Guest znow white Posted September 9, 2005 Share Posted September 9, 2005 i burned my fuel pump during my turbo swap i had the blue/red (gettin power12 v switched) for 5 secs and turns off . this wire is running to the positive on fuel pump which was green. my ground is black wire on ignition plug the one farthest from the green wire on the schematic in the haynes manual it would be bottom right. now i did some research and it says i only run that black wire if using the modulator ?! what is that? if im not using the modulator where do i ground it to is the battery fine? I have already ordered a better flowing pump AND I DONT WANT TO BURN THIS. So how do you guys who have done this swap have it wired . i just want to run this thing I have been working all summer on it and now school has started ....you get the idea.. thanks Quote Link to comment Share on other sites More sharing options...
260ZRED Posted September 9, 2005 Share Posted September 9, 2005 I am not using any modulator. Just look @ you wire diagram there should be a wire coming out of the fuel pump relay that goes straight to the + of the pump. The - of the pump should be connected to a good ground, mine is connected directly to the - terminal of my battery. You can always wire it on an off/on switch but it's better to use a relay like the factory does. Quote Link to comment Share on other sites More sharing options...
Guest znow white Posted September 9, 2005 Share Posted September 9, 2005 hey 260zred thanks for the response, so you have not run into any sort of issues with grounding to the battery like shorts or others electrical problems? I just want to be 100% so i dont burn the new fuel pump any other zedders or yankeeZ (i say with love haha) would like to chime in Quote Link to comment Share on other sites More sharing options...
evildky Posted September 9, 2005 Share Posted September 9, 2005 most of us didn't use the modulator, you sure you had it wired preperly? you can always put an inline fuse on the outgoing power wire to the pump if your worried Quote Link to comment Share on other sites More sharing options...
260ZRED Posted September 10, 2005 Share Posted September 10, 2005 i burned my fuel pump during my turbo swap i had the blue/red (gettin power12 v switched) for 5 secs and turns off. Isn't that what's supposed to happen?? I mean if the ecu doesnt sense the engine is running it turns off the fuel pump in 4-5 seconds. Like evildky said, a fuse is a very good idea if you are worried. Also the factory fuel pumps often die by themselves, it's very very common (rust/crud in the gas tank, wear and tear, etc.) Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted September 11, 2005 Share Posted September 11, 2005 if I put my key in the on position with the motor not running, my pump just runs and runs... Quote Link to comment Share on other sites More sharing options...
