Mechanical oil pressure gauge sender location

[GSX455]

So, I had no oil pressure, had good oil level, truck ran fine, 2001 24 V.  I replaced the oil pressure sender under the wiring harness.  I still have no oil pressure showing on the dash cluster.   Could it be a bad sender, or a bad gauge on the dash?   I'm throwing no DTC or error codes on an INOVA code reader.  I bought a mechanical, Autometer oil pressure gauge.  Can I locate the sending unit on the oil filter housing, or is there a better place?  I searched all of the other  posts on the forum, and no one has had the problem of replacing the sender and still having no oil pressure.

Thanks!

First of test your cluster and see if it is damage or throwing errors.

Second there is a plug on top of the oil filter mount. You can add a oil pressure gauge there for testing or permanent. The actually oil pressure sender is typically right near the ECM on the driver side of the block. 3 pin plug.

So, I did the gauge cluster test, and the oil pressure gauge responded in the actuator test.  Does this mean the oil pressure sender I bought is faulty, replaced about 2 years ago from Geno's Garage ?   Could it be a bad wiring harness?   The 3 pin plug on the sensor below the ECM is snugged in there pretty well.

Thanks!
