Question about 1986 Nissan 300ZX

4 Answers

My daughter's '86 Nissan 300zx non-turbo is able to start and idle but engine dies after about 30 seconds as if fuel is cut off. Engine dies immediately if you try to rev the rpms above idle. This problem began immediately after someone tried to jump start her battery but reversed the battery cables +/-.

Could it be immobilized? Check keyless remote if have one. Cars start and die if immobilized by the security system.

SOURCE: How do you change the fog light bulb on 1993 zx?

Take out the small screws that hold your turn signal/marker lights on. This will allow you to reach in and undo the three (if I remember right) 10mm nuts on the back of the fog housings that hold them in the bumper. Once they're removed, press on the back of the fog housing and the foglight assembly will pop out of the bumper. Then you can replace the bulbs.

What I did on my Z is something you might consider - while I had them out, I took them apart (just a couple screws and bolts, very easy). Open it up so that you have access to the glare guard - the cup that sits in front of the bulb. This blocks forward projection of the light, and instead bounces it onto the reflector to be spread very wide (but not far forward) in a fog beam pattern. I used pliers to physically break the guard off the housing, so that instead of a wide, shallow fog pattern, I had a forward-projecting driving beam. I also swapped the 35w OEM bulbs for 55w higher-output superwhite bulbs (this increase in power consumption is not enough to cause any risk to the wiring or fusing, by the way - it worked for years for me). Then put them back together and reinstall them - you'll find a drastically improved light pattern for night driving, and they're still low enough to the road to cut under most fog. Especially since I always felt that the Z headlights were pretty pathetic for output (at least until I installed HID lighting), this was a great mod to make to the car.

SOURCE: 1990 300zx non-turbo coupe 5 speed

Old post but I would like to state that white smoke and white vapor are two different thing and blue smoke is sometimes so ligh it looks white but does act like heavy smoke. Evanescence of water vapor looks a lot like smoke but dissipates a lot quicker but in mass quantities can look like smoke (yes..I been dying to use that word ever since I heard of the band Evanescence lol). Transmission fluid can be sucked into the engine via a bad shift modulator both that has no bearing here (just FYI). In either case you would be fouling out spark plugs due to oil or water saturation and causing unburned fuel to be expelled.

SOURCE: 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.

SOURCE: Engine either dies or revs high at stops-86 nissan pulsar

Its vacuum hose related. Mine does the same thing. Am looking for a vacuum hose diagram so I can take off the carb..... Check your vacuum hoses for leaks by spraying something like WD-40 on them and look for bubbles.

SOURCE: 86 300zx turbo cuts out at 2300 rpm

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.

It sounds like the number 2 injector is hung open.

It will dump fuel and cause all sorts off issues with the ECU.

You should ohm that injector and compare it with the others to see if it is wildly different. If so, change it out and retest.

It could be a couple of things. I first guess is to check the fuel filter. If it has not been changed out within 15-25,000 miles deposits that within the gas tank has restricted the flow and will cause a hesitation or very rough idle. Now the desposit could have surface close to the injectors restricting the flow. Second, tune-up ( distributor cap and button, spark plugs, wires, etc). Third, check all you fuel hoses leading (especially leading from the fuel filter) to and from the engine.If they have never been changed, I would do so. Hope this a start of resolving your problem.
