You should have about 40-50 psi on fuel rail. Is there a clogged fuel filter in the line? In line filter installed properly?
Is the fuel pump any good?

99 Bonneville no fuel from fuel rail


My first guess would be that your fuel pump has died. This is evident buy having no pressure at fuel rail. Check this way, put key in ignition and turn to on, if you hear a whurrrrr noise in back of car your pump is good, if not change the pump. I am assuming all was working before. GOOD LUCK FRIEND.

If you know for a fact the pump is getting power and ground, and nothing is coming out of the line before the filter, then yes the line could be clogged up.

FIRST NEED TO RELIEF FUEL PRESSURE REMOVE GAS CAP RELIEF GAS PRESSURE IN FUEL TANK.THEN REMOVE FUEL PUMP RELAY THEN START ENGINE UNTIL IT DIES LACK OF FUEL,CRANK ENGINE OVER FEW MORE TIMES MAKE SURE FUEL OUT OF FUEL LINES. THEN YOU NEED TO REMOVE AIR CLEANER CROSS OVER TUBE ABOVE FUEL RAILS. DISCONNECT LINES AT THE ENDS OF THE FUELS RAILS ASSEMBLY. MARK AND DISCONNECT THE FUEL INJECTOR WIRE HARNESS CONNECTORS. REMOVE THE FUEL RAIL RETAINING BOLTS, DISCONNECT THE VACUUM LINE FROM THE FUEL PRESSURE REGULATOR. REMOVE THE FUEL RAIL ASSEMBLY FROM THE ENGINE. IF YOU HAVE AUTOMATIC TRANSMISSION REMOVE THE THROTTLE PRESSURE CABLE AND BRACKET TO REMOVE THE FUEL RAIL ASSEMBLY.TO REMOVE FUEL INJECTORS JUST REMOVE CLIPS THAT RETAIN FUEL INJECTORS IN FUEL RAIL. BESURE GO TO DEALERSHIP BUY NEW FUEL INJECTORS O - RINGS.APPLY A SMALL AMOUNT OF ENGINE OIL TO THE O - RINGS TO AID IN INSTALLATION. TORQUE FUEL RAIL BOLTS TO 100 INCH LBS.

If the replacement pump is only producing 10 psi, something is still wrong with the fuel system. The pump may be defective, though new.

How do I replace the fuel pressure regulator on my 96 pontiac bonneville? Is it something that is recommended for a mechanic, or can I do it myself? Is it causing my car to stall?


Well its easy to check find the regulator on the fuel rair next remove the vacuum line and see if there is any gas in te line if not have some one start the car if the regulator starts leaking gas out its shot. Its a easy repair take the vacuum line off loosen the big nut on the regulator and remove the smaller hold down bolt now becarefull at this point the fuel rair is under hight pressure so put a rag over the regulator or put on some safety glasses and start to wiggle or pry the regulator from the fuel rail. When u get it out match it up to the new one and make sure all the old o rings are removed from th fuel rail put the new one in start the car and check it for leaks.
