Fouling out plugs

You know, I gotta jump in here. All you have accomplished now is to ruin your fuel pressure regulator. There is no reason that should ever need adjusting and you don't know how to set it up properly anyway. Low fuel pressure would mean something else is causing it, not maladjusted regulator. When you finally find the real problem, you'll likely have to replace the regulator now too.

Sorta figured low pressure might be from something else. But. They say it's "TOO HIGH". Mr. Chilton says how too adjust it to 14.5 PSI.

I figure too much pressure, would also mean TOO MUCH FUEL THRU THE INJECTORS, in a "given period of time"

Maybe someone s. Crewed with the regulator in the beginning, to get too much fuel. TOO RICH, That was the subject of the post.I do understand flow.I am a plumber!

All yours now!

No more CJ MEDEVAC tampering on this one!

I will continue to watch this post. To see the "Big Thank You, and sloppy kiss", at the end, after you have given your 110% of effort to fix the issue, I look forward to hearing it run!

I'm not taking over this question. It's yours now. I just have one question. Did anyone ever even bother to use a fuel pressure gauge before messing with the fuel pressure regulator. You don't even have to respond because I already know the answer.

Post your email I will send a PDF with all electrical testing info, fuel pressure should be 14.5 psi.
FUEL PRESSURE REGULATOR
WARNING: Always relieve residual fuel pressure in fuel delivery system
before opening system. To prevent chance of personal
injury, cover fittings with shop towel while disconnecting
fittings.
Replacement fuel pressure regulator must be adjusted to establish correct
pressure. Remove air filter elbow and hose. Connect tachometer leads to
diagnostic connector D1, attaching negative lead to terminal D1-3 and positive
lead to terminal D1-1. See Fig. 4. Remove screw plug and install fuel pressure
test fitting.
1.
NOTE: Fuel pressure test fitting is not included with throttle
body. Fitting (8983 501 572) must be obtained
separately.
Connect fuel pressure gauge to test fitting. Start engine and increase speed to
approximately 2000 RPM. Turn Torx head screw at bottom of regulator to set
correct pressure. Turning screw inward increases pressure and turning screw
outward decreases pressure. See Fig. 3.
2.
All models require fuel pressure of 14.5 psi (1.0 kg/cm2 ). Install lead sealing ball
to cover regulator adjustment screw after adjusting fuel pressure. Turn ignition
off. Remove measuring equipment and test fitting. Install original plug screw and
air filter assembly.

BTW codes can be read by anyone who has the ignition key. Turn key from off to on three times, then leave on on fourth turn, codes will flash the check engine light, count the flashes. 55 will be the last code, it means end of codes! Read flashes first digit, is short flashes, the second digit displays after a short pause, and flash longer than the first. More than one code, the pause will be longer between codes. Codes will display three times.

You may have a problem trying to get flash codes from that vehicle.

Still worth a shot?
