HOLLAATYABOYY1 Posted March 9, 2018 Share Posted March 9, 2018 (edited) 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 Edited March 9, 2018 by HOLLAATYABOYY1 Added info Quote Link to comment Share on other sites More sharing options...

SleeperZ Posted March 9, 2018 Share Posted March 9, 2018 (edited) 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. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 9, 2018 Share Posted March 9, 2018 Hmm, didn't know that. I thought my 1978 280Z did that, but it's been a long time since I ran the factory computer. Quote Link to comment Share on other sites More sharing options...

NewZed Posted March 9, 2018 Share Posted March 9, 2018 There are several sites out there that have FSM's free for download. Xenonzcar, nicoclub and classiczcars.com. The wire is small and just pulls off by hand. Quote Link to comment Share on other sites More sharing options...
