Hi guys, just acquired my new baby. A 1976 280Z..problem is we cannot get it to start, almost seems like the fuel pump is not getting power, now we tried another fuel pump directly connected to the battery and that one still did not show signs of getting power...any ideas? The gas tank is empty but shouldnt we still hear something from the fuel pump?

Any help is much appreciated, i sit in front of a computer all day for work so i will be able to respond quickly to any replies to this post..


Thanks and its nice to be back in a Z.

If you connected the fuel pump directly to the battery and nothing happened it sounds like either the battery is dead or the pump is shot.

fdc_guy

Yeah, that is what im thinking.....should be an easy replacement?

fdc_guy

So if the gas tank is empty would the fuel pump still make a sound or does it have some pressure switch to activate the pump?

best way at this point is to jack the rear up and slide under.

use a 12mm socket to undo the mount bolts.
use a phillips and a regular screw driver to undo the hose clamps and the 2 wire connectors.

take out the pump and then use a direact waire from the battery to see if that works. It should still come on even if there is no fluid going thourgh it.

If the pump is a no go you can get a new one or if you have any junk yards around you can pull one from a z or zx. make sure its fuel injected and non turbo.

Cool, yeah we will get to working on it, Nismopick and myself are the ones working on it...we tried that using another fuel pump from his other 280zx and it did not work either...we will try more tonight, i really want to hear the performance exhaust it has on it..

get a clip and share it with us... and you got nismo pick helpin you in person.. sounds like you wont need much of our help... and yeah if you do direct power and nothing happens either the pump is dead... the battery is dead or you hooked it up backwards. lol... also if you get a working one and put it in and it still doesnt work check the fuses and your afm.. if it doesnt make good contact on teh slide the pump will not run.

skittle

wow you got nismo as your private instructor??? how did you get such a lucky break?

fdc_guy

Haha, i don't know how i got to be soo lucky, we took some before pictures last night, hoping to get them posted up soon.

Nismo and i live really close to each other, like a few blocks...makes it nice when working on your only mode of transportation..lol

snwbrderphat540

nismo doesnt no s30... only s130 lol...

NismoPick

Yo momma don't know S30's! Oh snap! Yeah, we worked on it for a couple hours last night. I have pics at home that I will upload tonight. We'll prolly just yank the fuel pump & see what's going on. The battery is good (even had a charger on it). It's been sitting a while, so the fuel lines may just need to be primed.

snwbrderphat540

my momma doesnt know s30's.... thats why i have my dad.. now i just need to get him to start smokin pot or soemthing so he can mellow out... stresful to work with that guy sometimes...

fdc_guy

So what is involved in priming? Oh and i can get a new ignition switch for 25bucks at autozone, think that is why it wont cut off the power...

NismoPick

Just funnel in some gas to the lines. Did you get a hold of the previous owner yet? Don't buy anything until you get a hold of him.

fdc_guy

He is stumped, he did not know about the fuse thing and says it worked fine when he parked it....so i don't know. He did not have anything usefull to throw into the brain storming i have been doing all day.

NismoPick

Alright... next step: disconnect fuel lines @ pump and see what's goin on.

fdc_guy

Sweet, sounds like fun to me....lol...man im bored at work.

Here is my inspirational picture....

i have that car posted all in my room. the engine everything.. i found that shizzle a while back, i used to love it, but the more i looked at it, the stranger looking it got. still ****in sweet though.

NismoPick

So here's some pics of FDC's 280z. Tonight we got it to kick over & run with starting fluid, but the fuel pump won't kick on. I took off the feed line from the tank to pump... not much to see, tho we put in 5 gallons, and when I took off the feed line to the pump, it was just a steady drip. You'd think it'd be streaming out...







Someone wired in a fuse below the steering column... yellow to red wire???

snwbrderphat540

who did that wlding? its rather... thik. lol. a lil sloppy looking. looks like itl do the job though.. and you gots a project on your hands alright. ****... solve the fuel pump issue though and you got a running car.. thats at least half the battle

NismoPick

yeah... welding thin sheet metal isn't the easiest. They invented the grinder for a reason.

skittle

Wow Now That Is A Project Z... Not The Worst Though.

snwbrderphat540

ooo defensive are we, im guessin this is your work then. hehe... i knwo thats why they inventid the grinder, but your gonna wear down an entire wheel on that slag hehehe

fdc_guy

I think he did an awesome considering what there is to work with there...lol...lots of difficult welds are soon to follow...and yes it is a project...but a very fun one so far. Getting a new fuel pump on saturday and having another crack at her...sounds sweet when we got it running though, that 2.5" pipe from the head back and Magnaflow muffler make it purr like a tiger.


EDIT** Went to Autozone to look at the fuel pumps they have and the one they have showing for my car doesnt look at all like the one thats currently on it, the output end pump to motor is a big screw it looks like, any idea if that will work somehow or if anyone can find me a link to where they have the stock fuel pumps for sale that would be great.

fdc_guy

Ok i called Autozone and they said that the fuel pump they have has an adapter to a line connection, so that means it will indeed work, so i will pick the part up either tomorrow or saturday.
