How do i check the transmission fluid in a manual 99 Hyundai Accent?
disconnect the battery for about 30 sec then reconnect it
Probably need to check the crank sensor (if the check engine light is on) or the fuel pump... I had that problem not too long ago...
go to your Hyundai dealer and make it check
To test the water pump on a 2001 Hyundai Accent, first, inspect for any visible leaks around the pump and check for any unusual noises while the engine is running. Next, ensure the engine is cool, then remove the radiator cap and start the engine; observe the coolant flow in the radiator. If there is no flow or the pump appears to be leaking, it may indicate a faulty water pump. Additionally, you can check for excessive play in the pump's pulley, which can also indicate wear or failure.

how to improve a weak motor on a 2000 Hyundai accent These engines are very prone to losing power if the plugs are not gapped correctly. So, if you have 100,000 miles or so on the engine start with new plugs. As you remove the old plugs check them to see if they are a clean grey color indicating that they are firing correctly. If the plug is black it means you have a bad wire or coil to that plug. Good luck
because you are one alot of ol timers call the check engine light and idiot light
A blinking or flashing check engine light in any Hyundai is indicative of a misfire taking place. It could be due to a faulty ignition.coil, leaky ignition wires or bad or worn spark plugs.
When my check engine light comes on, it is caused by the temperature sensor not working. As soon as the light comes on, my temperature drops to cool. If the light goes out, the temp gauge returns to normal.
