I have a 99 Ranger with the 4 cyl engine and the oil pressure guage drops to 0 psi once in a while. It is like the power to the sender is shut off. I'm sure it's not the oil pump. Where is the oil pressure sender located?
Thanks for any help, Bob

 

Back of the head on the drivers side. It's the biggest sensor there cant miss it.

 

Thanks for the help.
