Help! No oil pressure!

[Gregory OConnor]

Ryan, you may want to check ohms into the harness at idle from the
sensor and ohms out of the harness at idle at the dash to see that
they match. if not that may prove a wire issue and not a hard part.

I remember Leroy wrestling with the sender and gauge not matching
signal so that is also a point to consider if you just replace one
or the other part.

I wonder if someting as simple as teflon tape could prove issue in
reading, would a 'removal and cleaning' of the sender (RalphF
montra) not be a prudent first step.
