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)
