The entire engine has to be lifted enough to remove the oil pan. I would get an aftermarket gauge to test before I went to replacing the pump.

There should be a sending unit for the stock gauge and put your new gauge there.I think its on the driver side toward the front of the motor.I could be wrong though

Yea driver side front right behind timing cover. If you losing pressure completely while you have oil pan down to check pump check your bearings as well. When that happened to me. I checked my bearings only after I bought new oil pump and come to find out every bearing in the motor was shot. Easy tell tell if bearings are shot is when you drain your oil check for any metal flakes in oil. But that doesnt alway say for sure. Until you check

Never trust the factory oil gauge. Grab a mechanical one from advanced which is around 20 bucks I think, that will tell you exactly what psi your running at.

Re: Oil pressure guage

When the oil pressure drops as the engine warms up it is usually a sign of worn bearings.The farther it drops the worse the wear is.
I have seen engines with bearings so worn out that the oil pressure would drop to zero at a stop light when the engine was at operating temperature.


If your pressure climbs when the RPMs increase, then it is likely that your oil pump is ok and worn bearings are the issue.

Like the guys have said get a mechanical gauge and check it first as the stock electrical gauge and sending unit may be the culprit. Fingers crossed.
