So I opened up my afm on my 5/77 280z because my fuel pump (I thought) is running when I put the key to the "on" position thinking I was going to have to adjust the arm that breaks the contact point for the fuel pump. I know the pump is usually only powered in the "start" position. To my amazement the contacts were not making contact! So I made them make contact and I heard something else come on. I can't tell if it's the fuel pump, something else is running at the same time. I looked around in the car to see if any other accessory's were running but couldn't see anything. Now for the weird thing, my fuel pressure gauge builds pressure with the key in the "on" position! I…

Hey Guys, When I got my 78 280, as is common the battery was left in and rotted everything below including the fuel lines. I got a new set of steel lines but can seem to figure out how the run from the turn up to engine compartment to the front get secured to the frame. Anyone have a pic?

I have a 77 280Z and am trouble shooting the cold start system. I have been reading post's regarding cold start issues and think I have stumbled on something here. Correct me if I'm wrong but isn't the fuel pump supposed to only come on in the "start" position? If I turn my key to the "on" position my fuel pump runs as well as the start position. And if this is the case then I need to spend time looking at my AFM correct? I know what tests to run from looking at my FSM I just need some reassurance that I'm heading in the right direction. Thanks for your help. Bob

is there anything wrong with hooking direct power up to my fuel pump and running it off a toggle switch? basically i toggle it on when i start the car, and turn it off when i turn the car off. I plan to also hook up a light to it to signal that it's on so I never forget. this fix is only so I can drive to get parts while I figure out my electrical issue.

I am new to the forum and have read tons of great information. But before I start checking everything I thought I would run my problem by a few of you folks first. My 1977 280z runs strong and accelerates as it should, however when I try to accelerate quickly the car sometimes slightly back fires and always stumbles then as the rpm's climb its smooth. If i give it gas say 1200 to 1500 rpm's and ride the clutch out....no back fire and very little stumble. Anyone experience this before?

Hello I am just trying to finally catch-up on my 76 280z and trying to find that infamous fuel-afm problem, in the process I checked the fuel pump , do you think the bending in the fuel line (picture) would affect the flow in the whole fuel process?

I'm trying to put the fram filter between the fuel tank and the pump, however the hose that goes to the pump it is not a 3/8 as everybody is saying it seems to be a 1/2 , attached is a picture of the fuel tank nipple, I do not know if the owner before me tried to "reinvent" the way the fuel flow goes ,due to the fact that he replace the OEM fuel pump and removed the damper ,any thoughts?

The 77 smells like it is running rich and the spark plugs tell me the same. I get a backfire and stumble pulling away from a stop under partial load at low revs. That being said I seem to be getting the same problems others have had I found searching similar posts about EFI problems; and all those seem to indicate air bypassing the AFM or the coolant temp sensor; and others indicate a lean condition with that. My boot seems to be in good shape. What kind of tests can I run on that sensor to check that? Any other suggestions? I want my pile running as good as this pile will run for my trip to Fredericksburg next month. After this trip I am going to pull my Turbo m…
