so i drive home from work park the car get ready to go out turn the key on and no prime sound. so i check the fuse it's ok what else turns the pump on? no pressure and car wont start. any ideas?

 

I have heard of more than one Walbro that has died. When I had my tripple pump hangar, I was only using 2 Walbros, but I put a 3rd one in as a spare. I also put quick disconnects on all of the positive leads so that I could quickly change over should one fail.

 

well its not the pump, there is no power going to any of the wires that attaches to the pump. i tested and swapped out the fuse under the hood so thats good. where else between the fuse and the pump do the wires go? is there another inline fuse? is there a specific relay? so people add in a relay somewhere sometimes for safety that i may not know of that the previous owner installed? please help this sucks.

 

I use an individual relay on each fuel pump. Since you have changed out the fuses and there still is no power to the pump, you are right, it's probably is a relay.

I have a G35, and my relays are underneath the rear seat. But in a Z, I don't know where the previous owner would have located it, but it should be relatively close to the pump... Unless somebody else has a suggestion, it might be time to try to contact the previous owner.
