I know for a fact before I put the motor in we tested the oil pressure with the drill and was working. I have a new sending unit on it. I'm not sure what it can be. Also have an aftermarket rear sump with no oil pressure sensor on it.

Connect the 10 ohm resistor between ground and the sensor wire. The gauge should read max high. Connect the 75 ohm resistor between ground and the sensor wire. The gauge should read min low. You can do the same resistor test with the temp gauge. This test will tell you if the problem is with the sending unit or upstream. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>kuku93</b> <br /><small>Member # 14014</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2017,3,10,11,30,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I solved it.
