SOURCE: 2000 gmc jimmy wont start fuel pump comes on and cuts off...

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

Changed fuel filter on my 05 Audi a4 3.0. Now I'm not getting no pressure build up by fuel rail


If the fuel pump check valve check valve is bad, the car may be unable to start. If the car does not start, turning the key so that it is one click away from starting, then repeating this process several times, may build up enough pressure so that the vehicle starts. If that is the case, the check valve is bad and needs to be replaced. check the fuel pressure regulater also. good-day ! If fuel pressure is low, disconnect the vacuum hose to the regulator. You should see an increase in pressure, if the regulator is not leaking. No change would indicate a bad regulator, check this first and get a fuel pressure reading on it to determine the pressure.

How do i know if my fuel pump is bad


The only way to know for sure is to put a fuel pressure gauge on the pressure regulater valve. when yo tuRn the key on ENGINE OFF the pressure should run at 50 psi when you turn the key off it should hold pressure for one minute, if not the regulator is bad, or the fuel pump check valve is not holding and this is not good. So the pump has to e replaced.

Ford pick up wont start


If it was the pressure regulator, the pressure would read high, low pressure is a weak fuel pump, in which case you have to drop the tank to change it, and if you haven't changed the fuel filter lately, now would be a good time to it, while the pump is being changed, ( that is if the fuel pump and filter is not all in one unit).

My 91 acura integra with a 95 gsr motor in it starts, then dies right away. I replaced the spark plugs, checked for spark through the wires, and checked to see if fuel was coming from the pump. Everything...


did you check the fuel pressur on the fuel rail with a gauge or did you just unplug the pressure reg..

also you should try replacing the fuel filter first... this is cheap 6-12 dollars autozone. just becuase the fuel pump is pumping doesnt mean it its enough. There mightbe a strainer on the fuel pump that might be plugged.

fuel pump check valve doesn't cause pressure loss, just hard starting cold, the check valve is part of the fuel pump, so to replace the valve u must replace the pump. do not use anything but the orig style pump, here is the part number from THE OE PUMP MAKER AT www.rockauto.com
