Hi,

Art is better positioned to answer this but I'll jump in. Your description of the operation of the injectors is my understanding as well, that is, they depend on ground at pin 18 and all open at the same time.

The injectors on my car will click quite audibly if manually grounded. The question is whether they are getting any ground from pin 18 of the ECU. I'm interested to see how the diagnostics test works.

Ken
