ok new problems it has been a week since i drive the car, being off work i really have no where to go i never did listen and change my Crank Sensor, but today it did it again and i noticed that some of you said that it happened to you but when it tried dying and you gave it gas it would keep going, well i tried that today and it surely just died i am not saying the the sensor that you guys recommended to me is out of the question but is there anyway that this could be fuel related ? i have already !.changed plugs and 2. changed the fuel filter, and ever since this problem my gas mileage is sucking could there be a bad injector, or maybe water in the fuel tank ? fuel pump maybe ? i am trying to elimate things one by one but i have a feeling that it all could come back to be the same thing from the beginning
 


Well certainly anything is possible. One way to partially eliminate fuel would be to have a fuel pressure gauge on the schrader valve when it dies, but thats not likely to happen or all that easy to do. You could get a fuel pressure gauge and after it dies, hook it up to the schrader valve and see what the pressure is. If its within a few psi of where it should be I would think you would be good. Its not the ideal way to test that, but I would think that if fuel was the problem, particularly a pump issue then pressure would be way low at the time it dies.

However, keep this in mind. The CPS controls spark. If it goes, then you have no spark and you can dump all the fuel you want but no spark, no boom, no go.
 
well it cranks with ease it it just weird that whenever it does do it and i try to give it a gas to keep running it does nothing for it
 
"Giving it Gas" is realy only opening the throttle plate, if the CPS is bad this would happen, the engine can have all the air and fuel, but without spark it is not gonna keep running, sorry but if you want a quick test, while the car is doing this no start thing remove both spark plug wire from one coil, \(the spark will jump the gap) if you are by your self you will hear it if you listen, if there is no spark while cranking Replace CPS and test again
