First, are you getting any knocking or ticking from the engine? Also, I recommend checking the oil pressure with a mechanical gauge. Most parts stores will lend or rent them. All you do is remove the new oil sending unit you installed and screw in the mechanical gauge. That way you will know if you have good pressure or if there are internal engine problems. Finally, if the pressure is good and you have confirmed it and the wiring from the sending unit is good, chances are the gauge is bad.

Let me know if you have other questions or need additional help.

Thank you for using 2carpros.com, and I wish both you and your family a happy holiday.
