Injectors can fail in ways other than becoming just worn out or tired. Diesel guru Bob McDonald discusses common and not so common injector fails.

Diagnostic Dilemmas: Multiple Failure Diagnostics On High Mileage Engines

Gary Goms explains that in tough economic times, a driver has no way of knowing how many maintenance-based and component-based failures will accumulate before he or she can afford to have a technician investigate the problem once a Check Engine light comes on.

Maximizing Current Ramping Techniques In The Shop

Although modern on-board diagnostic systems are becoming far more comprehensive than in years past, it’s still important to know how to use a lab scope and inductive current probe to analyze the amperage flow through the primary ignition and fuel pump circuits.

Tech Tip: Audi Has MIL On with Multiple Low Fuel Pressure DTCs

Due to fuel intrusion into the low-pressure system fuel pressure sensor (G410), a false signal may be sent to the controller, resulting in a reading that is out of tolerance.

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.

Returning Engine Power Through Fuel Injection Service

Over time, fuel injectors will become flow restricted from both the deposits that the gasoline leaves in them as it flows through the injectors and the carbon deposits that form on the head of the injectors, causing engine driveability issues

Tech Talk – Engine Innovations to Reach Government Fuel Standards

In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.

Getting Stoked to Service the 6.0L Power Stroke

If there were one engine that plagues the mid-size diesel world, you would have to say that it is the 6.0L Power Stroke. The 6.0L came into existence because the EPA demanded tighter emissions laws for diesel engines. Even though the 7.3L was branded as the reliable workhorse for Ford, it would never be able to pass the tighter emissions laws that were going to come into effect for 2004.

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.
