Greetings and Welcome to Just answer.
The way to clear the flood is the same in these as it is in the old vehicles. Hold the fuel pedal to the floor while cranking and only release it when it fires and starts to rev up.
If that does not work, try a reset. Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.
Do you have a code reader or scan tool?
Ok, codes would help alot.
Reply back tomorrow.
I just read the codes on my car, it has 2, one is P1516, throttle actuator control module and P2102 something about the same thing. Hope this helps

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
A vehicle may be brought into the dealer for a reduced power message, and DTCs P0120, P0220, P1516, P2101, or P2135.
The Throttle Actuator Control (TAC) / throttle body type trouble codes, may be caused by a loose wiring crimp at the throttle body connector, or a broken throttle body circuit.
Complete the current SI diagnostics for any symptoms or trouble codes found. If a intermittent T/P or TAC module type code is occurring complete the inspections below.
If a terminal crimp or a broken wire has been found, repair or replace only the circuits involved. There is a throttle body pigtail connector available through GMSPO, but installing this pigtail connector may cause other intermittent TAC module/TP codes at a later date. If this pigtail must be used, please follow the SI procedures for Splicing Copper Wire Using Splice Sleeves. (the proper Kent-Moore crimping tool must be used for this repair)
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
#06-06-04-007: Diagnostic Information for LS2, LS4 and LH6 Engines for Diagnostic Trouble Codes (DTCs) P0606, P0689, P1516, P1682 and/or P2176 that may have Set Due to Low Battery Voltage Condition - (Feb 2, 2006)
This bulletin is being published to aid technicians in the diagnosis of the following DTCs:
The above DTCs may have set under a low battery voltage condition during or prior to vehicle cranking, then starting. If these codes are present, and a low battery condition exists or the customer indicates that the vehicle has experienced a low battery voltage condition, the technician should do the following:
Then I suspect the wiring issue in the first bulletin I posted.
