Danger, Will Robinson! Intermittent Loss Of Power
This month’s Diagnostic Dilemma turns the page back to September 10, 2015 when I got a phone call from a local undercar shop inquiring if I had the tools to check the ECM connector pin fit on a 2012 Chevrolet Impala with the flex-fuel, 3.6L gasoline direct fuel injection engine. In response to an intermittent loss of power complaint, the shop had found a technical service bulletin (TSB) indicating that loose PCM connections can cause a loss of fuel pressure on the GDI engine’s high-pressure fuel rail and set codes P00C6 and P228C.
Buick Turbo 3.8 V6 History
Buick started playing with turbochargers in 1976 when it paced the Indianapolis 500 with a Century equipped with a special turbocharged 3.8L V6. The actual pace car needed the boost cranked up to 22 psi to keep pace with the field. It produced 300 hp while the commemorative edition only had a V8 with 165
TI Automotive 39/50 Dual Channel Single Stage Pumps
TI Automotive introduces a higher pressure version of its 39/50 Dual Channel Single Stage (DCSS) pumps. The DCSS 39/50 has been designed around the proven 39 mm armature (motor) that has been used for many years, and features a single impeller with two parallel rows of turbine blades. It is designed for engines with more than 500 HP and features a flow rate of 400 lph at 40 psi.
Detergents For Modern Vehicles
As a technician, it is hard to gauge a consumer’s gas-buying habits: Some owners may use a cell phone app to find the cheapest gas, while others habitually buy gas at one or two stations. No matter the type of customer, some in-tank fuel cleaners can help to alleviate fuel system and carbon buildup issues. Selling these fuel system cleaners in association with other maintenance services, like oil changes, is cheap insurance against cheap gas.
MINI Turbocharger Failure Caused By Oil Supply Line Blockage
Find out how to repair a MINI Cooper turbocharger failure caused by an oil supply line blockage. The symptoms are loss of performance and turbocharger noise.
Top 10 Fuel Pump Fails
10. Strainer Blocks Fuel-Level Sender A fuel pump inlet strainer may be installed that is interfering with the travel of the fuel-level sensor’s float arm, which causes an optimistic fuel level reading. Dented fuel tanks may also cause a false reading by pushing the fuel-level sensor and fuel pump inlet filter above the remaining fuel
Turbocharged Technology
Utilizing electronically controlled wastegates and bypass valves With the ability to increase fuel economy by up to 20% on gas vehicles and up to 40% on diesel vehicles, manufacturers have resorted to turbochargers to compensate for lowered engine displacement. Additionally, the improvements on turbocharging technology have increased the number of turbocharged vehicles on American roads.
Ultimate Underhood: From Mechanical Fuel Injection to Putters
Mechanical constant stream fuel injection is the pinnacle of pure mechanical engineering. The mechanic setting up the system must optimize the amount of fuel for a given throttle position, rpm and engine load. By using different pumps, jets, linkages and metering block settings, it is possible to deliver the correct amount of fuel in large
Induction Cleaning Service For Direct-Injection Vehicles
You may have seen it before: misfire codes, stumbling and suspicious fuel trim numbers. On a scan tool, the engine may show a loss in volumetric efficiency. The driver may complain about a loss of power, poor fuel economy, hard starts and a rough idle. But this is not a 12-year-old engine; it is only

7 Reasons Direct-Injection High-Pressure Fuel Pumps Fail
Don’t be scared by direct fuel injection diagnostics. In theory, these systems operate on the same principles as port fuel injection, but direct injection can inject more precise amounts of fuel into the combustion chamber so the engine can run leaner and more efficient. The key to direct injection is a high-pressure fuel pump. This
Bosch Introduces New OE Platform Fuel Pump Modules For The Aftermarket
Bosch is introducing new Bosch Original Equipment (BOE) platforms for its premium aftermarket turbine fuel pump modules. Covering select passenger car (BOE-C) and truck (BOE-T) applications, these fuel pumps bring the benefits of advanced Bosch turbine fuel pump technology to late-model vehicles and to many earlier applications with fuel pumps built on older technology. “The
