Flywheels or flex plates ( manual or automatic)
flywheels will generally shatter the bell housing so It may be flex plates
They crack the center out from incorrect fitment of the washes at the crank shaft that makes them flex against the torque converter
generally it is the omission or the incorrect fitment of the large dish shaped washes or the flex plate not being turn around until all of the bolts screw all the way in finger tight
the units are make in thousands and last hundreds of thousands of miles so to have such a problem is lack of attention to detail on fitment or lack of trade skill in the fitting

SOURCE: Engine light is blinking and it runs very rough/low power in gear.

Check the coil pack. Same symptoms on mine. It went at 74,000.
You can get the resistance specs from a shop manual. I have been told the plastic engine cover traps heat and makes short life of the coil pack. I removed the top engin cover, cosmetic only after replacing mine. You will probably need spark plugs also they are probably fowled by now. If you have not changed spark plug wires in awhile in would not hurt.

Check your engine oil and break oil weather it is in below low level or full, if it has in low level get an engine oil for your car module and pour it. otherwise go to authorized Hyundai service centre and check for it.

unless you can discover what DTC (Diagnostic Trouble Code) has been recorded/set in the control module, it's anyone's guess.

Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Overchanging alternater (ECU?)


The ECU has no control on the voltage. Does your vehicle have a separate voltage regulator? If so that's your fault. A lot of alternators have the regulator built into them. The alternator needs to be put on a test rig away from the vehicle and the output tested, this will eliminate the vehicle, You could disconnect the wiring to the alternator, run three fly leads to the alternator and to a separate battery and run the engine and test the voltage on the spare battery. Wire 1: Battery neg to case of alternator Wire 2: Battery pos to + terminal on alt (the thick wire) Wire 3: Battery pos through a 5 watt bulb to the ind terminal (ignition light) 17 volt will blow another battery for sure.

I have put a new alternater, belt, and battery in my daughter's 1998 Hyundai Elantra and it still want hold a charge. As soon as we give it a jump then we try to move the car it cuts off. I don't know...


I would have the whole charging system tested with a Volt Meter before you change anything else. You can test the Alternator with a Volt Meter while the engine is running. The Alternator should be putting out between 13-14 volts, anything less and you have a bad Alternator. Check all Battery, Starter, Ground connections for loose or corroded wires and tighten or clean as needed.

You need to pull the starter out and check the drive gear. If the drive gear is no good you will have to replace the starter. Make sure the cogs on the fly wheel are okay. If the fly wheel is damaged you will have to replace the fly wheel.
