What engine, in what country?
Each engine has its own EFI even gas and diesel
we can not guess what whats under your hood.

why not log into mitchell DIY and read it your self'
oops it asks same question.
the FPR is DYNAMIC and has 3 tests. not ONE .
the service manual covers all that, if you buy one,

  1. key on pressure
  2. idle
  3. and WOT< wide open throttle (same as #1)
and at full vacuum even less.
our engine is 2.0L and 2.3l j20 AND J23

MY CRUMMY BOOKS ONLY SHOWS. AT IDLE.
31.3-36.9 psi.
but, (physics 101)
IT WILL BE more at wot by about 6pis (at sea level)

and less at full vacuum.
its a 1 bar, FPR.
wot = wide open throttle

this device does 3 things.
regulates
and compensates for altitude
and compensates for induction plenum pressures(vacuum)
at all throttle angles.
make sure the vacuum nipple does not leak fuel or its bad.

SOURCE: ford focus fuel pressure

you are interferring with something you know nothing about,dont you have an annual vehicle inspection to check that vehicle conforms to whats on the paperwork,or are using this just for track .as a vehicle with this sort of modification with no cat on either is illegal to use on the road.the brakes cant cope with extra power the suspension ,the chassis in fact everything is not designed for this if you want a faster car buy a nice jag or a porsche evan consider ferrari or lamborgini

SOURCE: Where is the fuel pressure regulator on a 2003 oldsmobile alero?

There are 2 fuel lines connecting to the fuel injector rail. The larger line is the pressure line and the smaller line is the return line. The smaller line attaches to the fuel pressure regulator. You will notice that the regulator also has a vacuum line attached to it. If you are planning on changing it your self, let me know. There is a specific way to change it for safety reasons.
Let me know.

My 2003 Suzuki Aerio sometimes starts right, sometimes struggles but starts, and occasionally won't start at all. Maybe the starter or ignition switch??

First of all, if the engine turns over, you DON'T need a starter or an ignition switch. Don't fall into the 'let's try replacing this' method of car repair! It is costly and never works.

First replace the cap cap, it is part of the pressurized fuel system and may be the answer to all the issues. $20 from Walmart, or $15 from Napa Auto Parts.

Then connect a code reader and find why that Engine Light comes on. Your vehicle has a computer that records everything that is wrong with it. A cheap code reader gives you the basics, a $5,000 scan tool computer tells you everything, historically and in real time as the vehicle is starting of being driven.

The other thing to check is that the battery is good. Interstate will test for you for free in the parking lot and only takes 2 minutes including the printout. I think AutoZone and Napa also does it.

Idle problem

Sounds like the fuel pressure regulator is shutting the flow of gas causing the higher pressure. The pump is probably ok since it is delivering fuel pressure.

Have 2003 suzuki aerio won't idle after temp light goes out

the engine can not idle right for vast reasons.
wont idle, does that mean
1: stalls.?
2: or wont regulate, hot.
3: or both.
So , no DTCs, no cell lamp glowing , running?
you replaced some very expensive parts, by guessing?
checking fuel pressure costs $20 for the tool.
do you have a $50 scan tool? if yes, you can scan all sensors.
and see if the sensors all look good. do they?
did you buy a used maf ,or new suzuki maf $$$ or the china clone.
most of the clones are no good.
best is , used, and from Cardone.(rebuilt by pros)
the China clones , read wrong, the ECU does not know its wrong
because it is not stuck at 0 or 5v. so assumes its right and is wrong.
with a scan tool you can see the MAF read wrong. do you?
what i do is plot TPS angle, RPM and MAF output and log that.
then at home read the values.

the #1 reason for stalls is leaking EGR. ever clean and service it?

What is the fuel line pressure suppose to be,while running,on a 1998-4.6l-F150-V8?......Im at 30-31 psi....Having Misfires

Normal fuel pressure at idle is 30-40 psi. You should be able to disconnect the vac line to the regulator and see pressure go up.
If you think pressure is low, the fuel filter would be the first suspect.
The pressure regulator could also be faulty.
