EVAP code,where is fuel pump located on 2003 Oldsmobile Alero?


If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

Diagnostics is a term for what must be done to track down the causes of any problem in either system, the fuel pump or the evaporative (fuel vapors) emission control system.
The fuel pump relay is PART of the fuel pump control circuit, there are other parts like the computer control and the ignition switch
The electric vane rotary fuel pump is well a fuel pump, the control circuit (fuel pump relay, wiring and PCM) is what powers the pump on and off, like the switch that turns on a lamp, part of the same system but two different things. The fuel pump itself is located inside the fuel tank, the electrical control circuits are in various places like the fuse box and the wiring runs all over and then back to the fuel pump eventually. Evap code are generated in most cases by a fuel vapor leak, this is snesed by the computer via a small pressure sensor.

This details will help.
Thanks.
