a bad idle sensor control valve to start with or your egr valve has a vaccum leak
there is two main things that will cause an elantra to have no spark the ignition coil pack or the crankshaft sensor
mine did same, 95 elantra. it was fuse for radio in fuse box. hope that helps.
most likely the wheel bearings.
when ur car cutoff &it has to sit for 15 to 20min for it to start back up what cause that problem
timing belt snapped
Bad/shorted battery? (doesn't not hold a charge)
It could be the radiator is clogged. The thermostat could be bad (prevents the coolant from circulating from radiator to engine block)
Check your fuses. If they are all good and none are blows, you probably have a short somewhere in the electrical lines.
No, you installing a fuel pump has nothing to do with the fuel gauge
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
If a Hyundai Elantra stops running after an hour on a running speed temperature, it could be a bad thermostat. It is best to have a mechanic take a look at it to determine the exact cause.
its probably your TPS Switch or your idle control sensor, check engine light will not come on for either take to Hyundai dealership
