On my way to work and my fuel keeps cutting off when I give the car gas and my af gauge reads nothing, it will idle between 13 and 15 on the af gauge. Ia my fuel pump bad? Im also getting a lean code

 

or clogged?

 

Well its been doin this for the past month if I went below a quarter of a tank, now its worse and did it with half a tank left

 

change filter

 

It's a filter, not the pump. I've never had a pump that would cut in and out, it's either working or it's not. I HAVE had a clogged filter cause the car to cut in and out.

 

Well damn that sucks cause its a new filter I got with my return fuel setup last month, would the filter cause me to lose pressure? Because after an hour of the car sittin the pressure is back at 0

 

You sure your wiring is kosher? I've had bad fuel pumps before, and they don't "act up" long term. If it's going bad, you've got maybe enough time to get off the freeway so you don't get creamed.

 

what fuel are you using? maybe your maf sensor is gone and your code is disabled?

 

Im running e85, I called ottp and they said my fuel pump is prob bad which is the reason y im losing fuel pressure.

 

is it possible your e85 mixture at the pump changed to a different blend?

edit: if you lost fuel pressure idk then ^

 

Usually a pump failure is a no start issue and it just wont work. Is it loud/noisy?

 

Zactly. First two times I had a fuel pump go it was working fine then not working at all. When it went right after I got the Cobalt, it started, sputtered for 2 seconds, then gone. A bad fuel pump sure as hell won't last a month.

Just out of curiosity, what injectors are you using?

 

fuel pumps will start producing less pressure as they go bad then quit working what causes them to star producing less pressure is the brushes are dragging on the com which slows the pump down which produces less and less pressure till they just stop working

 

This is more like my situation. But im curious because would the pump being bad cause my car to lose fuel pressure with it being turned off?

 

it will loose pressure over time and it not running thats normal

 

Ok ottp told me when the car is off its suppose to keep its pressure up on the regulator. Im curious though, the instructions on the return fuel install said to remove the metal mechanism on the stock regulator. Did it just mean the little metal ball or the whole metal piece?

 

listen its supposed to keep the sysem pressurized when its off for a certain amount of time (usualy 20 min or so) it will bleed off
