SOURCE: 1997 chev. suburban new fuel pump and regulator WILL NOT START

Check fuel pressure and fuel flow, If the pressure is lower than what is recomended injectors will not function correctly , no start condition (trys real hard though)

SOURCE: vacuum line for fuel pressure regulator 98 Tahoe

Was there a hose on the old one? If not, you don't have one. It is most likely your fuel pump if you are not getting fuel.

SOURCE: 1997 Tahoe wont start, has spark, and fuel pump works

Your Tahoe does have a vacuum line connection to the regulator. It's also possible the regulator itself is bad,

I change my fuel pump for the third time, but this time I put in the original factory one, but my truck won't start and I check for pressure of the fuel filter but it won't squirt out gas. Do I need to...


First off you can simply check a fuel pump with a 9 volt battery by hooking up the negative end with one side of the battery and the positive with the other side. After making sure its working you check it with the vehicle. If theres no power this means either you have a short somewhere, or your fuel pump relay has gone out. I don't believe the pump would need to be primed, I would recommend making sure you are getting fuel to the filter or fuel injector rail/carburetor before trying to start it repeatedly.

1998 chevy tahoe 4x4 wont start. not getting fuel to throttle body. its not a fuel pump relay i tried it. it will start if i pour gas in the throttle body


fuel pump or fuel pressure regulator. When you turn the key do you hear fuel pump run? If not odds are the pump is bad.

My 95 tahoe starts but dont stay on. Fuel wont stay pumping from tbi. Just swapped a motor from 80's camaro. Was running real good in box chevy perfect. Now fuel wont stay flowing out of injectors. Already...


did you install the oil pressure switch origional to the tahoe? The tahoe uses a low oil pressure shutdown, instead of an inertia switch to shut off the fuel pump in the event of an accident. If the pressure circuit does not close within 3 seconds after the engine starts the fuel pump shuts off. This is in case the truck is on its side or upside down the pump will shut off.

that truck has a fuel pressure of 43 lbs there is a fuel pressure valve need the fuel regular if you press the valve while trying to start the truck you should get fuel if not check the fuel filter to see if it is blocked

My 1997 chevy tahoe will not start without starting fluid. I hear the fuel pump running and have changed the fuel pressure regulator already and the fuel filter. The pump is only a year old. Have checked...


IVE HAD PLENTY OF THESE GO OUT EVEN A MONTH LATER. AS FAR AS THE STARTING FLUID JUST TRY AND CYCLE KEY BUT KEEP IT FROM TURNING STATER OVER. TURN ON AND OFF ABOUT 3 TO 5 TIMES IT SHOULD BUILD ENOUGH PRESSURE TO START. TO START MINIMUN PRESS IS 55PSI.

Dont know whether its the fuel pump or something else


How did you determine its not the fuel pump?It could be the fuel filter but I dont think so.Your truck requires a certain amount of fuel pressure to start and a different amount to run properly.You would have to check what your fuel pressure is to say its not the pump.It should be something like 65 psi to start and 55psi to run.Even though you can hear the pump come on when turn the key it might not be putting out enough pressure to start the truck.I realize im a little late with this post but it might helpfull to others.
