1996 Nissan 300ZX Questions & Answers
I start my 300zx it
if the pressure at the fuel rail is within specs, I believe your injectors may be clogging. This is all I can offer with the information you have given... reply and elaborate if this doesn't help you...MK
HI HAVE A NISSAN 300ZX 1991 MOD MANUAL THAT HAS 2 PROBLEMS [1] IT SOMETIMES IDLES TOO HIGH AND THEN JUST CUTS BACK TO NORMAL[2] IT IS VERY HARD TO START WHEN HOT .COULD THIS HAVE ANYTHING TO DO WITH T
The chokes now operate with temperature sensors. The sensor sets the "cold start" cycle which will rev the engine by advancing the spark and the fuel richness. It is only suppose to last less than 2 or 3 minutes.The O2 sensors are suppose to warm up to signal the computer that it can go into normal mode. Some O2 sensors have a built in heater to help shut down the "cold engine" cycle sooner. If your O2 sensors are not heaing up with this feature burned out, then the engine will stay revved up longer.This can also affect a later startup as the engine is not resetting for a warm engine. So you have 2 possible things wrong. A defective engine temperature sensor and bad O2 sensors with burnedout heaters in them.Some O2 sensors can be tested by a mechanic going under the car and unplugging the wires on the O2. The temperature sensor may be one of 2 in your car. 1 sensor runs the dash gauge and the other works the engine management system.
Where is the stoplight switch
Hi,
It is under the steering column tube bracket, when your under the steering and dashboard, push the brake pedal and you could see a small rod w/ 2 wires connected to it.
Hope that helps you out.
Where is the transmission dipstick located on a
A manual transmission does not have a dipstick. You check the gear oil in it by finding the upper plug in the gearbox, removing it and placing your pinky in there to feel the oil level. Optimumly, a small amount should drain out when you remove it, indicating it is full. If not, use a funnel and usually 80/90 weight synthetic gear oil to fill until it runs out of hole. Replace plug using thread tape on plug threads and tighten firmly. This is done from underneath vehicle preferrably not raised unevenly on a level surface, or on a full car lifting rack. If the transmission is not level as if in your garage on all 4 wheels, you will not get a correct indication as to the amount of gear oil in the gear case.
Please rate this answer! Thanks, Mike
My coolant tank keeps breaking
If your coolant tank is pressurized past what the tank is rated for, the cap is supposed to vent the excess pressure over it's rating. You might need to replace the cap, but there is the issue of why your pressure is too high in the tank in the first place-usually that is caused by a combustion leak in the cooling system . like a blown head gasket (or worse).
Replacing fluids 0n 1996 300zx
radiator antifreeze: open drain **** on radiator and drain refill with water re plug and leave radiator cap off. start vehicle. watch when coolant drops or rises drastically as that is the thermostat opening. at that time re open drain **** and fill radiator with hose water at the same time. when water coming out is completely clear again turn vehicle off and drain radiator again. fill with antifreeze and water mix. 50/50
oil: jack up car, find oil plug, directly behind steering rack on oil pan. undo plug and drain oil into container. while oil is draining remove oil filter. wait for oil to drain completely then re-install drain plug and new oil filter(filled with oil) undo oil cap and pour in oil 4.5 quarts on n/a and 5 for turbo. tighten cap and your done.
brake system: dont attempt, use an experienced mechanic as the lines need to be bled in numerous places including inside the car from the abs module mounted behind the passenger seat.
easy brake system: individually bleed brakes while adding fluid until clear fluid comes out. (not efficient)
a/c: do not attempt unless you have an evac pump for ac systems.
clutch: same as easy brake except using the bleed valves at the slave cylinder and on passenger side fender well.
washer fluid: add fluid and squirt a little to make sure there is no air in the line
96 300zx. What would cause a steering dead zone?
Could be the steering rack is worn out. But there is some adjustment I believe.
But before you try to adjust the rack, make sure the tierod ends are not loose, there is no play in and out on the steering shaft, and there is plenty of power steering fluid.

Text from Nissan service manual troubleshooting section:
Step 1: Check to insure battery is 100% check voltage output. Should be up there at least 10 volts.
Step 2: Check starter
The guide continues, but one of these is your problem if your engine and system run fine after engine start.
Will not shift into park
its a vacuum leak to the left side fuel pressure regulator. find the hose that goes to the balance tube and follow it all the way back to where it connects to the manifold pressure. if you find any cracked or bad hoses i would suggest replacing them. if not the fpr could have gone out.
as far as park is concerned it sounds like the park saftey switch by the brake pedal. there is another sensor on the transmission but its very unlikely to go out.
WHAT ALL DO YOU HAVE TO TAKE OFF WHEN REPLACING
in order, clutch fan and pully(4nuts), radiator(optional for ease) rubber water pipes, hard water pipes on engine, timing covers (optional for ease) then unbolt the six(?) bolts holding the pump on and pull off. make sure to remove all old gasket residue before replacing with new pump and gasket
Oils seals on a 1996 Nissan 300ZX
If he is talking about the rear and front main seals, they can be pretty pricey considering you have to drop the oil pan which might or might not have enough clearance without either jacking the engine up or dropping part of the drivetrain. I would take it somewhere and get some estimates.
