I would think that if THAT side of the relay is bad, the van wouldnt run
at all, instead of being hard to start.  The AFM/relay circuit you are
testing is what runs the fuel pump while the van engine is running.
Since you have 2 vans, I would exchange the relay and see what happens,
test both vans.  Exchange the AFM also.  If your pump is not running as
you describe, then it could be the relay, AFM, ECU, pump, wiring, or
other components such as ignition switch; hard to tell without more info.

I  turned the key to "start", and then manually moved the AFM sweep arm to see if the fuel pump turned on---it does NOT click on and cycle fuel through the injector loop as it does in the good running '81.  Pray tell, what gives?  Is the problem my dual relay?  Thanks all in advance for your help.
