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.
