Cartesian Posted November 14, 2008 Share Posted November 14, 2008 Hi I'm kind of new at working on cars so sorry if this question seems dense, but I'm trying to change the fuel pump on my 280zx and I'm having a problem with the wiring. At the place they connect to the pump itself, the wires seem to be stuk on with molded plastic. Its very hard and I can't seem to cut through it. To anyone else who has changed the fuel pump on at 280zx, how do you get around this? Melting them off seems like a terribly bad idea; what about cutting the wires themselves? My new fuel pump came with connectors, so I guess I could just connect them to the cut ends of the wires but that seems, well, wasteful. Any advice?

Ferrariferg Posted November 14, 2008 Share Posted November 14, 2008 Just replaced mine a few days ago. The plastic comes off with a wire wheel. If you have a compressor and a die grinder with a wire wheel that works just fine. After you get the plastic off there are just a couple 12mm or 10mm nuts. I would also check ebay for a pump. The auto parts will just sell you an over priced universal pump that doesn't work right unless you splice extensions to your electrical and it wont fit in the pump bracket unless you get longer fuel lines. Hope this helps. Quote Link to comment Share on other sites More sharing options...

smokeybear454 Posted December 12, 2008 Share Posted December 12, 2008 There's a connection just inside the car through the rubber piece. I took my fuel pump off and the connection fits through the hole but not with the rubber piece still in there. Quote Link to comment Share on other sites More sharing options...
slownrusty Posted December 12, 2008 Share Posted December 12, 2008 Please do not cut the factory connectors!! If you have a Dremel with a small wire wheel then use it to remove the coating. The coating is obviously there to protect against moisture and the elements. Then use some sandpaper to clean up the factory brass connectors before installing the new fuel pump.

Cartesian Posted January 11, 2009 Author Share Posted January 11, 2009 Well, the engine started dying again. It always starts up cold but if I get to operating temperature I risk just having the engine lose all power during idle. Then I have to crank it several times and pump the gas pedal to get it going. This is pretty much what was happening before my old pump failed. Could there be any other reasons for this besides my fuel pump? Quote Link to comment Share on other sites More sharing options...
