Vehicle was fine until this morning, turns over with really good power sputters but will not start. Checked Anti Freeze overflow container it is not frozen, battery is good since the starter cranks engine with full power. Half tank of gas, have not had any problems before today. Did not idle to build up condensation etc.
Do you
have the same problem?

Locate the fuel pressure test port on the fuel rail. It will look like a metal tire valve after you unscrew the cap. Poke it to see if there is fuel pressure. Watch your eyes; it should squirt up a few feet. If there is no pressure, listen for the hum of the fuel pump for one second right after turning on the ignition switch. If you don't hear it, bang on the bottom of the tank while a helper cranks the engine. GM pumps tend to fail while you're driving. Chrysler pumps never do that. They fail by failing to start up when the brushes in the motor are worn. Jarring them often gets them started, then they will continue to run until you stop the engine. It could be weeks or months before this happens again.

If you DO hear the pump run for one second, check for spark during engine cranking. Holler back with your findings.

The temperure here in Long Island last night was below freezing like 17 F however the antifreeze is good and the gas is one day old with a can of anti freeze added could the below freez have created a problem or vapor lock.

Nope. I doubt you have a fuel-related problem. Did you check for spark? If there's no spark during cranking, grab a test light, ground the wire to the battery negative post, then back-probe the dark green / orange wire in the connector for the ignition coil, one of the injectors, or either of the small wires on the back of the alternator. You will see the test light turn on for one second right after turning on the ignition switch. What we need to know is if it turns back on when you're cranking the engine.
