Car will crank but will not start. Gauges on gas or not working just the CEL Will illuminate. The car will start for a few seconds and then die.

Hello mfridge, I would advise that you don't replace any more parts and focus on identifying the source of the problem. I would start with checking for any stored diagnostic trouble codes and check the fuel pressure. There are so many possibilities...further guessing will only result in wasting $$ and the likelihood you will fix it is very low. If you pull the codes you can post them here and we can provide further help. Good luck
