Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

I dont know how much help this will be, but I'll offer it and let you be the judge.
Ive had this issue before in a different GM vehicle, a Pontiac Grand Prix. The issue turned out to be that the voltage from the battery was low due to corroded terminals. Once that was cleaned up and the voltage restored to normal, the key came out. Come to find out that this was a common issue in that vehicle, voltage goes low, you cant remove the key.
Now, on my vehicle and since yours is a GM product as well I will assume it will hold true for your vehicle too, there is a small hole on the bottom side of the column right in the area of where the ignition key cylinder is. If you have this, you can take a small tool like an allen wrench and push it up in there and that will press on a release mechanism that should allow you to turn the key back to its release position and pull the key out.
Hope this helps.

Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

Testimonial: "it was the fuel pump thank you"
You need 3 things.
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.
Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.
