I just changed the oil on my son's 1998 Cherokee Sport. All went well. When we started the engine the "Check Guages" light came on. Also it is not registering any oil pressure. The Jeep runs fine. I tried the turn engine to on position and depress the accelorator three time trick with no success. we don't have an owners manual. Any suggestions?

 

Did you put oil back in it?? Takes a few seconds to build pressure or more likely you knocked the sensor when you were pulling the filter.
