I am not sure where in a Sentra, but in a Quest 1993-02, it is in the distributor (integral). Common problem with Quest is that brown dust covers optical sensor under slotted wheel under rotor. If dust, the bearing is failing and you need new distributor. Clean optical sensor and see if it starts and runs. Get dist. on ebay.

report back on progress.

    to clean temporarily, remove distributor cap, remove rotr (1 screw), remove slotted wheel. clean optical sensor. If it starts now, it will be temporary.

My 2000 Nissan sentra stops after driving over 30 minutes.


Does it start back up? If so do this, buy a can of engine throttle body cleaner (made by CRC products) and clean the throttle bore and blade, also clean the idle speed control air bypass valve mounted to the throttle body.

Hi can any1 help me with my nissan sentra problem?my car just shut off while driving and lost power be for it shut completely off tried to crank it back up but it didn't start sprayed some starter


Crank shaft sensors often fail without triggering a code. But in its early stages, a check engine light may be on. Symtoms of a bad crank sensor are: poor acceleration ( lack of power ) rough idle, ETC. sometimes you may be able to start it normally, and other times it takes 3 or more times. If the check engine light is on take it to a auto parts store and thy can read the code for free. To tell if that's the problem. God-Bless!

My 1993 nissan sentra 1.6 wont run and check engine light wont turn on,bulb is ok


Could be any of several things. If the crank sensor is marginal and not sending pulses, the fuel pump is shut off. This is for safety. The pump is energized for a few seconds as key is turned in preparation for starting then engine must rotate normally to keep the pump on. If it stops, in a few seconds the fuel is cut off.

I have Nissan Exalta2000, it would power off all of a sudden while driving, the 4 icons on the dashborad lit up and if I stop tha car wont start. it happens 3 times and if I get a mechanic they cannot...


hello there, had to do some looking up as to what NISSAN EXALTA 2000 actualy is. i reside in USA and we do not have exalta on our streets. here, its a powertrain aka engine and transmission in a NISSAN SENTRA so it should be very similar to our sentra as far as setups except for different body. I think that you have an issue with the CRANK ANGLE SENSOR. i would start with replacing the sensor. is the SERVICE ENGINE SOON light on??? if so, that could be for many reasons and one of them would be crank angle sensor issue. nissan had problem with those sensors. they would cause the car to die. nissan had campaign / free replacement program in those model years of nissan sentra 2000 year model. have the crank sensor replaced. start there. like i said very common problem.

Car wont start


A few things might cause that, ECU, Fuel Pump/ Crank/Cam Sensors. You may want a nissan dealer to take a look at it.

Nissan sentra keeps shutting off while driving


~lopez:
I had similar problems after getting my ECU replaced.
later i got a letter from nissan saying it was the wrong program they flashed on the ECU (think it was a maxima ECU they flashed into my sentra)
it only seemed to do it right after my car warmed up while i was slowing down (for a stop) but never cut out when i was at a complete stop.

you can call nissan to see if there are any recalls or updates for your ECU program (they should be free if there is)

if that does not work, or it cuts off while accelerating, try checking your fuel/air ratio, spark plugs, air filter, and fuel injectors. (a fuel filter can even cause cut-outs as well if it's seriously clogged, but it's usually hard to start as well)


~guest:
kinda sounds like heat problems, check to make sure your temp gauge is working and see if this helps...
- when it cuts out on you, turn key all the way off, then turn it back to full on (but don't crank) this should let you rad. fan run without cranking your car. if this causes the wait time to be shorter before you can crank it again (less than an hour) then it's most likely a temp gauge, water pump, hose or even a belt.
