No one is going to be able to answer this question without a lot more
information.

When you say it wont start, does that mean that the engine turns over
when the starter is engaged but never fires up?

Or does that mean that the starter does not turn the engine over at
all.

Barring catastrophic mechanical failure (which you surely would have
noticed, right, any loud crunching noises from under the hood?) there
are only two system failures that can keep the car from starting, fuel
and ignition.  That's where diagnosis starts.  You can have fuel
pressure checked. You can check for spark.

Apply basic scientific analysis to your problem and you are much more
likely to have good results than you are by asking a bunch of
strangers on a Usenet group.

Now, if you can come back with a list of things you tried,
systematically, and post the results, one of the knowledgeable persons
that read this group may be able to help you.

Unfortunately, it can be a dozen things right out of the chute without
even thinking about it and we don't have enough information to tell you
which to try first.
Go to www.tegger.com and follow the no start condition. See how well
you can describe what is happening to your car and post your findings.

Are you using a key?  Is it the right key?  Are you turning the key to the
start postion?  Does the car have a battery?  Is the battery connected?
Does the battery have a charge?  Does the car have gas?  Is it the right
type of gas?

As Elle, says, start with TeGGeR's FAQ site.
http://tegger.com/hondafaq/faq.html#startrun will take you a long way. Of
course, we are assuming the timing belt is not overdue for change.
