Possible crank position sensor

Check for fuel and if getting fuel check for spark as it is a problem that you will have to run down disconnect your fuel supply from engine and crank if fuel pumps out then its most likely spark then you must track it down are you getting spark at plugs if not then check your cap and rotor if so check your wires it is in there somewhere I cannot give you direct answer without looking at the car.

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!

----------This will help.Thanks.

Since you've handled the usual suspects, I'd suspect the coil and/or power transistor in the distributor.

good day. try to check the spark plugs,air filter, ignition coil and the wires i hope this will help you.

CHECK FOR SPARK AT SPARK PLUGS, CHECK CRANKSHAFT SENSOR, CHECK FUEL PERSURE, ALSO CHECK FOR INJECTOR PLUSATION.

Try replacing the Fuel filter, if still no luck check the pressure of the fuel at the fuel rail under the hood of the car.

Its possible, that you crank angle sensor is failing. Also, that vehicle had a issue with the ECM/computer. Nissan put a set of foams inside of the ECM box to prevent the ECM from movement, however the glue that they used to attach the foams was causing the ECM to fail. The vapors from the glue would eat up vital circuits inside the computer causing failuer. I would go to your local dealer and provide them with your VIN nujber. With the VIN number, thay can check to ysee if the foam campaign has been doen and also the crank and cam angle sensor camaign. Nissan volunteraly replaced cam and crank angle sensors if the VIN number matches the campaign. Your ECM/computer is covered for 8years or 80000 miles. We are also starting to see timing chains getting stretched causing running issues, but you will have a "check engine light on" for cam angle sensor circuit. Anyhow, go to your local friendly NIssan dealer and have them run your VIN number to see if you have any open campaigns (crank and cam sensors, ECM foam etc.) Good luck and let me know what you find.
