    The sensor by the filter is the sending unit, there are only two wires, which means its a sending only unit. I need the oil pressure sensor, also called the switch

1985 Nissan 300ZX I want to disable the fuel pump to relieve the pressure before replacing the fuel filter. Is it a relay or a fuse?

No need to remove any relay. Proceed as follows:
- Park the car in shaded and well ventilated area.
- Remove the negative battery terminal.
- Loosen the fuel cap, fuel filter banjo bolt, push on or pipe clip.
- Wrap a piece of cloth around the connecting end of the pipe and remove the pipe.
Let the engine cool down about half an hour before you proceed.
Keep your eyes away from the gasoline splash.
Keep any flame away.
Dry up the area immediately.
It is always better to get the job done by a qualified personnel.

I have a 87 nissan 300 zx and the alarm is keeping the car from starting what should I do

Locate the alarm power wire and trace it from the alarm to the power source it is connected to and remove the fuse from the line or cut the line. If that resolves the problem the alarm is at fault. If it doesn't locate the kill switch and replace it.

Digital meters/inst.on dash dont work/come on

Check the digital dash power supply. You can find rebuilt, new or places that will let you send in your power supply and they will repair it for you. The cost ranges from about $50 to $150 US depending on wether you do the entire dash and power supply or just the power supply. The unit is fairly simple to access and replace just a couple screws and two pluges to take out. The power supply is a silver box about 3.5 inches x 3.5 inches x 2. inches thick and has two tabs extending from two oposite sides with a hole in each for the screws. The unit is located under the dash on the driver side just behind the botom plate under the steering column as best I recall going off memory.
