OK,
I hooked up a pig-tail to this injector. Then I got a 9V battery and tapped the pig-tail numerous times. I never hear the injector click - and I'm assuming that it should. The pig-tail does spark though - as if there is a short - which seems odd. So, what is that telling me? BTW - PO has said that all the injectors were cleaned and tested and all tested and sprayed well. They were however sitting in a baggy for three months. I can't imagine that they just went south???? All four injectors and the cold start valve all behave the same way. Thanks, Len  Attached thumbnail(s)

They are obviously stuck closed. Send them in for pro cleaning.

QUOTE(Jeff Bowlsby @ Aug 12 2013, 03:59 PM)  They are obviously stuck closed. Send them in for pro cleaning. German Car + German Owner = Stubborn Situation (IMG:style_emoticons/default/smile.gif) The part I'm hung up on is they were just cleaned six months ago - so I would think that soaking them in decent cleaner would be an easy fix. I most likely will end up sending them in for professional cleaning. I already contacted Rich at Cruzin Performance - he's out all week, so it don't matter if I ship them today or Friday... Until then, can't hurt to keep trying. |
