ba6 not pumping

[Mulcheese]

The pump bench tests fine. So now I am lost as what to do.

The pump worked fine about 2 years ago and the heater warmed great and then last fall it wouldnt start up. I decided to dig in to it this deeper the other day. I pulled off the entire heater and guess what? A mouse house. I cleaned all the crap and insulation out visually inspected everything and istalled. Still no volts to the pump.

What I have tested. All fuses are good. With the heater lever slid over the blower relay switchs on, the combustion blower turns on, (points have been cleaned), the glowplug ignites, the circultion blower turns on, and still no power to the pump.

In the bentley it shows individual relays in holder for ..... fuel pump. Are these in the back of the fuse panel and which one is it?

Can you scare up a schematic? If the wiring is intact, follow it from the pump backwards to its relay. The generic relay nomenclature should have:
voltage to #30,
continuity from 87 to the pump (+)
good ground #85
#86 is the control wire that tells the pump it may turn on. Who tells it that it is OK to turn on? Me not know.

Thanks for the response Colin. I have HEAT. After locating many manuals and many searches I was directed to another set of points in the combustion blower. I gapped them and off we go.
