Car on blocks...
I put gas to the fuel rail today and one of the injectors is not working. Any suggestions on getting one unclogged? I guess I need to swap them around and make sure it it the injector. |

I suspect it is just dirty or varished.
How do you do the 9 volt thing? |

Only pulse it. Put a hose on it and blow through as you connect the battery. You may be able to clear it if clogged. You might have to blow backward through it. You can try soaking in lacquer thinner before you blow or send them out to be cleaned. |

(IMG:style_emoticons/default/agree.gif) Just my two cents worth on some successes I've had. I use a battery charger (don't use your car battery, too much current too easy to arc and spark), never thought of using a 9V, I'll keep that in mind. Also, I use brake cleaner and fill up the injector, pulse it with battery while using compressed air (I use about 30 psi) on the fuel inlet side. Repeat several times. If you put a paper towel under the injector you might be amazed to see the garbage that can come out. Certainly not professional cleaning but I've revived injectors on various cars and noticed improved performance. |
