2001 Nissan SENTRA GXE with 1.8L. PROBLEM: CAR died 2 times on the highway, after the second I could not get it started again and had it towed home. Battery is strong, engine cranks good but does not fire. Plenty of gas. I replaced the Crank Position Sensor, but still wont start. I charged the battery and tried to start while changing. It just CRANKs over smooth and won't start!

SERVICE IT .....OIL PLUGS, AIR ,FUEL AND OIL FILTERS GET TROTTLE SENCOR AND THE MASS AIR FLOW SENCOR CHECKED
SOURCE: I need to know where the crank position sensor is
it is wher the engine meets the transmission..on the flywheel...and the oxygen sensors bank 1 is the one before the catalyst....and bank 2 is the one after the catalyst....
Testimonial: "Well my 01 sentra 1.8L GXE has 2 banks, 4 oxygen sensors, it has the 2 catalitic converters on the exhaust manifold"

Hello, Thanks for looking me up. It is story time. From my 25 years plus experience, even if alternator test fine, or battery test fine it does not mean it is fine. Here is the deal, a lot of times, a battery will test OK, but to have it test right it needs to be put under a load. There are meters to do this, and same with alternator. First thing I would do and have done, Is if you car started, get it to a battery exchange place. I am sure in your area, you have these places all over. There little battery shops that only service or sell batteries and alternators,
Advantage to that is, they can put your car under a load, and test your out put of the battery, and alternator, to make sure they are producing the amps it needs to charge. Now, this is after you take some time and check your alternator belt, to make sure it is tight and not slipping, and follow the wires from there down to the battery. Make sure all your connection are good and clean and tight. Sometimes the positive lead going to the battery from alternator, might have a inline fuse in it, and check it, and replace if needed, Check to make sure the ground wire from your battery is clean and the part that is bolted on the frame of the negative from battery is clean service and tight. One thing I am going to ad here, that i did not see mentioned, is sometimes the connection lead to the starter, cause a draw or back ark of amps via the battery, which also will cause battery to drain. Kind of like playing tug a war.Meaning if the leads going to the starter are bad connection could also cause a draw via the 12 volt system. Utilize places, like fire stone, sears, or even those little battery/alternator quick shops I was telling you about, as they have all that fancy testing equipment to pin point it. AND another fact I will let you know, did you know alternators if getting worn will fluctuate , meaning will work and then not work and work and not work. So, sometimes a guy will check the alternator and test good at the time, but then sometimes it doesn't. I hope this helps Mike

I assume the car was running before you replaced the computer. If you still have the old computer try it on. This will help you determine if the problem isn't in the new computer. If you can't test as above, check for power to the distributor. If no power then check the circuit from the computer to the distributor (first the fuses that are marked "Engine Control" then the wires at the connector on both ends). If the circuit is OK then the computer is probably faulty.
If you get power then check the coil pack or the distributor. I don't have the wiring diagram for the 2002 Sentra but usually power to the pump is controlled by the distributor.Please feel free to let me know if I can help you more.

check fuel pump, fuel pump fuse, distributor,and ignition coil please. then you will need to check crank position sensor.(to do this you need to find factory service manual)
