Guest caralva Posted June 24, 2004 Share Posted June 24, 2004 HI Guys! Im a newbie to the post and i need some help!!! I recently purchased a 78 280z 2+2 the car of my dreams, but its not running the guy told me it had a fuel delivery problem and that he thought it could be the pump. Can anyone outhere tell me of a quick way to test the pump, or what other tests i should do to diagnose the fuel problem? Thanks!!! Quote Link to comment Share on other sites More sharing options...
z-REX Posted June 24, 2004 Share Posted June 24, 2004 DISCLAIMER this may not be the safest but.... pull your fuel pump. run a line into a gas can, wire to a good ground, and touch a hot line to your car battery. if you get gas flying out, it's good. oh. and no smoking!!!!

datsunlover Posted June 24, 2004 Share Posted June 24, 2004 Yah.. actually, that's what I would do.. it's easy enough, and cost is like $.50 in fuel! Could just be a clogged fuel filter too, which is something I would change anyway after just purchasing the car. Good luck, and do be carefull!

Clifton Posted June 25, 2004 Share Posted June 25, 2004 Fuel pumps are rated by gal/hr. The best way is to pull the return line off after the regulator. You need to check fuel pressure still but this way you can measure the volume at 36 psi and above and know how much power your pump can supply fuel for. A stop watch and gas jug is all you need. some stock pumps won't put out moe than 50 psi though. Quote Link to comment Share on other sites More sharing options...
Guest caralva Posted July 2, 2004 Share Posted July 2, 2004 Thanks for the help guys! I appreciate it greatly! But is there a way to check it with a multimeter? Thanks Los Quote Link to comment Share on other sites More sharing options...
Clifton Posted July 2, 2004 Share Posted July 2, 2004 Yes, check the power at the pump. If it has power remove a fuel line. There should be pressure, enough to spray you so be carefull. Quote Link to comment Share on other sites More sharing options...
