The car turns over and starts it will only run for 30 seconds then shuts off?

Put a fuel pressure gauge on it and watch while running , if fuel is the problem then pressure should drop below spec. as it dies.

Who did the work repalcing everything? They may have miss connected a line and also the electricals. Everything has to be squared away for it to run good. Pull the fuel line at the rail before the injectors. Put a container under the line (Pressing the plastic clip and gently pull away from the line releases it) and turn on the ignition and see how much fuel comes out in 30 sec.? Do put a gallon jug, might run over or even bigger. I do not know how many Gallon Per Minute they are rated for.
