Fuel Pressure Regulator Gas in Cylinders

[shotaurus]

I was taking off from a stop and the car just died , tried to start it and the engine sounded like it was locked , so I checked the fuel pressure regulator and there was gas in the vacuum line , I replaced the regulator and by the way it is discontinued , I found an aftermarket one , anyway I assume I have to take the spark plugs out to get the gas out of the cylinders , anything else I should so? thanks.

The fuel regulator holds vacuum , what else can it be? thanks.

Yeah, do it outside and don't smoke while doing it. Remove the sparkplugs, crank it over a few times with the DIS disconnected. Your cylinder wall might have been "washed down" with gasoline. Squirt a few squirts of clean engine oil in the open holes and replace the plugs. Continue to turn the motor over without starting it. You need to get the coat of oil back on the cylinder walls before you re-start the motor. After about ten seconds of cranking, re-plug the DIS back in and start her up but don't rev it up. Let it idle up to operating temperature and then shut it down and drain the oil and change the filter. Drive it for a few days and change the oil again.

If you had fuel in the vacuum line, the FPR's diaphragm is leaking and it is defective.

Thanks , I will try it , could it also be a stuck fuel injector?

That wouldn't put fuel into the vacuum hose that is attached to the fuel pressure regulator. Only a bad diaphram inside the regulator would do that.

Well it runs but will see if there is any other problems , thanks fo rall the advice.

What does that other vacuum looking deal do? the one that is on I think the return line right by the fuel pressure regulator , it5 has no vacuum line but could that also go bad , if it does go bad what does it do? thanks again.

That other round thing is a pulse dampener. It's on the feed side of the fuel rail and the regulator is on the return end.

So would the "pulse damper" be defective also? would it flood the Engine as well as the Fuel Regualtor being defective? thanks again.

The FPR has been confirmed as defective. Have you replaced it yet?

Yes I have , brand new FPR , I was just wondering for anything else to look at , thanks.
