2002 Nissan Altima Questions & Answers
Why my 2002 Altima won't start?
There could be several reasons why your 2002 Altima won't start even though the engine is turning over. Here are some common causes to consider:
- Fuel system issues: If the fuel pump, fuel filter, or fuel injectors are not functioning properly, then the engine may not be getting enough fuel to start. You can check the fuel pressure and fuel pump relay to see if they are the issue.
- Ignition system problems: If the spark plugs, ignition coil, or ignition module are not working correctly, then the engine may not be getting the spark it needs to start. You can check the spark plugs and ignition coil to see if they need to be replaced.
- Battery issues: If the battery is dead or not providing enough power to start the engine, then the engine may not start. Check the battery voltage and connections to make sure they are in good condition.
- Starter problems: If the starter motor is not working correctly, then the engine may not start. You can check the starter relay and wiring to see if they are the problem.
- Mechanical issues: If there are any problems with the engine's timing, compression, or other mechanical issues, then the engine may not start. This would require a more in-depth diagnosis by a mechanic.
It's best to have a professional mechanic inspect your car to determine the root cause of the problem and make any necessary repairs.

I have a 2002 Altima 2.5 4 cyl I have replaced the 2 thermostats and still am getting no heat need help more ideas what to check .
You might want to try and reverse flush the heater matrix. This is the small radiator within the heater. To do this find the two hoses that lead away from the engine compartment to the bulkhead of the car. Undo them both from whatever joints you can find, you will get some coolant loss. Get a garden hose and turn on the water and allow the water to push through the matrix. Do this in both directions ie into both of the loose hoses then reconnect the original hoses top up the coolant, Don't forget to add antifreeze and hopefully a working heater.
Where can I locate the fuse on my 02 altima,my windshield wipers not working
There are atleast 2 fuse boxes in most vehicle's one in the cab typically under the dash somewhere and one in the engine compartment the exact layout of the fuses and relay's in this boxes depends on the make and model of the car but diagrams detailing the layouts can be found in the owners manual. Good luck
My 02 Nissan Altima started
VERY interesting ... Rodney2764,
I HAVE seen similar issues before...
Everything else seems to be good. I would be
thinking about having an
EXHAUST shop look
for a loose MUFFLER
baffle or
collapsing
CATALYTIC CONVERTER...
A rusted or loose part inside can COMPLETELY
block EXHAUST OUTFLOW...
It is not a COMMON trouble... but certainly worth
the look (while you are mobile (my opinion...
RATHER than WASTING time & money
buying A WHOLE lot of UNNECESSARY
oxygen
sensors ( get mistakenly replaced )...
(( from "
FREE" code readings )).
((( really difficult to resolve when you are immobile ))).
Hope this helps...

My 2002 Nissan Altima will
If you turn the key and the starter motor makes the engine revolve then it is cranking or turning over. If that is all that it does then it is not starting. They are two different situations. I hope that you did not replace the "crank" as you stated it was a sensor issue. The problem with a diagnostic code is there is a piece that activates that sensor and that piece can be the problem. The codes are the same whether it is the sensor or the tone ring. Also there is a gap specification between the sensor and the tone ring. If it is too far away, the sensor wont see the magnet.
Accelerator problem
the problem was not before but is after engine work
suggests harness connection , pinched wires to the inlet manifold
problem throttle control sensor or possible an ECM corruption
try using a scan tool to reset the ECm
