Do you mean the Fuel Pressure Regulator?
Otherwise a fuel pressure guage looks like a large dial indicator on one end and a rubber hose on the other.

SOURCE: olds alero 2.4 idle fuel pressure

most likely idle air control sensor or low engine coolant I know sounds funny but IAC uses coolant to regulate idle. Idle air control valve or throttle body positioning sensor.

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.

2003 Oldsmobile Alero starts and then dies. I've put new crankshaft sensor in it and fuel filter. Battery is good and the fuel pump is working. The security light isn't on, what else could it be?

Question edited for clarity and typos.
Question moved to model category.

It is a known issue. Fuel pumps can work, but not provide enough pressure, so you need to test with a pressure gauge. There is also a Pressure Regulator. Have a read of this.

2004 olds alero. new fuel filter and plugs. still wont start.

Did you check for spark at any ot the spark plug wires/ coils? If there is, check for fuel pressure at the fuel rail. Take the port cap off and connect a fuel pressure gauge. If one is not available, with a pocket screw driver deppress valve at port and observe if fuel pours out. If no fuel comes out at all, check your fuel pump circuit. Check for good ground and power at fuel pump connector. If power/ground are ok, replace fuel pump. If spark and good fuel pressure is present, there is the possibility of engine mechanical issues(jumped) timing chain). Also, a plugged catalitic wont let engine start but its very unlikely thats your problem. Start with your basics: spark, fuel, engine mechanical and catalitic.

1999 Olds Alero will not start until press is released in fuel injector rail

It could be that the fuel pressure is too high. This COULD cause the injectors to not fire when they are triggered. Once you bleed the pressure and the car is running, there is enough flow to keep the pressure at a manageable level. I would get a fuel pressure gauge and check the pressure at the rail. You may find a new fuel pressure regulator will fix your issue.

I installed a used fuel pump in my 2002 alero, the gauge now reads a 1/4 less then it should. How do I fix it?

You must have bent the arm of the sending unit, remove it and and match it up to the old one.

ETS malfunction

If the garage put a fuel pump in your fuel tank, and since then the gauge doesn't work, I would take it right back for that issue. The sending unit is what the fuel pump is attatched too, and controls the gauge.
