Nissan 300ZX Fuel problem

I'm having problems with my '86 Nissan 300ZX, when I start the car it will not keep fuel pressure, it just idles horribly and I can't even put it into gear without it dying. I'm not sure if it is the fuel pump because when I turn the key and listen for the hum of the fuel pump, it sometimes turns on and sometimes it doesn't. But one thing is for sure and that is that it will not stay on. So I'm wondering if it could be something that controls whether the fuel pump is on or off. Or maybe I just need to get a new fuel pump entirely? Could the fuel pump relays have anything to do with this? If so where are they located and how do I get them out. Thanks in advance. I have replaced the fuel pump,when you turn on the key the pump operates but does not purge.The on board computer gives a different trouble code every time you check it.This started when I replaced the battery and the clutch.It appears to be flooding the car.1984 300 zx non turbo

It sounds like the pump is going bad, check the voltage at the pump to make sure that it is good and constant, if it is, then change the pump. To find the pump, follow the fuel line from your gas tank.

Let me know if you are having any trouble or have any other questions and I would be glad to help, just ask

good luck

    The fuel pump is located in the gas tank. You can get to it by lifting
    up the carpet on the hump between your trunk and your seats.

If the car is a automatic then the connectors on the trans brain (located on the passenger side behind the spare tire) are getting wet. Try just wiggling them and see if it responds, if not unplug dry out and reassemble. Also fix where the water is coming in. I had this same prob and it drove me crazy.

My 86 300zx starts then shuts off

check the fuel rail for correct fuel pressure. If the Pressure regulator is faulty, the fuel pump will send fuel to the fuel rail, but it will be dumped back to the tank if the pressure regulator is bad, The fuel needs to be pressurised to go through the injectors and into the cylinders.

Good luck.

My 300zx idiling n starting problem

As a quick test,fill-up the tank and do not top off.

Monitor the starting problem.

If you're starting OK until BELOW 1/3 of the tank then it's a weak/failing fuel pump + filter filter.

A fuel pump will perform poorly when it's low on fuel.

An old fuel filter will reduce the fuel pressure and cause the fuel pump to work harder.

Also check the gas cap for deteriorating plastic seal.

I need to find the ecu relay for an 86 Nissan 300zx.

The ecu is probably under the passenger seat. The battery also has a fusible link which may be blown. Also follow the battery wiring to the regulator box. This may also be faulty

Nissan 300ZX Fuel problem

I had an 82 280zx and now a 90 300zx, in both cars the fuel pump relays were located in the engine compartment, in the fuse boxes, as long as you can read the covers over the fuses, they are clearly marked.
2nd no fuel at filter would either be faulty pump or relay. All that the regulator does is regulate the pressure to the injectors and keep them consistant.
