Disconnect both battery cables and touch them together for about 5 mins. That will completely drain the capacitors in the ECM and clear all the codes.

SOURCE: where is my fuel filter 2001 nissan altima

Most of the time there is an inlet screen/filter in fuel tank attached to fuel pump. But there should be another filter between tank and fuel rail. it should be located on the firewall, so if you work backward from an injector toward the gas tank you will bump right in to the filter along the way.

Nothing counts until you fix the issue causing the light to illuminate. After that the scan tool can reset the light, or you can disconnect the battery and it will reset.

I have a 2001 nissan altima and i really need to no where is the fuel reset button please help

Doesn't have one . Do you know how to test automotive electrical circuit's ? Viewing wiring diagrams to see what all is involved in the fuel pump electrical circuit ,then using a DVOM - digital volt ohmmeter to test the circuit. Fuel pump has a relay that is energized by the ECM - engine computer , the ECM will only energize the relay if it see's a signal input from the crankshaft position sensor an if no problems with the anti-theft system . Finding out where the relay is located on the vehicle an pulling it out an test Battery power an control for the relay is how to find the problem .https://www.youtube.com/watch?v=Gg20X-FwGzg&t=36s
