Have a 2001 Hyundai tiburon that won't start. Battery was replaced in July when had same problem and mechanic says clutch starter circuit switch needs to be replaced. Is this a legitimate diagnosis? Or just the response from someone who doesn't know? Otherwise car runs fine. Clutch was replaced 1 1/2 years ago.

SOURCE: Immobiliser ?????? so i have been told

If, when you switch the ignition on, you get a dash light on, the symbol is a car with a key overlaid, you have somehow activated the immobilser You could try disconnecting and reconnecting the battery, this may reset the immobiliser, If this does not work you will have to contact a Hyundai dealer to get the immobiliser unlock code.

SOURCE: Tools needed for replacing 2001 Hyundai Tiburon CV joints.

CV joints are not hard if you do some research. Get a shop manual first. You will need a good jack, two jack stands. I am not that fam. with the Hyundai, but some fwd cars have med/ large bearing retaining bolts so you will need 1/2 drive socket set up to say 33 mm. You will need a whole day or 2 to do this. set aside that much time in case of some road block. You have to pull both wheels and fender wells. On some cars you will have to pull the struts or the lower arms that hold them to the body to give room to pull out the cv assy. Do one at the time on some fwd's if you pull both the ring gears can fall out of sync and thats not good. Buy the complete cv axel rebuilt if you can. Work slow, take pictures as you go, be careful.

Hello mpolci...The 2003 Tiburon was sold to the public with a defective clutch, it failed due to warpage and bad pressure plate... among other things. There are MANY class action lawsuits. Did you resurface or replace the flywheel when the clutch was replaced? Did you go with an aftermarket clutch kit, or factory? Also the slave cylinder on the 03 was known to have a defective valve.
You can try checking the levels and bleeding the system and if you still have problems, then it could be a release bearing, a loose clutch pad, or a broken pressure plate spring....If the clutch is still under warranty, i would return it to the installer.
Good luck, i hope this helps...please rate me a fixya.

SOURCE: overheat 2001 hyundai tiburon

Only 2 parts remaining are the thermostat and waterpump. Always start with the thermostat when diagnosing an overheating problem. If the car is overheating constantly under all conditions and coolant is backing up into the reservoir, it's very likely to be the thermostat. If it only overheats at low speed or idling, it's more likely the waterpump.
