That's the ignition module in post #10. The fuel pumps are self priming, it just takes a little time to start it when the tank is empty.

Ok so the unit in post 10 is the ignition control module I was having a hell of a time locating it on the repair manual i downloaded from xenons30 site

Maybe after work today ill spend a bit of time and figure it out

Nissan calls it a 'transistor ignition unit'. If you have the 76 manual, look on pages EE-33 through EE-38 in the Engine Electrical System section.

Ok great thanks ya i have the zipfile on my comp but the terminoligy through me thanks for the info

the transistor ignition unit is located on the interior relay bracket just above the fuse box.
