fuel pressure regulator?

To find the fuel pressure regulator you will have to take the Plenum off...... it is located in the center of the picture....

If I may ask were do you live, I ask because you mentioned Murrays....

How much should it cost to replace a fuel regulator on a 2001 Chevy Blazer 4wd?

Plus cost of part, shop supplies and tax, of course.

How much should it cost to replace a fuel regulator on a 2001 Chevy Blazer 4wd?[/quote:ec61f09cda]

On my 1997 I was quoted $453

Thanks!

Got a 2001 Chevy Blazer, 4.3 Vortec 6cyl. csfi Where exactly is the fuel pressure regulator located? Cant seem to find visually Dont see exposed fuel rail Do i have to remove the intake manifold? Can take a picture of engine if that would help of course its snowing now!!!

I have a 4.3 6cyl. 2000 chevy blazer with the vortec. The regulator I hate to say is under the manifold with the spider injector. Im having the same problem with mine. The engine cranks but wont start. The pump is working and the filter was changed. Good luck Ive learned my lesson with this Chevy. Here are diagrams to help you see what I am talking about. Check out the diagrams (Below)

This was the problem with my car, runs great now got the new spider from Amazon for $210.00 Love this site.

where is the fuel pressure regulator on a 2000 blazer 4wd v6.

inside the intake manifold

Under the upper section of the intake manifold. On the rear of the injector assembly. If it was mounted on the front you could change it without opening the intake.

I tooked my car to the mechanic two weeks ago. The car had its tune up and a week later, they replaced the gas regulator, because had a gas leak problem. After that the Engine Soon Service light came on. The codes problems are P0171 and P0174, which means the engine is running lean. The mechanic check the vacuum lines, clean the inyectos and clean the oxygen sensor. But the light is still on. Could you help?

most likely when he replaced the regulator(which he had to remove the intake plenom) he damaged the intake manifold gasket and he should take care of the repair if he is reputable. let me know how you make out

My Blazer is hard to start (can smell fuel when trying to start) and doesn't have much pickup when accelerating. I have been told it need to have the fuel pressure regulator replaced and this is very expensive. Is this correct and how do I know what it should cost?

may want to start with replacing the fuel filter first. clogged fuel filter could cause these symptoms. if filter is clean then a bad fuel pressure regulator could definitely cause these same symptoms. estimate is below for having your vehicle's fuel regulator replaced.

ive had this car for about 2 mths when i go to start it ,its hard to i spray some starter fluid in it and it fires up and is fine , latly it was starting to bogg out then now it wont start , fuel pump primes , pressure goes up to @60 then immedetly drops , i think it is the fuel pressure regulater how do i manually check it? , do you think its the spider injectors, i v already took it off and dont know how to do it manully feel free to call me at 321 322 8238 i need help

I dont think its the injectors, at least not yet. sounds like your on the right track with the pressure regulator. I would check the fuel filter first before going to the regulator. if the filter has been changed and still acting up. while the car is running. pull the vacuum hose off of the pressure regulator, there should be no fuel leaking out. if so , the diaphram is at fault, replace it

thx for the response, it has a new fuel filter , regulater is good, new one in there , i put it back 2 gether and im getting iol, and fuel coming out the tail pipe, and a sluggish fell to the car, i think that is the injectors, i think i put them in wrong or ###### them up when i tried to clean them what do you think? thx

Bob and Ken,

Thanks - used your service to debug my "rough start - gas smell" problem to a leaky fuel pressure regulator in my CPI. I replaced the regulator and the car ran perfect - problem solved! But hold on - after just one hour of driving I'm back to the exact same problem all over again. Looks like the root cause is something else breaking the pressure regulator. Could this be excessive fuel pressure from the pump? Is there some part of the CPI that could cause this?

thanks in advance for you help

Does your 95 have the aluminum upper plenum on the intake?If so, they had some other problems with the fuel lines inside the intake getting leaks, this could be why the problem came right back.You can remove th eupper intake and turn the key to "on" position to look for fuel leaks.You will probably have to clear the PCM afterward

need to find its location.

4.3L V6

If its the CPI spider system its under the upper plenum on the passenger side-TBI behind the injector

Looking at the pic the pressure regulator its on the L/side and R/side Nut kit

how do i replace fuel pressure on 4.3 vortech engine?

Properly relieve the fuel system pressure and disconnect the negative battery cable.
Remove the fuel return pipe from the regulator and discard the old O-ring.
Disconnect the vacuum hose from the regulator.
Remove the fuel return pipe clamp.
Remove the pressure regulator attaching screw, then remove the regulator and discard the O-ring.


To install:

If the old pressure regulator is being installed, check the filter screen (if equipped) for contamination and replace, if necessary.
Lubricate the new O-rings with clean engine oil, then install them on the pressure regulator and fuel pipe.
Install the pressure regulator onto the manifold.
Make sure the regulator attaching screw threads are covered with Loctite 262 or an equivalent threadlocking compound, then install and tighten the screws to 31 inch lbs. (3.5 Nm).
Connect the vacuum hose to the regulator.
Make sure the new O-ring is in position, then connect the fuel return pipe to the pressure regulator and tighten to 22 ft. lbs. (30 Nm).
Install the fuel return pipe clamp and attaching nut to the lower intake manifold assembly.
Connect the negative battery cable, then pressurize the fuel system by cycling the ignition (without attempting to start the engine) and check for leaks.

Hello, this is my first post in this forum and I hope that someone can help with my problem. I feel I'm a capable backyard mechanic so asking the following question is sort of like being lost and being forced to ask for directions...a bit embarrassing! Anyway, my son just purchased a 1993 Chevy S10 Blazer, 4.3 engine, 4WD, automatic with 125,000 miles. It runs very rough and has a strong smell of gas. I changed all plugs, wires, distributor cap and rotor. Still runs rough. Upon removing the plugs I noticed that all three plugs on the drivers side of the engine were black with soot. The three on the opposite side looked normal, if not overly white. I realize I have a fuel injection problem, but what in the injection system would effect only the one side of the engine? Could a Fuel Pressure Regulator be the culprit and is this something I could replace? Thanks for any info you can provide. Bill

93 CPi's had other problems beside the regulators.The fuel lines in the intake have been known to pinhole, causing raw fuel to be sprayed into the intake plenum. The lines are on the d/s , so I would suspect that could be the problem. Remove upper plenum, and turn key on, but DO NOT CRANK, if any fuel leaks they will be readily visible

What is the procedure for installing a kit in the fuel pressure regulator of an 1989 5.7 K5 Blazer TBI ?

Make sure no pressure on system, Remove top torque screws, the autostore sells a fitting to remove those. You should be able to remove only the top part. Picture below.

And then what ? I understand the regulater is under spring pressure. How to disassemble, reassemble, and what are the alignment issues, and torque values for the fasteners ?

You shouldn't have any problems, just put it back together the way it came off. I don't use a torque wrench on screws that small, maybe I should? Torque specs are below.

Thanks very much !

You bet.

Where is the fuel pressure regulator located on my 1986 chevy blazer.

It looks like this below and its located on the fuel rail
