Fuel Pressure Regulator replacement!

Is there anyone who can walk me through replacing a fuel pressure regulator in a 1997 Grand Prix GTP. The car died on me, and would start then stop right away. I bent back the tab on the fuel pump resistor and it started and stayed started, then replaced the resistor and it died again. I haven't driven it since and was told to replace the regulator. Is this true and can anyone help with directions. Thanks.

Before you waste any time and money, the best thing to do is test the fuel pressure at the fuel pressure regulator (FPR) Schrader valve. That way you are checking the fuel pump, fuel filter and FPR.
Your GTP should read around 45 - 55 psi of pressure with the vacuum line connected. With vacuum dis-connected it will read somewheres around at least 52 psi. There shoud be no more than a 4 - 7 psi difference with vaccum off or on. If so, then the FPR is bad.
As for changing the FPR, it is very easy. There is a c-clip that holds it down on the bracket on the injector rail. Remove it and the FPR will come off by pulling up and out. Be sure to bleed off pressure first before removal and make sure your battery negative is disconnected before working on the fuel system Good Luck!
