Your Alero does not have a transmission dip stick. You do not need to check it unless it starts leaking.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

How to bleed the fuel line on a 2012 Chevy impala

There should be a schrader valve on the fuel rail up on top the motor before it gets to the injectors, relieve all fuel pressure, and then remove the valve core from the schrader valve with a valve core tool. Connect a small rubber hose over the schrader valve and put the other end into a small bucket. Cycle the key in the ignition, but do not start the car, and this will cause the fuel pump to pump small amounts of fresh fuel from the tank through the lines and out into the bucket. Do this as many times as it takes until the old fuel is out of the lines.

Location of fuel pressure test valve

Not sure about what engine you have, but here is the general procedure.

Open the hood. Disconnect the negative battery cable from the battery.
Look on the front of the engine and find the fuel rail. The fuel pressure regulator is on the right side of the fuel rail. Follow the fuel lines toward the firewall until you come to a Schrader valve with a black cap. Rotate the cap counterclockwise and remove it from the valve.
Wrap a shop rag around a small flat-head screwdriver and press the center pin in the Schrader valve - you have relieved fuel pressure when no more fuel comes from the valve. Install the cap back onto the Schrader valve. Hope that helps.

I have a 1991 Mazda 626 that wont start

Look at the top of the engine and locate the fuel rail on the injectors. There should be a Schrader valve on the rail. Take a small screwdriver or a nail and push in on the Schrader valve. Have the helper turn the key on and look for fuel pressure at the valve. If there was no Schrader on the rail, just loosen the fuel line for the same results. If there is no fuel expelled, check the fuel pump fuse and relay located in the relay box. If these are not faulty, the fuel pump has failed and is need of replacement.

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.

Fuel filter

At the rear of the car near the gas tank, you'll find the fuel filter. Simply unscrew it and screw on the new filter. Relieve the fuel pressure before removing the old filter. To do this, remove the gas cap and at the engine you'll find the schrader valve on the fuel rail, press it. The schrader valve is found on the fuel rail.
