    Similar problem. Truck will not start if it sits more than a day, sometimes over night. Spray some fluid in and it starts right up and runs fine. But I can't hear the fuel pump running when I turn the key on. I have replaced the fuel pump relay. Any ideas? Thanks.

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.

If you have already checked the relay and fuse then have someone bang on the fuel tank hard while you crank the engine, if it starts then you know you have a bad fuel pump.

My 1997 chevy tahoe is hard to start, I changed the fuel filter and spark plugs but it still takes a lot of cranking before it will start


the pressure regulator may be leaking. pull he vac line and see if its wet. wet is bad. Also these fuel pump connectors are known to overheat from poor connections. Do a search on gm fuel pump repeat failures and overheating connectors. Also the fuel pump could be leaking down so the line needs to be primed. Try cycling the key about 3 to 5 times before you start it. The pump will prime for 3 seconds each time before shutting off. If this helps the problem is the fuel pump.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.
