3ryce Posted March 22, 2013 Share Posted March 22, 2013 Ok so ive got a 1973 240z and its got the electrical fuel pump in the back that I guess primez the system to allowe the mechanical one to take over. Well im not getting power to the pump. I here clicks over in the relays on the passenger side. The inline fuse is good and everything seema plugged in. Someone had told me about a relay coil or something that could be bad. Im trying to figure out where that is. The haynes manual does not say and I cant get an answer from the other person. So if someone could point me in the right direction that would be awesome! Thanks. And ill keep looking around the site in the mean time.

3ryce Posted March 22, 2013 Author Share Posted March 22, 2013 And is there a way to jump the wires to test to see if the coil or relays are the cause. I do not have a volt meter with me and its 20 min away. Quote Link to comment Share on other sites More sharing options...
beermanpete Posted March 22, 2013 Share Posted March 22, 2013 The fuel pump in the 73 does not get power through a relay. Look for an in-line fuse holder near the fuse box with green wires. The fuse should be 20 amps. The car will run without the electric fuel pump if the mechanical pump is working. Quote Link to comment Share on other sites More sharing options...
3ryce Posted March 23, 2013 Author Share Posted March 23, 2013 so i jumped the wires that this was plugged into and turned the key and the fuel pump worked. so this relay is bad and not working. heres a picture. and idk what to call it cause i know these cars dont have a fuel relay persay but this is defently a relay and controls the fuel.
