I have a '96 Blazer 4x4 with 156K miles. It runs fine - no hesitation, no
loss of power, good acceleration. However, when the tank is less than 1/3
full and I park it on a downcline (front lower than the rear), it won't
start. AND if I park it on a downcline with the engine running, it will die
after a couple of minutes. When this happens, I can hear a "whir" coming
from the gas tank area. I assume the noise is the fuel pump.
One guy told me that the fuel pump assembly needs to be replaced. Not sure
I agree with that. If the fuel pump were bad wouldn't I have problems with
hesitation, acceleration, loss of power, etc?
Any helpful suggestions will be appreciated.
