HELP FAST!!! 3.8 Supercharged FUEL problem

I did many upgrades this past weekend. 2 include bigger fuel injectors and bigger fuel pump. Drove it to gas station, put gas in and didnt start. Now after i start it, it will stall out after a minute and wont start for a little while. So i put stock fuel injectors in and stock fuel pump, still the same thing happening. There is NO gas coming out of the valve on the fuel rail. Whats going on?!?!? I also installed a turbo kit and a set of rockers, but i do not think it would be related to these 2 things unless it would need a new tune up due to turbo install, PLEASE HELP ME!!!

Welcome to AF.

It would help to post the year of your GTP. Sounds like the fuel pressure is low. Have you checked the fuel pressure? Based on your symptom a common problem is the fuel pump resistor. When bad it is prevents the fuel pump from going into high speed mode. There is a post at our Tips & Maintenance section on how to bypass for troubleshooting purposes.

The car is a 2000, I will go ahead and bypass that tommorrow and let you know what happens, I put a new one of those on about a year ago, thanks.
