I tried after you told me to pull the O2 , the battery is getting weak, cranking and not starting,
as i said before came home from work, started up fine, ran for 10-12 mins then started to act as it wasn't getting fuel,so we go back to is it getting fuel, did we do right? my neighbor from the get go said it was fuel pump, but i respect your guys opinion,this is had to figure out , i wanted to pull O2
but rained and dinner and getting dark, ALSO when car was running on saturday after stalli backed in driveway,so nose of car pointing down slight slope of my driveway with gas tank at top of drive is the car getting some fuel from downslope during daytime then i come home, run for 10 mins then stalls

Today came home,swapped out fuel pump relay with other fuse,started ran for about 2 mins then stalled, started again run muffled for 30 secs.stalled,
so I pulled off O2 sensor like you said ran for 1-2 mins then started fluttering had to pull throttle to keep it running,very loud while running
So I have put on new plugs,pulled O2 sensor, checked F.Pump relay, i need to replace some rubber boots to air lines this weekend,i''ve also noticed NO fuel coming out of fuel lines-(disconnected) is that NORMAL????? No corrosion on coils, I will check them this weekend as demostrated!

Do you guys have any other checks or solutions? Thanks for your input and help since this hasn't worked should i replace fuel pump?

When was the fuel filter last replaced? Sounds like you are getting starved for fuel.

my car had the same symptoms, i changed the fuel pump and now it runs great again, the fuel pump filter was so gummed up i'm surprised it was able to suck any juice at all, which is probably what helped kill it, probably wouldn't hurt to look at, it'* not too hard a job to drop the tank just be careful separating the lines if you do it...good luck!

For what it'* worth.....my 94 bonny SE had similiar symptoms. Before you start the car turn the ignition key to on and listen for the slight humming sound of the fuel pump. If you don't hear it...it may be a fuel pump issue. You can check the fuel pressure with a gauge that hooks into the valve on the fuel rail. Don't start buying/replacing items on a whim...it will get very expensive. Been there done that!!! Use deductive reasoning to rule out what works what doesn't work. Start at is the car getting fuel ? (fuel pump, fuel filter) then is the car getting spark ? and so on. Mine ended up being an ignition control module and a knock sensor. Good luck!!
