Do you get a security message or a lock through a car flashing when this happens? DO you have anything aftermarket installed?
Customer: replied 2 years ago.
we do not get anything
Expert:  GM Tech (Cam) replied 2 years ago.
OK, in the fuel tank is a pump, that pump should turn on for 2 seconds when you turn the key on. It should be a very subtle hum, Do you hear that or does it sound much hight pitched and VERY easy to hear?
Customer: replied 2 years ago.
we do not here anything
Expert:  GM Tech (Cam) replied 2 years ago.
OK, if you press the fuel, does it stay running longer? Also are you looking to repair this yourself or are you looking only for costs and such to get it fixed?
Customer: replied 2 years ago.
no it does not stay running when you press gas pedel if it is fuel pump do you have to drop the tank
Expert:  GM Tech (Cam) replied 2 years ago.
Yes, if the fuel pump is indeed faulty then we do need to drop the tank to replace. The test we need to do is measure the fuel pressure. This is done at a small port on the engine. Spec for this engine is 50-60 psi. If it drops below that then its a faulty pump .
Customer: replied 2 years ago.

Expert:  GM Tech (Cam) replied 2 years ago.
Its a black cap in the area shown in the yellow circle.
