97 Grand Prix Fuel Pump

Hello Everyone, I have a 97 Grand Prix Supercharged GTP. My fuel pump stopped working so I went and bought new relay and that fixed it for about a week. Parked over night and then it stopped working again, I believe it is the PCM since the relay and fuel pump gets power for about 2 seconds and then shuts off. Please give me some advice.

Thanks, Chris
 


Did you try the relay trick to put the pump into "High speed mode".

The PCM is not going to cause a problem like this.

That didint work, the reason I was thinking it was the PCM is because of the picture attached. In the bottom right it shows the PCM with a fuel pump relay control.
