Oil pressure sensor most likely, THOUSANDS of posts on the subject.

Get a mechanical gauge and test it. There have been many cases of poor quality sending units out there. The other possibility is that when you replaced the oil pump you crushed the o-ring and it is not priming the oil pump.

Lots of stories here about the sensor lasting a day or less, especially is it's OVER-TORQUED (15 ft/lbs I believe is the spec). Hard to believe anyone would go through all the hassle of a new pump WITHOUT actually checking the pressure with a mechanical gauge.
