The car started spitting and sputtering then just quit. it would start then stop.i replaced the crank sensor,the ignition switch ,new spark plugs,oil and filter!v1a2n3d4

02 sensor is not you main problem.
Have you got good spark and fuel pressure when it acts up or quits?
Is it dead now or just acting up?

Pull the throtle body and replace the base gasket to start with.
Clear codes and see what comes back.

Check fuel pressure when it quits.
Post back fuel pressure readings.

Get some good repair info on the code for fuel pump relay and fuel pump and fuel pressure.
Let us know how it goes.

Crank position sensor?

check the wiring to the crank/cam position sensors or replace as required

If you have no power to the coil with key on, it might be the crank sensor. The spit and sputter ckould be a fuel problem, but if you have no spark now, check the crank sensor.

Sounds like something getting warm/hot as engine warms up. Could be the MAP sensor, Coil/Coil pack, Ignition Switch(not the key cylinder), or possibly the Oxygen Sensor.

Next time it does this, pull a plug wire out of the coil pack and hold it close to the tower, and have someone crank the engine to see if your still getting a spark.
Could also be a loose connector on the throttle body injection, or a broken wire.

is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.

I could be the CKP (crank sensor), but it could also be several other factors including the TPS. The correct way to start a diagnosis would be to see if any trouble codes are stored in memory. I'm assuming all basic ignition components are ok ; spark plugs, etc.

Check for fire to the coil pack. These have a tendency to go bad on these cars. Could be a cam or crank sensor, these also go bad. If you haven't changed the plugs in 30K, this is due also, wires every 60K. May need to actually get it hooked to a machine to find out for sure.

check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

Did your check the ignition coil? These tend to go quite suddenly.
