I brought my car to a shop they have replaced fuel filter, fuel pressure regulator, fuel pump, fuel injector, & the ICM, but have not fixed the problem, it starts fine and idles great but as soon as I put it into drive or reverse, or give it gas it stalls. Can someone please help? it's a 2.2 liter 4 cylinder TBI

2004 Lincoln aviator looses fuel pressure after it has been parked for 4-6 hrs. have to turn the ignition on (not Start ) 7-10 times then the vehicle will. start. replaced the intank fuel pump.fuel filter...


i would check the fuel pressure. see how fast the pressure goes down. most cars i have worked on it dosnt take that many key-ons to get fuel. a fuel pressure regulator could be leaking. there is a check ball in the pump to keep the fuel from draining back. since the pump is new, i would check the regulator and poss. the injectors. its poss. for an injector to leak or stick open

Engine loses power while driving. It acts like its outta gas but it dont die, if I slow down or stop it works fine again. I put 2 used fuel pumps in it then I put a new fuel pump in it. All 3 pumps read 35...


Fuel pressure regulator maybe . Do you know where it is on the fuel injector rail . With the vehicle running pull the vac, hose off . Does the rpm go higher ? Is there fuel leaking out the end of the regulator ?

No/Low Fuel Pressure after replacing in-tank fuel pump & filter


Need to have the fuel pressure checked at fuel rail to know for sure if there is a fuel pressure problem for sure. There may be a in line filter as well, you can also do a check of the pressure regulator by pulling the vacuum line off of it then try starting the car with it off and see if it runs, if it does the regulator is bad, but IF it doesnt run doesnt necessarly mean it is good, a lot of fuel filters have a bypass wich allows the gas to bypass the filter when it is full bad thing is the debris can then plug the injectors causing problems, or there could be a loss of signal to tell the injectors to give fuel to the cylinders from an electrical or a sensor failure. So it is best to test the pressure to know for sure if it is in the fuel line or the injectors if it is truly being starved of gas. hope this helps

How to change a fuel pressure regulator in a 1997 pontiac grand prix


GM Century/Lumina/Grand Prix/Intrigue 1997-2000
Fuel Pressure Regulator - Removal & Installing

The fuel pressure regulator is a diaphragm-operated relief valve with fuel pump pressure on one side and regulator spring pressure and intake manifold vacuum on the other side. The regulator's function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.

The fuel pressure regulator is serviced as a separate component. When servicing the pressure regulator, make sure that the O-ring back-up, large O-ring, filter screen and small O-ring are properly positioned on the pressure regulator.

REMOVAL & INSTALLATION
The need to work as cleanly as possible cannot be over-emphasized. Even the smallest amount of dirt, if allowed into the fuel pressure regulator and/or the fuel rail, will find its way to the fuel injectors. The nozzle openings of the injectors are very small. Keep hands and tools clean. Clean the areas to be disconnected with a suitable solvent. Carefully cover open fittings and connections to keep out foreign material. Dirt in the injectors almost guarantees a clogged fuel injector and engine performance problems.
3.1L and 3.4L (VIN E) Engines
  1. Disconnect the negative battery cable.
  2. Relieve the fuel system pressure using the procedures found in this section.
  3. Remove the upper intake manifold assembly. Please see .
  4. Disconnect the vacuum line from the pressure regulator.
  5. Remove the regulator retaining screw and remove the retainer bracket. Using a clean shop cloth to catch fuel spillage, carefully pull the regulator from the fuel rail. Twist the regulator slightly while removing to ease removal. Discard the O-ring.

To install:
  1. Clean all parts well. DO NOT use shop compressed air to test or clean a fuel pressure regulator. Clean the fuel pressure regulator screen, if necessary. DO NOT immerse the fuel pressure regulator in a solvent bath or it will be damaged.
  2. If the filter screen has been contaminated, it should be removed and the pressure regulator replaced.
  3. Lubricate a new pressure regulator O-ring with clean engine oil and install on the regulator inlet.
  4. Install the fuel return pipe to the regulator.
  5. Install a new retainer and spacer bracket into the slot on the fuel rail and install the pressure regulator to the fuel rail. Tighten the fuel return line nut to 13 ft. lbs. (17 Nm).
  6. Connect the vacuum line to the pressure regulator and install the retainer screw. Tighten to 76 inch lbs. (8.5 Nm).
  7. Inspect and verify that the retainer and spacer bracket is engaged in the slots in the fuel rail. Grasp and pull on the regulator to ensure that it is properly seated.
  8. Install the upper intake manifold. Please see .
  9. Connect the negative battery cable.
  10. Inspect for leaks using the following procedure:
    • Turn the ignition switch to the ON position for 2 seconds.
    • Turn the ignition switch to the OFF position for 10 seconds.
    • Turn the ignition switch to the ON position again.
    • Inspect all areas for fuel leaks.

Hope this help (remember rated this).

1999dodge p/u wont go over 40 runs great at idle new plugs ,wires,cap,rotor.acts like no fuel


Replace fuel filter, because it is cheap & easy, and may solve problem.$20
Fuel injector cleaner in the gas tank $5...listen for even ticking sound in injectors at idle and higher RPM. Injectors can be services/or replaced easily. $60 each
Fuel pressure regulator, next to fuel rail, may be going out...$75
If you have an in-line pressure guage, you can meause the fuel pressure to see if is within specs.
