Where's the fuel filter for 2000 nissan frontier 3.3 ?

to check the feul pump. have some one in the back and turn the key to the start position and if you hear a buzzing noise the pump work. if you do not hear a buzzing from the gas tank. you need to chech relays

Clean injectors and check tps.

Maybe the spark plugs?

the fuel pump for most vehicles is in the fuel tank.

You don't hear it running when your turn the key on just before the crank position.

You have replaced the fuel filter and it was pretty much stopped up. (destroyed pump trying to pump through stopped up filter.)

Because it was going bad you couldn't drive fast because it wasn't pumping enough fuel.

Disconnect fuel line and see if fuel comes out when you turn the key on.

fuel preasure seems to be dropping off check fuel preasure regulator(gas) or leaks from fuel ilnes and loose fittings (diesel)

You have not run a engine control module fault code test, this is key to finding the possible causes. Borrow or buy a OBD2 code reader and check the codes
