Possible cause is the crankshaft position sensor if you have a bad alternator then your battery can drain while the car is running DOn't know when did you changed cables lately but arching on one of them will do that. Check the cables for any damage or wear. Also look at distributor while you're there.
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.
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
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
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)
Most likely your thermostat is bad. If you are not getting heat it is stuck open. If it sticks closed, your engine will overheat and be ruined. I would replace the thermostat A.S.A.P.
It's supposed to run, even with the key off until the radiator is cool. If it never stops you've probably got a bad temp. sensor switch.
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
