Ok, good start.

To those with stock fuel system,and a Fuel PRess Gauge.
What is your fuel pressure at idle? What is your fuel pressure when you 'turn on' the ignition,and what is your fuel pressure at redline?Where is you gauge tapped?
4 easy Questions. Wonder who willl answer first?

add 10 psi to those numbers I sent to you... now that Ray has broken the sacred oath of non-helpful replies, he'll need to find a new brotherhood. I heard Bodizipha is looking for a new herd....

Would a bad pump cause low pressure at turn on? Or Idle?
Nivo, what pump are you guys using?

stock pump and clogged filter, with that fuel pressure afr's were 12.9:1 from 5k rpms to 6200rpms.
everything was better after a filter change.

then we got our return set up with walbro 255lph pump and non regulated filter.

Whoa charlie.....
Filter?
I thought the filter/reg was one unit?
I used to see 54PSi at idle, tapped at the end of rail. Now, I see 44 :stab:
The Reg has been changed, but I thought the filter was in there.....
is the filter actually the thingy at the bottom of the pump?
I hate to drop this damn tank.

well there are 2 filters...one at the pick up of the pump and the actual regulator.
we had changed both. but then the new walbro 255lph came with a new one.

54 at idle? hmm seems low. we saw that at/before redline...

:EDIT:
let me mention that we changed the stuff 14k miles ago. I would suggest even changing the regulator/filter after 20k if you are racing the car. especially if you drive to some place where you have no choice but to gas up at a station where the guy behind the counter has 3 teeth, you have to manually pump the gas.

so you are saying you are running lean?

I hear ya on the 3 teeth special. I dont think I am running lean, because the pressure at idle is at what I USED to see at redline. I guess ill have to change the pump and pickup filter this weekend....

We carry a fuel filter with us, just in case.

Regular people don't drop the tank to even change the entire pump assembly, but we expect you to do it Cali, because nothing should ever be easy for you.

It's rare for a pump to reduce output, they usually just whine and then die (it's too bad more whiners don't take that route, we'll maybe jsut seriously nauseous) but dirty filters are very common.

On first gen Neons with low pressure problems, and new pumps and filters, the problem is usally found in a bad ground, or damaged wire, for the pump. The pump likes it's voltage... Damaged wires don't always look bad on the outside, like a newbie, they can hide the evilicity deep inside, waiting for you to be vunerable.... then, "Whiiineee, eh..." dead... hey, there's those voice shouting at me again...I'm easily encouraged...
