Yo, i need some info and help possibly. Well i put in a use tt fuel pump in my car to see if me gettin fuel cut will stop, well it stopped for a lil and then it started back up. Well my question would be what will cause me to get fuel cut. Would it have anything to do with o2 sensors...my ecu or even the fuel pressure regulator. so if you guys could point me in a right direction or even give me possiblities on what it could be and how to fix it...would really be helpful thanks

 

is it definitely could be your fpr. It could also be your fuel dampener or a dirty fuel filter. I'd recommend replacing all of the above. Also, run your car for codes and see if anything comes up.

 

It's probably not your ECU or O2 sensors.

I'm willing to bet it's the FRP or dampener (or both). Search for different permutations of "fuel system diagnostic" posted by me - I've explained it thoroughly on at least three different occasions and I can almost guarantee that the diagnostics I detail will tell you where the problem lies.

 

make sure your fuel pump relay is plugged in good.
