Replacing Fuel Distributor and Pressure Regulator

I measured the resistance across the two poles of the differential pressure regulator as you suggested.

You suggested that it should measure 200 ohms.  Mine measures 18 ohms.  Yes my meter is on the correct scale...on the Rx1 scale I read it as 18 ohms.  On the Rx10 its about 2 or close to 20 ohms.

Are you sure that you's is 200 ohms and not 20?
Are you sure that resistance is a reliable measure of whether its good or not?
Your system, the 87 4000 is a CIS-E.  Mine is a CIS-E-III.  Perhaps their resistances differ?

Okay good detective what's the Ohm value of the two screw thingy??

  I am leaning towards accepting the offer of a used CIS III-E repair kit that is known to be working from a member of this newsgroup at a very reasonable price.  However I wanted to review the situation, the investigations, in particular the results of today with those members that have offered assistance.
