1999 GMC 3/4 ton ol pan


Asked by Lw1692 Feb 22, 2020 at 06:54 PM about the 1999 GMC C/K 2500 Series

Question type: General

I have a 1999 GMC 3/4 ton that won’t start.  I changed the plugs, wires and
fuel filter.  Then it started.  There is something on the bottom of the oil pan that
is attached to something in the vehicle by two wires.  The wires go off to a
harness and then off to something.  Can you tell me what it is?
