What does it mean when a fuel system fails?
The fuel system operation is issued a pass. • A HEGO sensor indicating lean at the end of a test is trying to correct for a perceived over-rich condition. • The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
What does the diagnostic code for fuel system mean?
The descriptors for these codes indicate that there is a lack of switching from the upstream oxygen sensors as indicated by the processor. We begin our analysis by checking to see if the fuel system is working as designed.
What are the symptoms of a bad fuel filter?
As is the case with most automotive filters, over time the fuel filter can become excessively dirty — to the point where it can no longer filter out particles efficiently, or even restrict flow. Usually, a faulty fuel filter will produce any of the following 4 symptoms that can alert the driver of an issue with the vehicle.
What is the current rate of fuel failure?
Fuel failure rates are now at a low level (<10-5 or <10 ppm) and continue to be reduced. However, fuel failure has remained a very important issue for NPP operation and economics.

How can you tell if your fuel pump is failing?
If you ignore all of the other warning signs of a failing fuel pump, it will eventually fail completely. Once your fuel pump has finally given up the ghost, no fuel will reach your engine. You may hear your spark plugs firing when you try to start your car, but without fuel, the engine won’t be able to turn over.
What is the probability of an engine failure?
A power failure in either phase of flight is likely to be equally fatal; 30 percent end in fatalities. The fatal probability is lower for approach-phase engine failures and we have a theory on that, too.
