| + | * To prevent spray of fuel, purge system of high-pressure fuel before supply line is disconnected. \\ Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. | ||
| + | - Remove left side cover. | ||
| + | - Remove fuel pump connector from ECM caddy cover. | ||
| + | - Unplug fuel pump connector. | ||
| + | - Start engine and allow vehicle to run. | ||
| + | - When engine stalls, operate starter for 3 seconds to remove any remaining fuel from fuel hose. | ||
| + | - Shut off ignition. | ||
| + | Pulling the injectors is pretty easy once you have the above done. \\ | ||
| + | Then,\\ | ||
| + | - Remove the bracket from the intake manifold. | ||
| + | - Disconnect the electrical connectors from the injectors (there are two, one to each injector). | ||
| + | - Gently rock the fuel rail back and forth to remove the rail and injectors (not too gently). | ||
| + | - Pull the injectors from the fuel rail. | ||
| + | Once you have the injectors out, you can use a trickle charger for the 12v power supply. \\ | ||
| + | Cleaning the injectors: \\ | ||
| + | - Find the correct size holder for the injectors. | ||
| + | - Push the injector all the way into the holder. | ||
| + | - Connect the power lead to the injector (not to the battery yet). | ||
| + | - Connect one end of the power lead to the 12v source (trickle charger in this case). | ||
| + | - Put the holder onto the carb cleaner can and pressurize it (keep a hold of the injector too). | ||
| + | - Energize the injector and watch it spray across the room and go from a tiny amount to much larger as it gets clean. \\ Only used pulses of power. Do not leave it connected. | ||
| + | - Remove power, release pressure on the injector holder. | ||
| + | - Remove the injector from the holder, reverse it and do it all again, then reverse it again. | ||
| + | - Do the same to the other injector. \\ Put it all back together (as long as your O-rings are still good) and enjoy! | ||
