Question about 1999 Buick Regal
Actually not that hard, but it does require some tools. Normally you will find the fuel rail fastened down in some manner on top of the fuel injectors along that side of the engine. First step is to find the relief valve (looks like a tire valve), be warned that fuel will be under some pressure when you push this valve, do not do this on a hot or warm engine and put a rag around the valve to catch excess fuel.
Remove the fuel rail, then carefully unplug the wiring connector on the # 1 cylinder fuel injector. The injector should come out with a good firm tug, make sure that any O-ring has not been left inside the injector seating area. Place a single drop of oil on the new injector's O-ring and push it into place. Replace the electrical connector, then the fuel rail. Turn on the ignition, but do not start yet - check for any fuel leaks. If none, then start the engine and you should be good to go.
