Re: Zero Oil Pressure @ idle but ok when over 2000 rpm's
Most likely it is just your sending unit, it is a fairly common problem with these Jeeps.
I had one fail on my 2000 Laredo 4.7 years ago. It is fairly easy to change out, I do not remember the size socket, maybe someone else can chime in with that.
I do remember that it took me longer to figure out the latch on the electric plug on the sending unit than it took to actually unscrew it and screw the new one in.
It is located just above the oil filter and it would be best to remove the oil filter and get it out of the way before you change the sender.
As long as you have plenty of oil and you are not hearing knocking when the pressure drops, it's probably your sending unit.
