How do you replace the fuel pressure regulator on a 1997 Cadilac Devile? Thank you in Advance.

 

Well I have a friend who works for GM and he gave me the replacement procedure for the fuel pressure regulator. One remove the gas cap, second remove the fuel pump fuse, third start the car let it run until it stops, keep starting it until it will not start anymore. Then put a cup over ther pressure release rail to catch the gas and press the release valve until the all the pressure is out.

Once this is done use a needle nose plier or pliers to remove the clamp over the fuel pressure regulator. Grab and pull the fuel pressure regulator out of the value area. Put the new regulator in and clamp it down.Put the fuel pump fuse and gas cap back in place. Start the car.

That is it, guess what that was my starting and stalling and backfire problem. Thanks to a GM worker.

 

also to check for bad fuel regulater pull of va*** hose and check for fuel... had same problem with starting and idle but i also had a blown seal in my intake manifold also i had to replace that
