recently replaced the clogged fuel pump strainer . and now its not running properly .
i have a nasty sputter from 5500-8000. also when i come to a stop my car dies out .
ive looked over everything i can think of . fuel filters are replaced . fuel pump is pumping ,
could it be my fuel pressure regulator ?
its on my 88 ef hatch with a obd0 b18a1.

 

Could be the regulator. What's the fuel pressure?

 

replaced the regulator .
my fuel pressure is sitting at 40 psi at idle .

 

bump, my stock ef does this too

 

Try cleaning out the screens on the tops of the injectors? Or even the fuel filter?

Maybe you stirred up some **** when you changed the sock.

 

Sounds like a clogged fuel filter to me. Like said above you might have stirred up a lot of stuff in the tank when you changed the strainer. I would also check the injector screens and the injectors themselves. 40 psi with vacuum applied seems a little high to me, should be more around 35. This might be a sign of clogged fuel injectors.

 

all filters and screens are cleaned .
also a new fuel problem , im driving normal , and hit the brakes and my car dies. i have a full tank of fuel . and all vaccum lines are clean and clear .

 

Did you "clean" the fuel filter, or replace it?

It's something that get's replaced, the one on the firewall, not cleaned.

 

all were replaced three days ago , not cleaned sorry for the mix up.
also found the problem .. went to change my timing belt , timing belt is still good .
the problem was a broken rocker arm.
