Fuel pump

Welcome to the forum, your taking your chances with a used fuel pump. Always use a gage and check fuel pressure when you suspect a fuel issue. Also, that spider fuel system, fuel pressure can be critical. Sometimes the fuel poppets get stuck open or closed.

Need to prime the system back up and get air out. Cycle the ignition key on 10 seconds, off 10 seconds, on. Several times. This will kick on and off the fuel pump, pushing the air out of the system. See if this helps.

If you mean how to disconnect fuel lines you will need a fuel line disconnect tool which most auto part stores should have.

Not even close. There are two totally different pumps for '94 models and neither one is the same as a 2001 model. GM is famous for constantly changing things.

All you got is 2secs to hear it come on than the fuel pump relay de-energizes-get a helper and you listen before the key is turn to run position

Hello

Replacement procedures for your vehicle's fuel pump are below..

REMOVAL:
Properly relieve the fuel system pressure.
Connect the negative battery cable.
Using the GM fuel gauge sending unit retaining cam tool No. J-24187, J-36608 (or equivalent) or a brass drift and a hammer, remove the cam locking ring (fuel sending unit) by twisting counterclockwise. With the locking ring released, carefully lift the sending unit from the fuel tank.
Remove the fuel pump from the fuel sending unit, by performing the following procedures:
Pull the fuel pump up into the mounting tube, while pulling outward (away) from the bottom support.
When removing the fuel pump from the sending unit, be careful not to damage the rubber insulator and the strainer.
When the pump assembly is clear of the bottom support, pull it out of the rubber connector.

(((A brass drift and a hammer can be used to loosen the fuel pump locking cam))

INSTALLATION:
Inspect the fuel pump hose and bottom sound insulator for signs of deterioration, then replace, as necessary.
Push the fuel pump onto the sending tube.
Using a new sending unit-to-fuel tank O-ring, carefully lower the sending unit/fuel pump assembly into the fuel tank.
When installing the sending unit, be careful not to fold or twist the fuel strainer or it may restrict the fuel flow.
Secure the sending unit by turning or driving the lockring clockwise and into position under the tabs.
Install the fuel tank assembly to the vehicle.
Connect the negative battery cable and check for proper pump operation.

I found this in online partsbook, about 318 bucks. You can get cheaper fuel pumps.

Hi:
Chances are the O2 sensor has nothing to do with the no start. It may be causing poor engine performance or bad gas mileage. As far as the fuel pump, you will need to check for power to it when the car won't start, or have it checked for fuel pressure. If there is no power to it, I would start with a fuel pump relay. If the pump is getting power and not working, it will most likely need replJoeaced.

Keep in mind, the pump is in the fuel tank, so make sure you don't hear it before trying to get to it.

When you turn key to On position-do you hear the fuel pump come on for a few secs? If not Check the 20 amp fuse see below if okay look for power at the gray wire at the fuel pump connector

You need to check fuel pressure with a gauge-

I took it to the mechanic thinking it was the fuel pump but was told that the fuel pump was fine just not getting power-How did he came about this-

Did he do a fuel pressure check by jumping off the fuel pump? And for you -Do you hear the fuel pump come on for a few secs when you turn key to run position.

No power could mean the fuse and fuel pump relay and pump itself
