Symptoms bad fuel injector - Accent Hyundai Cars & Trucks

SOURCE: symptoms bad fuel injector,

If your fuel injection system has a fuel rail to deliver fuel to the injectors, you will have to remove it before you can remove the injectors.
First disconnect the fuel line at the end of the fuel rail. If there is another lune at the other end remove it too. (always be careful, some of these lines are under pressure).
Remove the screws or bolts which ever is holding the rail in place, if the wiring travels over the rail disconnect it first.
With everything disconnected, pull the rail away from the injectors. Most of the rails are just pressed on to the top of the injector tops, once you've removed the screws the rail should come off easily.
If your vehicle doesn't have a fuel rail then you have to disconnect the clips to each injector. Each injector will have a clip either at the top or at the top on the side that connects to the wire harness. Most fuel injector wiring plugs are held in place by a springy wir. To remove this wire, put a flat head screwdriver between the wire spring and the clip and CAREFULLY pull it away (don't loose it).
With everything off, you are are ready to remove the injectors (it is recommended that you use an injector puller) it is important that you don't break anything or let dirt and debri fall inside of the port wholes of the engine.
With the injector puller you just slide it under the injector and pop it right out.
To put the new injectors in just do the same as removing the in reverse. Remember to be careful and don't force anything.

I hope this helps for you.
