I cant get any fuel to the motor would it be the fuel regulator or fuel pump?

If your fuel pump is working but not delivering fuel to the engine, it could be due to a few different reasons. Here are some possible causes and troubleshooting steps to take:

1. Clogged fuel filter: A clogged fuel filter can restrict the flow of fuel to the engine. Try replacing the fuel filter and see if that solves the problem.
2. Fuel pressure regulator malfunction: The fuel pressure regulator regulates the pressure of fuel delivered to the engine. If it's malfunctioning, it may not be delivering enough fuel to the engine. A mechanic can check the fuel pressure regulator and replace it if necessary.
3. Faulty fuel pump relay: The fuel pump relay is responsible for turning on the fuel pump when the engine starts. If the relay is faulty, it may not be sending power to the fuel pump, even though the pump is working. You can check the relay by swapping it with a known good relay of the same type.
4. Clogged fuel lines: Fuel lines can become clogged with dirt or debris, which can restrict the flow of fuel to the engine. A mechanic can inspect the fuel lines and clean or replace them if necessary.
5. Bad fuel pump: Even though the fuel pump is running, it may not be delivering enough fuel to the engine due to a malfunction. A mechanic can test the fuel pump to determine if it's functioning properly and replace it if necessary.

In any case, if you're having trouble getting fuel to the engine, it's best to have a qualified mechanic diagnose and fix the problem.

I cant thin of a good reason to perform a "fuel pump reset" if there were such a thing?
Understand, the fuel pump is simply a tiny motor in the fuel tank that pushes gasoline out for the engine to use. It has no memory, no settings, or adjustments (for the most part, some newer ones do regulate w a duty cycle, but the pump is still a simple motor).
If you are having problems with starting or acceleration and it may be fuel related, the best thing you can do is get it scanned and or tested mechanically by a technician with access to an enhanced BMW scantool.
As to the fuel pump reset, there really isnt such a thing...fuel pump;s always work with the kjey and engine rpm UNLESS something breaks, or the alarm/theft system disables fuel. Thjere are no fault codes that turn off the fuel pump on your vehicle, so no memory to erase to ruen it back on or change its operation.

first check the fuel filter. check before and after the filter if you get fuel before it then check after it, no fuel before go back to the pump. if you get fuel after then go to the fuel rail on the motor. open the line before the pressure regulator, if you get fuel then check after the regulator, if none after then the regulator is bad, if the regulator is vacuum assisted check your vacuum.

you cant just steel power.you have to have fuel pressure regulator conected with fuel pump relay and pump itself.best way would be to install fuel tank from MK4 with el.pump inside,add relay conected with ignition switch and fusible power from battery

Hi Teresa, There is no valve on the motor to check the fuel pump pressure. The way that the testing is carried out is to fit a test meter onto the inlet feed into the fuel rail with an extended banjo bolt and special adapter with the use of gasket washers (copper or aluminium). Once connected, start the engine and let it idle. the pump pressure should be a minimum of 3.6 bar and a maximum of 4.8. Cut the engine and the pressure should be maintained for at least four minutes before any drop is noticed. If there is a drop the fuel pressure regulator is suspect. Regards John

the fuel pressure regulator is located on fuel rack, top of motor.follow the chrome fuel lines on top of motor to the end next to drivers side of motor and you will see a round cylinder. that cylinder is your fuel pressure regulator.make sure to let pressure off those fuel lines before removig the regulator. you should have a valve on the fuel rack that looks like a tire valve, insert something pointed into that valve and gas will come out.that's the way you releive the pressure from the fuel pump.be advised that gas should come out of that valve, cover your eyes and face.

This vehicle is most likely a returnless system,only one fuel line to the fuel rail. If it is returnless the fuel pressure regulator is part of the fuel pump module in the tank.

If the fuel pump is working, fuel should be reaching the motor. Otherwise, you need to check the fuel pressure regulator. Depending on the location, if it is before the motor and the regulator is bad, then the fuel wont pass through.
Did you check for spark from the wires? My experience with Chevy Cavaliers is usually electrical but not fuel related.
