I changed my water pump and timing belt on my 01 tuburon 2.0 and now my car wont start? Please help!

hi there i would probably be giving it a compression check to start with , if it has over heated it may have blown a head gasket and now has no compression.

The previous solution to check the idle air contol is in the correct area but needs some clarification.
The idle control is accomplished by two parts: Throttle position sensor ( $35 at Autozone) and idle contol valve approx $190. I replaced the throttle position sensor about a week ago and it runs perfect
to date but am a skeptic after almost two years of dealer incompetance. I researched all the sensors and failure symptoms on the internet and the throttle position sensor failure symptoms matched mine
exactly. See http://wiki.seloc.org/a/Throttle _Position_Sensor

SOURCE: Do I change water pump when having timing belt changed

I would go to auto zone and get a diagram and the timing belt and do it yourself and the water pump (no it does not have to be changed everytime the timing belt is changed but if the car has over 60,000miles then it is best to change them both) it is not that hard especially if the car is not out of time just make sure you disconnect the negative side of the battery

SOURCE: do you have to change the timing belt when changing water pump

Yes thats correct the if the water pump goes so goes the timing belt even if it looks good. The timing belt is only good for 50,000 miles if you have more this then you got your moneys worth.

Hi there. I can solve this dangerous problem you are having. You would loose acceleration at lights and intersections, the engine will shake and revs can go crazy. The issue is the MAF (mass air flow) sensor. It was recalled in 2001 as a safety problem as people died driving this model of sonata. If you connect your comp up to a diagnostic machine you will find its the MAF the problem is a problem that is hard to ctah on a diagnostic machine though as it comes and goes. You will need to replace the MAF ASAP as you can die from this fault and hyundai will not care due to the age of this car.
