Top 20 2002 Nissan Altima Questions & Answers

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.

Use Nissan Altima Automatic Transmission Fluid and it should hold about 10 quarts total. I would fill with 9 quarts and start the engine and circulate the fluid. Check the fluid level and add what you need.

You have to check battery terminal for looseness, also you have to clean them carefully to remove any dust of carbon buildup

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.

I know of no reason why you shouldn't do that and I have seen cars with a loose ribbon cable in the boot...

no. typically the whole engine is lowered out with the trans attached then separated.

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

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... Carnac the Magnificent

you should be careful who you buy a 16 year old car from. likely it isn't worth fixing.

Yes, there is a way to reprogram your car to lock the doors when the gear selector is put into Drive. Follow this site for a complete step by step re-program of the door locks: http://www.nialtima.com/automatic_door_locks-113.html

Heater core may be clogged. Try flushing it to see if water flows through freely. Also check the heater water control valve for restrictions.

Blinking means that the problem is so bad that it can damage the engine if you drive it. You need to get a code reader from an autoparts store and read the codes to see what the issue is.

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.

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
