It's easier to replace a regulator-either from the junkyard or purchase a new one from the local auto parts store, etc.
It all depends on what kind of car and engine...most are fairly easy to do.
Look it up on Autozone.com; log on with an ID and password and get a repair guide for many vehicles ..and get one/or manual from Amazon for many cars or trucks, vehicles.

99 tarurus stop getting fuel.


Could be a fuel pressure regulator or lost signal from crank sensor that gives inaccurate data.
The crank sensor is responsible for sending data to increase fuel pressure as a function of increased RPM. If the RPM reads low, then fuel pressure will be low.
Check fuel pressure.
Thinking that air pressure is affecting pressure regulator and compensating for a weak regulator diaphragm.
Would be interested in final fix of your problem.

Check/replace the fuel pressure regulator. Pull all spark plugs out so the excess fuel can evaporate. The pressure regulator should fix this issue.

1990 buick century limited/ v-6 engine has fuel in the oil. need a fix.


could be a bad fuel pressure regulator. if they do fail, then it may result in low pressure. Mostly, the diaphragm in the fuel pressure regulator develops a leakage and the fuel enters the vacuum hose. This may lead to various kinds of troubles in the engine. Signs of a Bad Fuel Pressure Regulator
  • The vehicle engine runs rough and often stumbles and sputters.
  • The engine will not start after ignition. Usually, this problem is encountered in the morning when you start your vehicle. Many times, the engine starts, but stalls shortly after starting.
  • The fuel pump in the vehicle becomes noisy at times.
  • A bad fuel pressure regulator can also result in fouled spark plugs.
  • Last but not the least, the fuel mileage of the engine decreases noticeably. if above signs appear, replace fuel regulator. Check the oil dipstick and see if you smell fuel on it. If you do, it could be a symptom of a bad fuel regulator. The regulator has allowed gasoline to leak into the oil system.

Could cloaged fuel injectors cause fuel to leak out of throttle body on a 97 buick lesabre ?

Hi Steven Phillips:
It's possible but not very likely unless there has been a recent removal of the injectors and new O rings were not installed.
I suggest that you take the vehicle to the closest AutoZone and have them perform a fuel pressure test and a full diagnostic scan. Both are free of charge.
It's possible that you have leaking fuel line or fuel pressure regulator. The pressure test will enable you to evaluate both possibilities. Incidentally, replacing O rings, fuel lines and pressure regulators are fixes you can do yourself.
Feel free to follow up with me should you so desire.
All the best,
Ben

Hi, my 2001 Pontiac Grand am SE 4 cylinder 2.4 engine has been starting very "rough" as it runs however it eventually fixes itself. Also my coolant has been "disapearing" i keep having to refill the...


Probably needs cylinder head and gasket, for that rice. Cylinder head gasket is around $1700-1800.00.
Fuel pressure regulator is not too difficult, you have to disconnect fuel line where it goes into fuel rail. and remove regulator, then install new regulator and put fuel line back in. You will loose some fuel, so loosen fuel line slowly, and put a rag around it to keep if from spraying out too badly.
Hope this helps.

Have gas in engine oil


HI, this unfortunate leakage of gas into your oil is being caused be a faulty fuel pressure regulator. there is a diaphragm in the fuel pressure regulator assembly that may have ruptured, in return, sending small amounts of fuel into the intake, via the vacuum line that connects the regulator to the intake.

simply replacing the fuel pressure regulator will fix this issue.

Please rate and god bless:)

Open fuel regulator control


There are 2 fuel pressure regulators on your fuel rail. They are being held in by a clip. Just remove the clip and it will pop out. Don't forget about the seal.
