I'm just curious, by 17s you're talking almost all the time when you're into boost?

No damage?

A narrow band in my case would have said lean. Testing fuel pressure would show low pressure, replacing fp didn't help, 2nd time taking fuel pump out and I noticed the ripped line, wide band wouldn't of helped. Full rich on a narrow or wideband won't tell you much. Again, they're great tuning devices but they're not the best to diagnosis a "broken" car. That said I'll never live without one.:fawk:

Holy fuckin shit whats with the newb feild day. ok hyper her goes your fuel pump is dieng. Plz get a real one and you will be fine.

My first clue is the car is only slower when you put more demand on it for power ie boost.

My second clue was that your fuel pressure went from 40-60 and back down to 40 while trying to accelerate get a walboro 190 hp and you will be fine to go back to the way things where.

MY 3rd and final clue was that your shit has been fine for 8 yrs nothing runs for 8 yrs and then magically goes out of tune.

Now you can listen to my sage advice or run all over the earth doing what these newbs suggest. If you think im wrong you could pm your symptoms etc to any other regular ie Braineak, olderguy, turbotim and they will say the same thing. GL to ya man.

Yea your lean.......

Check all your vaccume lines, If you have a leak, the afpr will not get the proper boost.

And what is up with the bipes, NOT PULLING TIMING! This could be a issue as well. What is your base timing set at?

You need to set the proper settings on the bipes and set the base timming to 14*.

Check all vaccume lines. And double check boost pressure. You will be lean anthing after 5psi. Or atleast I was!

BUT YOU SOUND LEAN FOR SURE.

17's in boost is basically so lean that the car would just fall on its face, not make any power. It probably bogs so hard that it cant even really detonate

Ok guys i ordered a Walbro 190 and it will be in tuesday. So today i was doing some tests. When i jumper the gnd and ten and turn the key to on there is no fuel pressure on the gauge? Does that mean the fuel pump is gone? but when i start up the car it's at 40 and it stays there even when i'm driving so i try to stay out of boost. And when i shut my car off after driving the fuel pressure gauge says at 40 even after 5 mins so injectors are fine.

is it a mechanical fuel gauge? If its mechanical it should stay the same psi after you shut the car off for days. It should not go down to 0 unless you have a fuel leak somewhere or ur fuel pump is shot and not holding pressure after you shut it off.

Do you have to crank on it for a long time for it to start?

Do a little search, but I am pretty sure that you want to jump Fuel and Ground, not Ten and Ground. The latter is for setting timing.

Like others said, at idle squeeze the fuel return line with pliers, and watch to see if the fuel pressure rises up to around 100. Your engine will start to bog down from the extra fuel when you do this.

happy tuning.

oops yea i jumpered the F/P and GND and the fuel pressure gauge says 40psi

Did you check the vaccum lines for leaks to the fpr??????????????????

yep checked it all but i'll double check again. Is there a way to test vaccum leak or do i just have to listen and feel for it?

u got a vac or boost/vac guage?

yep vaccum is always at 20 at idle like normal

does the car idle high or surge

It idles normal. No jumping.

Have you ever replaced the fuel filter? ive seen alot of cars where the owner has never done so. Im just guessing here. I try and change mine at least annually.

Hmm the fuel filter is still stock. I'll get that changed. It's got 176,xxx miles on it.

Take it to a local auto shop with a smoke machine. It fills your intake with pressure and smoke it will show you if anything is leaking. Its relatively simple to do as well so it wont cost much.

WTF man why cant you be more like him and give good advice
On the note of vac leaks, you can use a flamable spray liquid ie wd40 etc, to diagnose leaks as well. But with your idle being at 20 inches etc i think you are fine in that respect.
