New Walbro fuel pump cuting out???

[clone]

just had a Walbro fuel pump installed. the car is sputtering and dieing intermittently
The sending unit is not in good shape,

I isolated the wires from the sending unit and just ran 2 wire straight to the pump.
still not working

Has anyone had the Walbro pump crap out on them?

I ordered a new sending unit and plan to do more tests to see if its the pump or electrical. But I don't know where to start.

f*ck electrical snags suck..
good luck man

are you sure you had a genuine walbro?

[cortexx]

I've had several walbro pumps crap out on me , all genuine walbro pumps . Use a supra pump instead or a nismo maybe ?

[clone]

Ya my first choice was Tomei $$$$$$ hey how much are Nismo's
How did you know it crapped out
I am think of hooking up my multimeter and if It has constant voltage when it craps out. I figure its the pump.

I bought a tomei pump for something like 500$ or something. Not bad when you know it's going to be reliable

Hey <cschepp> thanks agiain. I am shopping for a Tomei right now.
---Domestic sucks----

Did you run new wiring or use the old wires( just wondering because gtr pumps are two staged through ground)

[danwit]

When you ran the wires to the pump did was it after the relay? Ive heard of people having problems with the relays going for a dump. I bypassed mine so the pump runs constant, this will shorten the life of the pump of course, but id rather have that than a shoddy relay causing problems.

read another thread: cut open the harness in the trunk and run the large brown wire(ground) to the strut tower or floor

What do you think?

[cschepp]

I don't know if that's too good of a ground there man. Is it bare metal?

[Bruizer]

I might be selling my tomei if I can find the right upgrade. Tomei are good but there's better options for the price they are.

Hey guys I just put a walbro in my gtr and it was working fine now it's cutting out and bogging down just like the stock pump. if u look at this picture, that little clip that's hanging to the right was a second ground on the stock pump but the walbro didn't have a place to ground it so I grounded it to the pump just like the stock unit could that maybe be the issue?
Also I keep reading to ground a brown wire in the trunk I just cut the thick brown wire and it is a dual wire (wire in a wire) and I grounded that straight to ground but still no luck. Would appreciate any help

[cortexx]

I would consider the installation of a fuel pressure gauge and then watch what the fuel pressure is doing during the bogging.

It may not be the fuel pump at all.

Isn't there a common ground in the trunk the is common to **** out on the gtrs? I have heard something like this before. Hopefully the right person that knows what I'm talkig about can chime in
