Re: engine skipps at start then clears up
You my friend need a head gasket. Coolant gets into the cylinder and it washes out your plug, resulting in misfire on first start up. Once the coolant burns off, it will run fine. Headgasket issue. I have done quiete a few of those on a Sentra.

If you are sure you have a spark to at least half of the plugs, and there is no reason to suspect that the engine was being used abnormally just before it was shut down then it is most likely flooded or you ran out of gas.
Black smoke from the tailpipe indicates that the engine is getting a fuel mixture abnormally high in fuel (flooding). White smoke generally indicates not enough fuel.
Unless your engine is damaged or the timing changed, your engine will run if it has the following: proper fuel mixture, air, a spark to at least half of the spark plugs, and compression.
For a "flooded" engine there are two routes. Wait until the excess fuel has had time to dissipate or hold the accelerator to the floor while attempting to start. Be prepared to let off the accelerator about halfway as soon as it starts. And then down to about 1500 rpm. You do not want to over rev the engine. But holding it at about 1500 rpms for about 3-5 seconds will help flush out any excess fuel. You can then slowly return it to idle speed.
If you have the second ignition key's with you try it. If not try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help.
Sometimes if the gas cap is open while the car runs, the Check Engine Light turns on. This is common and happens on many vehicles. Try unplugging the negative part of your battery, let it sit for 10 minutes, then plug it back in and start the vehicle up. Most of the time the check engine light will disappear. If it persists, you might have to get a mechanic to clear the code and settle your check engine light.
