I don't think this is right... There is a splice on either side of
that connector. Wire #31 is split into 2 circuits (pins 1 and 8 on
that white connctor). On the other side each one of those circuits is
split again so that there are a total of 4 (one for each injector).
Perhaps those splices are messed up.
You can narrow it down by testing continuity between the terminal for
wire #31 on the injection relay socket, and pins 1 & 8 on that white
connector. Both should be close to 00.0. If they are, your high
resistance is somewhere in the injector harness.

I TRIED GETTING ANOTHER RELAY AT THE BOSCH CAR PARTS PLACE, THEY SAID
"no listing",(which is a familiar phrase), SO I WENT IN TO TRY AND MATCH
IT UP, AND WAS UNSUCCESSFUL. THEY EVEN LOOKED THROUGH THE BOOK. THERE
WAS A PROBLEM GETTING A <2 X 15> AMP

Hmmm, interesting. You should be getting continuity through the
relay. Even Peugeot's diagnostic test relies on that. Do you have
another injection relay you could test and try out?
The ignition relay is constructed the same way--try performing the
exact same test on it--relay pins for wires #2R and 32J should show
00.0 ohms.

Huh? This does not make any sense. You should be reading 00.0 ohms
between one injector connector and one outer pin on the resistor
harness. Just out of curiosity, you performed this test with the
resistors disconnected, correct?
**** YES, I TESTED THIS WITH THE RESISTOR PACK DISCONNECTED, AND THE
FIRST THREE OUTER TERMINALS WERE THE ~2.5 OHMS NUMBER, BUT THE FOURTH
OUTER ONE WAS .0L m OHMS
If so, and if I am interpreting you correctly, it sounds like a
harness has been damaged somehow, affecting multiple wires. Carefully
check the injector harness that runs along the fuel rail. The 4
injectors and the aux air device are all a part of this little sub-
harness and the connection point is that white connector.
**** I INSPECTED THE INJECTION HARNESS THE BEST I COULD (visual). I CAN
SEE WHERE THE WIRES SPLIT OFF, AND FROM THE OUTSIDE, LOOKS TO BE INTACT.
I have more info for you... Don't give up!
