The past two times I have put gas in my car, it takes me several tries to start up the engine. The check engine light turns on and my car shakes. The light ends up turning off once the car starts. We heard that it may be my fuel pump. What would the labor and parts be for this vehicle?
This is a CLASSIC symptom of an evaporative emissions issue. GM has had tons of issues with this system. Don't even think about fuel pump at this point. Read this post on how EVAP works.

Then read this post on service bulletins GM has issued on the EVAP system

I am having the same problem... My solution was to check for pending trouble codes, which is a sensor about to go out... Mine was a crankshaft sensor b trouble code PO385 and PO356.. You might want to check it out...I have 80,000 mile today also 03 deville V8 4.6

That's what was finally found by our Cadillac dealer as well. They charged us too much, though.
SOURCE: car turns over but won't start sitting for almost a year
muke sure it is pumping to filter when you chage it.

The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

First, obviously, put gas back in the tank.
Check the fuel pump fuse, (20 amp yellow fuse in the lower left corner of the group). If that is not blown, turn the key on and pound hard on the bottom of the fuel tank. The fuel lubricates the fuel pump, once it runs dry, the pump can lock up. Once the pump is immersed in fuel again, a sharp jolt will unstick it and let it pump up to pressure again. If it locks up for too long, the pump will burn out and need replaced.
We found this out by accident, got mad and pounded on the bottom of the tank and the pump jumped to life.
