Question
Thanks for your answer.  How do I check for trouble codes in the EMC?  Is that something I can do without taking it to the dealer or mechanic?
Thanks.

I have a 2002 Hyundai Accent with just over 92K miles.  Lately I have been having problems starting the car.  It will just crank and crank, but not start.  We tried jumpstarting which does not work.  Right after that it started when we pushed it and popped the clutch.  This problem seems to be intermittent and the repair shop could not get the problem to occur when the looked at it so they could not do anything.  It runs fine when it does finally start.  Do you have any idea what the problem could be?
Thanks.

Answer -
With the information you've given, there's a large realm of possibilities.  Anything that could keep the fuel management system from operating could be the issue.  The crank sensor is probably the most likely culprit, but there are so many other possibilities that taking that guess still has a low percentage of fixing your problem.

The fact that the car started with the clutch is likely nothing more than a coincidence.  Turning the engine with the starter or with the transmission ultimately has the same effect.  

If you've verified that the battery and charging system are in good condition (which they probably are based on your description), the next step is to check for trouble codes in the ECM (engine control module).  If there are none and all the ECM data values appear normal, then there's not much to do until the problem reoccurs.  

If the shop can test the car while the problem is occurring, they should be able to test and locate the issue.  One of the things you can do when the problem occurs is to check to see if the check engine lamp illuminiates when you turn the key to the "on" position.  It should come on for at least a few seconds when you do this so you know that the lamp itself is working.  If it doesn't come on, that's a signal that the ECM isn't powering up properly.  Beyond that, there's probably little you can do to pinpoint the issue unless you're capable of checking for spark and injector pulse on your own.

Answer
Some places such as AutoZone advertise that they'll check for trouble codes for free.  Beyond that, a repair shop would need to check for codes.  Since the car was already in the repair shop, I'd first call them and ask if they checked for trouble codes when it was there.  It's possible they checked and there weren't any.
