Tekira Posted March 21, 2004 Share Posted March 21, 2004 Hi, Sorry about all the posts but if the fuel pump doesn't work i cant drive. I got a new eletric pump For my 74 260 and installed it today. i hooked up the wires and the pump doesn't even turn on, no power. The problem is that the lead wire, 12 volt power source, is not connected to a 12 volt power source. The wire from the pump to the body harness is connected, but after that i have no idea where that wire goes. i do have a wiring diagram but i cannot follow it. I need to know what powers the line to the fuel pump and where its is connected. Is it on the fuse box. or can i just run a line from the pump to a 12 volt power source, need a list of items with a 12 volt power soucre. I need help badly and i have had justt about all i can take of that wireing diagram. Thx, Josh. Quote Link to comment Share on other sites More sharing options...

spotfitz Posted March 23, 2004 Share Posted March 23, 2004 It appears you have an early 260Z(As I do), so the electric pump works off of a relay(ignition relay actually) which is located on a bracket just above the passenger kick panel under the dash. More then likely replacing this relay will fix the problem, but I would suggest you find a known good one to try before forking over the dough, if possible. If it is a "have to get home to feed the kids" type of thing, you can run a "hot" wire from a fuse that is powered by the key being in the "on" position. I would not use this as a perminent fix since this eliminates the relay which shuts power off to the pump in the event of an accident. This ofcourse helps keep you from having a crispy Z and possibly a crispy body. Hope it helps. Quote Link to comment Share on other sites More sharing options...
