I just tuned up the car and did a coolant flush then drove the car down the road ran fine I shut the car of and when I went to start it back up it started giving me a hard time and then started blowing white smoke out of the exshaust a lot of white smoke I can not get it to start it cranks but wont start and if I get it to start it runs like crap and stalls out.

Hi ralph123, Welcome to 2carpros and TY for the donation

Check the oil if its mixed with gas if not-Check the cylinders if it has coolant in it-if so could be a blown head gasket cracked head or block or an intake leak. Let me know we start here

Why don't you use an OEM sparkplug with higher heat range that will burn off the oil in the combustion chamber to prevent from fouling that can be causing the hesistation.

Sounds like it- get it block and pressure tested to find out. Check the oil if its milkshake looking

Do below and get back with some results-

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

I have done all that everything was fine, if it was dumping a lot of anti freeze into cylinder 6 would that cause it not to start?

It would hydro lock-the piston cannot compress the liquid in it if both valves are closed-

Is the engine cranking over and will not start or just won't crank at all even if you hear the starter engaging the engine?
