Sediment, rust and debris from the pump can get into the tank and kill the fuel pump. This video is sponsored by Carter.
Thumping Noise At Cold Start On Honda Accord
Honda Accord owners may report a thump as the ignition switch is released from the start position or as the engine starts. This noise sounds similar to a rubber mallet striking the frame and occurs only on a cold start (the vehicle has been sitting for some time, usually overnight).
Toyota Tech Tip: Rough Idle, Surging Between 500 To 800 RPM
The owner of 2005 Toyota Avalon complains check engine light is on, rough idle and engine idle surging between 500 and 800 rpm. The technician retrieved Diagnostic Trouble Code (DTC) P0171 and P0174 (System too lean banks 1 and 2). The technician replaced the air fuel sensors on both banks and cleared DTCs. After driving vehicle for approximately one mile, all symptoms returned.
When Should Hoses Be Replaced?
Before they fail is the short answer. The long answer is it depends on the type of hose, the age of the vehicle and the application. Today’s cooling hoses, fuel line hoses, vacuum and emissions hoses, PS hoses, A/C hoses and brake hoses are all very durable and long-lived, but they don’t last forever. There are no factory recommended service intervals for any type of hose, but all automakers do recommend inspecting hoses when normal maintenance or repairs are performed.
Tech Tip: Fuel Filler Necks And Related Check Engine Light Conditions
Since the introduction of the OBD II system, manufacturers have continued to improve on the monitoring of evaporative emissions, with the complete evaporative system being under a scrutinized surveillance. Codes like P0440 to P0456 are all related to the fuel vapor control, including leaks.
Veyance Technologies Expands Coverage with 104 New Part Numbers in Automotive Aftermarket and Heavy-Duty Lines
Veyance Technologies, manufacturer of Goodyear Engineered Products, has announced the release of 104 new part numbers to its automotive aftermarket and heavy-duty product lines for the second quarter of 2012.
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.
Tech Tip: DeLorean Fuel Pump Replacement
DeLorean owners and enthusiasts know to be wary, a car left sitting that long and havoc ensues with the sensitive fuel system of a 25-year-old DeLorean. In fact, any car, left sitting for a lengthy period of time will eventually encounter fuel problems. One specific problem to note would be the need for a new fuel pump. Cars left sitting, and even daily drivers, can fall victim to fuel pump failure. Over time, debris and contaminants build up in the fuel tank.
Diagnostic Solutions: Solving Insufficient Fuel Problems
Solving cranking, no-fuel or insufficient-fuel driveability problems on late-model imports can be challenging, especially if a technician doesn’t take into account the way that modern fuel systems operate. Some vehicles, for example, limit vehicle speed by deactivating fuel injectors. In some rare cases, a miscalculation in vehicle speed can cause an insufficient fuel condition.
Independent Research Shows E15 Poses Minimal Risk to Older Vehicles
The conclusion of the Ricardo study is that the adoption of E15 as the blend limit for standard US pump grades of gasoline should not adversely affect vehicles manufactured between 1994 and 2000.
Groups Form To Delay E15 Fuel
The groups contend that E15 could harm many types of vehicle engines, fuel systems and components, as well as the environment.
