After fueling up my car will not start. I must turn it over 5-8 times before it starts. Then when it starts it will die unless you have your foot on the gas. It runs great the rest of the time & start on the first try (unless I just got gas).

no fault code where? on the Pro OBD2 scan tool screen>?

tow it there.?
bravo that, first post ever with fast right foot test, you are on the ball.
ok, that means this.
1: it's not losing 12vdc power to run the EFI. all lamps are not dim.
2: the fast foot test, implies to me, spark is ok, (unless one cylinder shut down, a bad COP?. but the scanner will see that for sure and did not. Gross misfire, is never unreported by the scan tool. (PCM)
gross enough to stall the engine.
so fueling issues.
id check for flooding or starving for fuel. and bad fuel.
Ok so my guess, is its losing fuel pressure or you got bad fuel.
try putting some injector cleaner into the gasoline tank because sometimes your fuel injectors do get clogged up and needs to be cleaned to allow the lower 87 octane through the injectors. Some of the times that the timing belt has been changed and misses with the timing with the piston heads and valves which opens and shuts while the gasoline fuel is being put into the piston heads chambers so if your timing is off would cause this similar problem as well.
I say dont accept vehicle back form the dealer, till its right. Sounds as though the throttle position sensor orMAS is bad. The dealer really should be able to fix it.
If it dies with your foot on the gas cruising you prabably have a bad fuel pump or maybe a bad relay if its a fuel issue.. Your symptoms are common for defective pump. This is an expensive job to do. Get a dealer part. Toooo many times we get defective aftermarket pumps and have to do the job twice if not more. Chevy's are real critical on what the fuel pressure should be.
