Replace fuel pump om 1990 nissa 300zx

Sort of.
There should be a relay that provides power to the pump when you first turn the key on.
Then once the engine starts power is provided by way of the oil pressure switch. That way the pump won't run in an accident.
The oil pressure switch grounds the fuel pump relay on some models.

I have a 1991 niss 300zx non-turbo and it smells like gas when im driving

You may have either a gas leak or the evaporative canister on the emission control system is saturated. The canister cannot be dried out and must be replaced. This is part of the system to reduce toxic emissions and although may not be important, it is part of the road rules to maintain. You can purchase a replacement canister and fit it yourself. If this is a leak, then the only way to trace it is to run the car until hot with the bonnet up or clamp off the pressure regulator and run the fuel pump whilst examining the fuel lines for signs of wetness and gas smell.

How to fix an oil leak on a 93 tsi i cant tell if the turbo or somewhere else how do you cheack if the headgasket is bad because it smokes

there is only one way to track down an oil leak, you must pressure wash the engine top and bottom, then you drive it a day or so and look under the engine and on top for the source of the leak, common area's to leak are oil pressure sending units, valve covers, oil pans, rear main seal of crank shaft and front cover seal of engine.

300zx non-turbo smelling gas

Don't worry about the comment posted above. As long as you dont have a miss-fire or the car isnt running rough your injectors are most likely fine.

There are a ton of small and short fuel lines that run on these cars stock. Just check all the fuel lines under the hood and you should see or smell a small leak on the hose itself.

Timing on a 1991 nissan 300zx

There is no means of setting the timing if you are referring to a conventional timing light. The engine is designed with sensors that sense the angle of the camshafts in relationship to the crankshaft and whether it is on the intake or exhaust stroke on the #1 cylinder. This design is actually a little more complex than that because it has variable valve timing which means that the angle in which the camshafts open and close the valves, change with RPM's This give the engine the best of both worlds. It's like have an engine with cams designed for torque at low RPM and a set of cams designed for HP with a free breathing quick revving engine you would have on a race course. The ECM is constantly changing the timing and injector pulse width based on many sources of input, from, the O2 sensor, air flow, air temp, coolant temp, fuel pressure, RPM's and a host of other inputs.
SO>>>>>>>>>>>> in a manner of speaking, unless you are making reference to setting up the timing chain, everything else is under control by the ECM and related components.
