No pressure at fuel rail on 88pontiac grand prix can not hear fuel pump kick on

You need to test the fuel pressure that the fuel rail in the engine. Test it with just the key on, and then test it with engine running. If it is within specs you need an auto electrician with a pro grade scan tool computer to read the live data as the event happens.

Oct 5, 2010 - Check fuel pressure with a mechanical gauge, should be above 40psi, and when you "blip" the throttle it should go up 5psi or so. Some pumps are ...

Find the fuel pressure regulator on the fuel rail. 3.4 ant 3.1 liters it will be on the front rail on the drivers side near the throttle linkage. On a 3.8 it will be on the back rail about in the midle. Remove the vacuum hose from it and start the vehicle. If gas comes out it is bad. if no gas comes out than you will need a fuel pressure gauge to see if fuel pressure is holding. If it is not than the fuel pump is the next most likely suspect.

Check for pressure on the fuel rail at the schrader valve. Which is located on the rail. My guess is you have low fuel pressure and have faulty fuel pump. Pressure should be around 50psi.

Check Your fuel pressure, sounds like a fuel pump problem. Good Luck

Could be ignition control module or fuel pump, if you don't have spark to spark plug's, control module, also check for fuel pressure at fuel pump pressure port, port will be on fuel rail.

you should be able to hear it, if not install a pressure guage on the fuel rail,

two things i can think of, 1) a restricked catylitic converter. 2) faulty fuel pump or injectors. check your fuel pressure a the fuel rail to test the pump. a plugged cat. will cause back pressure in the exhaust, if the car is good and warmed up ( at night or very dark place ) look at the "Y" pipe attached to the exhaust manifold, if it glows a dull cherry red replace the converter.

the fuel pressure regulator should be on the feul rail near the injecters.it should have a vacum line connected to it.

it will not blow when ECM is disconnected, cause there is no power to the injectors when you disconnect the ECM. When you turn ignition on check for fuel pressure at fuel rail. Release pressure at nipple on fuel rail. If no pressure exists puel pump is shot. If there is pressure your fuel filter might be plugged.
