Please help, I have tried just about everything and still need help!!!
I have a 97 hardbody, 2.4L, manual tranny, 4x4 and I have replaced fuel filter, plugs,wires,rotorcap and rotor button, air temp sensor(which was shwing a code for when the engine lite came on, which came back on after about 24hrs) and I also replaced a bad vacuum line that went into the throttle body but I still have a miss from 2000 rpm and up and it's not all of the time but most of the time. I am just about ready to take it to the Nissan dealer but really would rather save the money and do it myself. Could someone please help me out? I would greatly appreciate it.

If you engine is a 2.4 liter it's on the passenger side center of the engine compartment, the hoses from the fuel filter conncts to the throttle assembly . You may have to remove the air filter housing to see it. It is a round canister hoses held on with fuel line clamps. hope this helps
Sounds like pump drawing too much current , and by putting in a heavier fuse like that your just asking for a fire. Have a fuel pressure test done, that should confirm if pump shot. My guess is that it is. You have tried new fuel filter to see if that helps at all didn't you? When/if you pull the pump out, have a look for excessive dirt, which is always a consideration. Any blockage will make pump work harder, thus cause a higher amperage situation also.
With a vehicle that old I think you should retrofit any pump that matches within reason the original specs as with throttle body injection fuel pressure is critical. If it is the same as South Africa the agent will sell you any **** to get rid of you. Try fitting a Bosch pump with a pressure regulator (set it to spec ). Please change the filter.
