celica isnt starting sometimes. Options

[KOWABUNGA]

my buddy just picked up a 1994 celica st just before winter hit. he planned on using it as a winter beater. lately it hasnt been starting up right away. it doesnt crank or anything. but then 10 minutes later it will start right up. he replaced the battery with a brand new one, and replaced the alternator and belt but its still not starting on somedays.

anyone have any idea on what could be causing this to happen?

like i said, it doesnt crank over when the key is turned, but all electrical devices work fine. we wait about 10 minutes and it starts right up without a problem.

he said it could be the cold weather, but my celica doesnt have any problems in the winter.

anyone have a clue???

How does it run after it starts up? Constant idle or does it rise and fall a few hundreds rpms?
It doesn't sound like a starter to me, because it seems to be an intermittent problem. Which leads me to believe its either in your grounds, plugs, plug wires, distributor rotor, or loose connections at coil or igniter.. I would check in pretty much that order.
