car has 300,000 miles on it... I was driving @ h/way speed & the engine died as if the switch had been turned off. Will turn over but will not fire. no funny sounds when turning over. All dash lights working. fuel pump & filters replaced last year. Distributor & timing chain replaced 5 years ago. Average 20,000 miles per year. I've never had a problem with this car & it has been maintained.

Listen to John Paul above --- he knows his stuff!
If it's not dist seal....Sounds like 1) a fuel pump, 2) oil pump (which shuts off the fuel to save an engine with no pressure, or 3) the timing chain broke.
At that age it's probably a fuel pump. Check the fuse and breakers on the pump first. Even if it's blown, you need to know why. Then find a good Nissan mechanic who can test fuel pressure before you just slap one on it. If fuel pump is good, then I'll bet it's oil pump broke and the system worked well by cutting the fuel before the engine starved.
Since the KA25 engine has a chain, it doesn't usually go. If you have a socket large enough to get it around the crankshaft pulley ( I believe its behind your right front wheel and is 27mm or so and a 2' breaker bar -- disconnect negative on battery, put in neutral and turn engine by hand. You should feel normal compression and release variations, but no stopping or metal noises. If the chain broke your valves are smash and the engine is hard to turn.
PS: To Raymond K - who says "buy American" LOL -- how many American cars has he bought as cheap as an Altima that have given him 300K? ZERO! He's lucky if he can get 200K out of a very select few.
Good luck to ya. Those old Altimas give a lot of miles for the buck!

I am having a couple of 'dying' problems with my 93 Altima - though only twice at stop lights - possibly when it was not warmed up properly. After a while it DID restart. (Answers?)
But the problem which sounds most like yours - and happened on the highway; ( where the revs also went down to nothing) WAS the distributor, which was coated with oil, maybe from rustproofing.) Since I replaced that a year ago, the car has worked fine, except for the stop light problem. Good luck! That does sound like rather a lot of mileage, though it is a great car. Mine has 170, 000.

Much as I hate to admit it, John has a good point there.
However, so does Pealius.
I wouldn't discount either of those problems.
Just before you clean it all up check the coil for white marks on the rubbery plastic, that would be a sign you need to replace the coil itself.
I also found these Technical service bulletins for your car.
If it is difficult to start the engine (the starter operates, but the engine does not start) in a 1993-1995 Altima, the cause may be low base idle speed adjustment or an over-rich air/fuel mixture during cranking.
If Idle speed adjustment doesn't do the trick, check the ECT.
1993-1994 Model Year
A countermeasure engine coolant temperature sensor, which provides a leaner air/fuel mixture ratio during engine start-up has been developed for this incident.
connect a tachometer (digital readout if possible).
2. Start the engine (the accelerator may have to be opened and/or the fuel pump fuse removed during cranking to get the engine to start), and warm it to operating temperature.
clean and dry the spark plugs, and attempt to start the engine again.
3. Run the engine at 2000 rpm (no load) for two minutes. Then shut the engine off.
4. Check the oil level and correct if necessary (between the "L" and "H" marks on the dipstick). If the oil level is overfull and has a gasoline odor, change the oil and filter before performing this procedure. If the crankcase is overfull with oil, idle speed adjustment may be affected.
5. Disconnect the throttle position sensor (TPS) connector. Now re-start the engine.
Note :
When the engine is in this condition (TPS disconnected), the IACV-AAC valve and the ignition timing are held in a "fixed" position, and the idle speed is called "base idle." If the engine stalls with the TPS disconnected, the base idle speed is adjusted too low. Temporarily increase the base idle speed by turning the adjusting screw on the IACV-AAC valve until the engine will idle.
Note :
On 1989-1994 Maxima's (J30) with VG30E engine the IACV-AAC valve is a "stepper motor" type valve. To set base idle on these vehicles, set the ECCS ECM mode screw fully "clockwise". This will close the IACV-AAC valve completely to allow base idle speed adjustment. Return the ECCS ECM mode screw fully counter-clockwise after setting the base idle (see step 9).
6. Rev the engine 2-3 times to 2000-3000 rpm, then allow it to idle (all accessories "off").
7. Check the ignition timing with a timing light and adjust it to specification (if necessary).
monitor the idle speed using the tachometer connected in step 1.
Check the idle rpm and adjust to specification (if necessary) using the screw on the IACV-AAC valve.

94 Altima

Sounds like the answer oil inside of the distributor. Many high mile Altman have blow by pressure escaping the piston rings. This pressure tends to blow oil past the distributor shaft seal. Remove the distributor cap unbolt the rotor remove the black plastic cover under the rotor #2 Philips bolts and wash out the oil with electric motor cleaner or Auto Supply brake parts cleaner. If you have compressed air to blow dry or even a blow drier. Now dry reassemble black cover, Notice the distributor rubber seal is now oil soaked and has swelled cut a small segment out of the seal along the bottom this will allow future oil a way out. Or just go buy a new distributor only $450.00 or $125.00 for a rebuild aftermarket Auto Supply. Good Luck

Crankshaft position sensor failure can cause this problem. Usually the car will start back once it cools down but not always. Have seen this exact problem with mercedes benz. Check for spark at plugs to rule out ignition coil failure, not sure if that car has one or several.

It could have been flooded , it is very common in fuel injected cars , let it sit for a while don't rey to start it while its sitting , change the spark plugs and try it , or it could be a clog in your fuel injector or the gas lines , it could be anything the best thing woud be to take it to a shop

sound to me like the timingbelt snapped if it did you may have bent some valves unless it is a free wheeling engine
