What are the symptoms of a bad fuel pressure regulator ?
Q. My 90 olds ciera isn't running right. It only runs when you throttle it up but doesn't run at idle. Also when you give it gas, it runs choppy and the SES light comes on, I cant get the codes because there is something wrong with the diag wires. The car DOES run but very choppy at idle when I unhooked the vacuum to the fuel pressure regulator, it does have vacuum too. So what is going on with my car? Fuel pressure is okay, it is at 45 PSI.

A. if your showing to have 45 pounds of pressure you don't have a problem with a fuel filter you probably need a new regulator on it those will cause one to run bad like that,gm products was famous for having those go out ,good luck.

Location of the Fuel Pressure Regulator on a 1988 Dodge Dakota Truck with a 3.9 L Engine?
Q. Hi. I need to know where the fuel pressure regulator is located on a 1988 Dodge Dakota Sport with a 3.9 L V-6 Engine that has an automatic transmission. 2 wheel drive. I believe it is near the carburetor but I am not sure. Any help or suggestions will be appreciated. Thanks for the help. Byron W.

A. Is this a carburetor or TBI (throttle body injection)? They are often confused. The pressure regulator is most likely internal to the throttle body. Are you sure that your problem stems from the fuel pressure regulator?

A. On most vehicles it is on the fuel rail so the above posters are sort-of correct. But you have a Dodge which means the Regulator is mounted on the Fuel Pump Module inside the tank. The whole thing gets replaced as a unit.

Replacing a Fuel pressure regulator on a 98 Chevy Blazer?

How to change a fuel pressure regulator.?
Q. In a 95 blazer, where is the fuel pressure regulator and how do I change it and is there anything I need to know about changing it?
Asked by Opie - Tue Sep 15 23:55:39 2009 - - 2 Answers - 0 Comments
A. If I am not mistaken, the fuel pressure is actually regulated by the fuel pump located in the fuel tank, along with a bypass return line located on the back of the TBI. Best bet is to look in a Chilton's or Haynes repair manual, found at ur local parts store...if your pressure is low, try blowing compressed air backward through the fuel line. pretty sure it's not too high, unless the pump came from somewhere else than the factory. you can buy your own regulator if it is too high, but make sure it is designed for injected applications and maintains specs that are in the manuals.

Does changing the fuel pressure regulator increase gas mileage? ?
Q. I heard that by changing the fuel pressure regulator, then gas mileage might increase. Only of course if the current regulator is malfunctioning. Would anyone have any extra info for this? OR, changing the O2 sensor?
Asked by jessetruitt3 - Thu Nov 20 12:19:41 2008 - - 4 Answers - 0 Comments
A. Changing the O2 sensor will make a difference if its been about 40,000 miles or more since it was last replaced, they get old after so long and send bad values to the computer which affects fuel economy. As for the regulator, yes, if its malfunctioning it can bring your economy down, so changing it could help. However, if it is letting slightly (and i mean slightly, maybe 3-5 psi) more pressure through than normal it will cause the fuel to create a better mist from the injectors, causing the fuel to burn more efficiently since the gasoline vapor is way more flammable than the liquid and you could end up with maybe one more mile per gallon.
