My 2003 Nissan Sentra died while I was driving on the freeway. I was able to start it but it died again the following day and it will start anymore. I was reading the forum and suggest that it's the fuel pump. Are there any other fix aside from the fuel pump? Fuel pump cost around $800. I want to make sure before I spend $800.

For which component or system?

There is an internal problem in the transmission. That why it's default to neutral. You to replace the transmission or get rebuilt.

Sounds like the fuel pump is bad.... I would have the codes read and start there... but my imediate suspicions are the fuel pump.

i have the same problem and my mechanic told me that it was the camshaft position sensor wire plug and sensor but its still the same, let me know if you find out what it is

good day, try to check the coils spark plugs air filter i hope this tips will help you.

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

window regulator is bad.

Check your fuel pump pressure and filter.

try replacing the crankshaft and camshaft sensers, my 2004 sentra spec v had the same problem.It cost me $122 for both the sensers and can be done in 20mins

sounds like fuel starvation...check the fuel filters and the fuel pump
