Based on similar problems I've read about with these, I would try the crank position sensor first. If that doesn't work, it's probably the ECM...

I'm tempted to say it's just got the blues.
If it happened all at once, it's probably a fault in the primary circuit, that is, the low voltage that feeds the coil. Possibly a bad ground, blown fuse, broken wire or something like that.
This could be a good opportunity to learn. First be safe! If you get a Haynes manual it will have some safety precautions in there, such as always wearing eye protection, keeping your hands away from moving parts and not crawling under a vehicle unless it is safely supported.
There will be a troubleshooting guide in there with a series of checks to help you zero in on the problem.
Be careful when you go looking for spark, it sometimes hurts when you find it!

At this point, go with the probabilities. That means finding out what problems your particular model car tends to have that create a no spark condition. Some could be fixed without access to professional tools. Maybe the crank sensor. Your ECM computer monitors all the sensors and generates the ignition triggers. So check on the internet for similar owner complaints and service bulletins.

A bad crank position sensor or blown ECM. A good mechanic can tell if the CPS is putting out a signal in two minutes.
You don't have a defective alarm system in there, do you?

I would first check the distributor cap,rotor and secondary wiring.Many no spark conditions can be traced to the secondary ignition system.Check for loose wires and corrosion at the distributor cap and ignition coil.Make sure the secondary wiring is tight in the cap and coil(especially the coil wire)Remove the distributor cap and examine the cap and rotor for cracks or carbon tracking.Examine the center carbon button for chips and spring tension,and look corrosion on the inner terninals.

Yes and no.
The thing is if you have to ask that, you don't have the knoweledge to go further than you have. You have identified the reason for a crank but no start but you probably won't be able to locate the cause without the tools and knowledge.

it could be the crank sensor,a bad module or coil pack.

chk your temperature sensor to see if it is cracked.
