When was your last change oil sir? Spark plugs? Tune up? Check mo din fuel filter (every 20k ang palit).

Start first with the basics:
- Tune-up
- Clean the MAF (Mass Air Flow) sensor with electric contact cleaner (this should be done every 10,000kms with the QG engines on the Sentra which are sensitive to dirt).
- Clean the throttle body
- Clean the PCV (Positive Crankcase Vent)
- Check/replace fuel filter if this has not been done in the last 20,000kms.

yes sir, but the thing is pag tumirik na ang engine. ill just have to turn the ignition key off then after a few seconds (10-20 seconds) pagstart ko nagstart naman ng normal, meaning gumagana ang pump. thanks sir

you might be wrong sir. it could be shortage of fuel supply due to faulty fuel pump. gumagana ang pump kaso, kinakapos ang supply. kung may mahiraman kang electronic fuel pump sa suki mong shop, subukan mo muna trial and error. baka ito nga. it happen to me before, same scenario. hope this helps.

^another sign of a dying fuel pump is the pre-start (engine key "on") hissing sound common on some Nissans (not sure about the N16) is absent or faint before you start the engine.
