Testing OPS wires
I am trouble shooting a 0 oil pressure issue with my 02 Z06. Yesterday the oil pressure was fine, today 0.
Replaced the oil filter and OPS with no results. I want to test the wires leading to the OPS to rule this out next.
Its a 3 wire connector, ground, 5v, and voltage from sending unit correct?

I tested the ground, its ok.
Next I would attach my meter to the ground and grey wire, key to accesory and I should see 5 volts, right?

Key On - Grey wire has 5 volts - this is good
Key On - Tan wire has 0 volts - this is good
Ground is good
Tested OPS with compressed air and key on - Gauge moved
Looks like my pump is the cause
