SOURCE: 1990 nissan 300zx nonturbo - change alternator belt how?

If you look at the front of the alternator, behind the belt, you'll see a curving grooved metal track - that's the adjuster track for the alternator. There's a bolt going through the groove into the alternator, which holds the alternator in place. You need to loosen that. I believe it's a 14mm bolt. You may also need to loosen a couple of the 12mm bolts that mount either the bracket or the alternator, to allow it to move. You'll probably find that it's easier to cut the old belt off (so it's out of the way) and then do the bolt work with a little more room to spare. Belt changes are always a pain on these cars - stick with it even if it takes awhile. If that doesn't get the alternator loose, loosen or remove other bolts on the alternator mount or on the track mount, and it will move eventually - not much, but it'll move. You may find that you can partially seat the belt on the alternator pulley, but can't get the belt fully onto the pulley. If that's the case, get it as far on as you can, and then put a 27mm socket on a long breaker bar, put the socket on the crank pulley bolt, and with the car in neutral, rotate the crank pulley by hand. This will pull the belt onto the alternator pulley.

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.

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.

No, that is not true, you can only use one from another 300ZX, 1990-91 for a manual transmission, 1990-93 for an automatic. Also you have to get the one for if you have twin turbo, or one if you don't.

That means the transmission is going into Limp mode - something's wrong that is making the car believe it can be damaged by the speeds the upper gears will allow you to reach. For starters, check the fluid level (or just change it - it's not a bad idea), and disconnect the battery for an hour or so to put the ECU into relearn mode - this will clear current fault codes and allow you a fresh start to see if the condition reappears, or if it was a fluke failure of some part that caused the car to repeatedly go into limp mode.

Loss of power at 2400 rpm's


Check your mass airflow meter. If it's bad, at least on my 1990 300ZX, the car won't rev over 2400RPM (it's a safeguard built into the ECU of the car). Grab one from a scrapyard and swap it in and see if that fixes the issue.
