How do you check the injector pressure regulator on a 2000 silverado 5.3 liter?
Rlrick
If you look at it you will see a vacuum line hooked to it, while the engine is running unplug it and the engine sound should change. If it don't then the regulator is bad.
You can also hook up a fuel pressure gauge to the fuel line and read what the pressure is while engine is idleing and then unplug the regulator and the fuel pressure should go up a few LBS. If not replace regulator.

What would cause fuel pressure drop overnight on 2003 Chevy s10 4.3L MFI?
Could be a faulty check valve in the fuel pump, a leaky fuel injector poppet or a leaky fuel pressure regulator. My guess would be the fuel pressure regulator.
After you changed the fuel pump in your 97 silverado it floods out at an idle any ideas?
Check your fuel pressure regulator. $40-$50 is what it will roughly be. Should be somewhere on the top side of the engine connected to your fuel injector rail. That would cause your flooding problem. Shouldn't be hard to do on your truck.
What problem would you have if your 1992 Chevrolet Cheyenne 1500 is not getting enough gas to keep it idling?
Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator.
How do you check if a 92 accord fuel pressure regulator is bad?

What would be wrong with a 92 tracker pumping way too much fuel through the injector I replaced the injector-ecm-fuelpump relays-and pressure regulator and yet it still dumps excess fueL AT injeCTOR?
i would check the wires, you might have a short to power which would keep the injectors open all the time.
2006 Chevy silverado 1 injector does not work is that a fuel pump problem?
No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
What is wrong when the engine is not getting fuel pressure but the fuel pump and filter are OK?
Check three things: Fuel pump relay, and fuel pump inertia cut off safety device if equiped. check for 12 volts at the fuel pump to rule out faulty connector or wiring. Plus you need to check if the fuel injector if stuck open and also the fuel pressure regulator. this is on a 2000 kia sportage and no cut off safety switch,where is the pressure regulator located
What does code 25 mean on 1995 Aspire air bag light?
code 25 -refers to a short or open circuit between the solenoid valve to ECM.possible broken fuel pressure regulator or short circuit from solenoid valve to fuel injector main relay. check selenoid valve.(fuel pressure regulator control solenoid)
What would cause the loss of fuel pressure if your 1997 Chevy s-10 sits for a couple of days?
You could have a leaky fuel injector or a leaky fuel pressure regulator or a faulty check valve in the fuel pump. My guess would be the fuel pump is at fault.
How do you check the Fuel Pressure Regulator on a 1997 S10 Blazer?
connect a fuel pressure gauge to the port at the back. turn key on and check for pressure,watch for pressure drop if it drops immediately regulator is leaking.on4.3 reulator is under upper intake plenum
Why does Ford Expedition start slow?
Presumably you mean slow cranking. Check for weak battery or bad starter. If not slow cranking so much as long cranking time check for loss of fuel pressure overnight using fuel pressure gauge. If so, suspect leaking injector or possibly leaking regulator.
What causes a truck to have black smoke coming from the exhaust?
Black smoke is a sign of a vehicle running rich. I would check for a bad fuel pressure regulator, bad fuel injector or very plugged air filter. A fuel pressure test could tell you much.
