Re: [DML] Re: Fuel pump not working



Thanks for all your help.  I figured it out Sunday afternoon.  It turned out to be something simple.  The button on the inertia switch was in the up position so I pressed it down and the fuel pump worked.  I figured it was something to do with the ground to the fuel pump since the I was getting voltage from the brown wire on the RPM relay socket.  Looks like the PO had fuel pump issues as he ran wire underneath the car from the battery to the fuel pump.  He also cut the white/purple wire at the RPM relay socket.

If it turns out to be a wiring problem two of the more common things that go wrong is 1) A PO that did some "creative" wiring to get the pump to run because he did not understand the circuit and the purpose of the inertia switch and 2) the multi plug up inside the washer bottle area gets corroded. The fuel pump power and ground go through that plug. While you are working on the fuel pump circuit you may as well make sure the inertia switch has been moved to the side of the footwell and off of the Lamda counter and that the switch has a splotch of white paint on it indicating it has been replaced. Before "digging" for the multi connector verify presence (or confirm absence) of power and ground at the fuel pump.
