Priming fuel pump

Recommended Posts

I tried doing a search with no clear cut answer.  Does anyone have a write up on how to purge the fuel lines  in order to remedy a no start issue from empty tank? I want to try this before I start changing pumps and filters.    1976 280z

 

thanks

Purge the lines of what?  The EFI is self priming, you just cycle the ignition a few times.  The pump will run for a few seconds after turning the key on, turn it off and do it again until you can hear the lines pressure up and you are good to go.

The 1976 280Z doesn't have the priming feature.  It came on the later year 280ZX's.  And often doesn't work, after all of these years.

 

Take the small wire off of the solenoid and turn the key to Start.  The pump will run but the engine won't turn over.  It's described in the Engine Fuel chapter of the FSM.
