yes Andrew

Re: Map sensor or lack of?
 

I saw the voltage of 0.771v at the ECU. it is quite low for the MAP sensor. It should be around 1.5v at pre-crank. Also check the continuity of the blue wire of the grey harness because the the same voltage was not appearing the the RJ connector.

yes the continuity has been checked the voltage is not making it from one end to the other. how else am I supposed to check it?

I suppose you can use the resistance option on the Fluke to probe the the two ends on the the blue wire. It should be near 0 ohms. One end on the gold figure of the RJ. May need to sharpen your probe.
