Is this a catalytic converter problem, or something else?

I've got a 2000 Hyundai Accent, with an intermittent no-start problem. It will start if it's been sitting unused for a few hours, but if you try to start it multiple times in an hour or two, it won't. It usually takes 20 minutes to an hour to get it to start when these instances occur.



It started doing it a couple months ago, quite suddenly. It's not happening any more frequently now than when it started, but it is lately taking longer to start each time. I've tried to research the problem, but there are so many possibilities. The computer says that the catalytic converter needs replaced, and a speed sensor on the transmission is bad. My father in law thinks replacing them will fix it.



Could these two problems be causing the no-start? I don't want to spend a lot of money to get it "fixed" and still have the problem. I need to nail this on the first try.



How can I tell, without taking it to a shop, that this is the problem, is there any way?Is this a catalytic converter problem, or something else?
if you actually have a bad converter it will cause hard starting all the time not sometimes,once the stop up they don't clean them self out,so you may have another problem also,it could still have a bad converter on it,but that may not be the total cause of the problems your having with it right now,and a speed sensor will not cause it not to start,you have other issues with it,try checking the plugs and see what they look like in it,its possible they may need replacing,it does have problems but not all of them are caused by the converter,good luck with it.
thank you.

i think it is cuz the exhaust getting clogged up so causing it not to start
A speed sensor won't cause a car not to start (It shouldn't anyways). But I had an 86 Hyundai that had a similar problem and sure enough, the cat was plugged, then the car ran like new after replacing.Is this a catalytic converter problem, or something else?
might be catalytic, if it is you should be able to get a New one for FREE from dealer if car is has less than 8 yrs/80,000 miles. It is a federal warrenty on all catalytic converters for the USA market. I had to have mine replaced a couple weeks ago at GM.

you can disconnect the exhaust at the header and see if car runs well
