Spoony Posted May 29, 2008 Share Posted May 29, 2008 hi a friend tried to install an eu spec fuel pump in his facelift jspec. the eu pump starts for 2 seconds then stops. when he takes direct + and - from the batterie it works, when he puts back the jspec pump with the oem plugs it also works. do we have to make some changes with the pump harness?? what is the problem?? thanks Quote Link to comment Share on other sites More sharing options...
Jim_1979 Posted May 30, 2008 Share Posted May 30, 2008 Can you not just wire it so it's on a switched live feed? IE, not use the original connector? Quote Link to comment Share on other sites More sharing options...
Spoony Posted May 30, 2008 Author Share Posted May 30, 2008 yes we will do it, i just thought i ask before we do all the work Quote Link to comment Share on other sites More sharing options...
SimonB Posted May 30, 2008 Share Posted May 30, 2008 Can you not just wire it so it's on a switched live feed? IE, not use the original connector? Not a great idea, as the pump will then continue to run when the engine isn't. Like when you're upside down in a ditch and it's pumping fuel out into your hot engine bay...

Jim_1979 Posted May 30, 2008 Share Posted May 30, 2008 Ok... put a kill switch for it in the cabin. That way you can kill the pump off in the event of a crash? lol. Seriously... I don't know, but it would keep it running and solve your problem. Quote Link to comment Share on other sites More sharing options...
Spoony Posted May 31, 2008 Author Share Posted May 31, 2008 the trick is to use a relay with the oem + wire as a switch for on and off Quote Link to comment Share on other sites More sharing options...
