I recently upgraded a bunch of parts on my engine. After we finished installing the cam, LS2 heads, oil pump from Melling and other stuff we started the car and she started right up. Granted it was a little rough but I know that it's not tuned yet and that's why. I was running the car on the stock fuel rail and stock injectors.

I recently istalled 42# injectors and a billet fuel rail from metco motorsports. Now the car wont start. This is my very first fuel system to swap out. I'm going to install a racetronix fuel pump in the next couple of days.

My question: Is it normal for the bigger fuel rails and injectors to prevent the car from starting back up?

Will the fuel pump help or hinder the situation?

Is it likely that the fuel pump will help the situation before I get it tuned?

I really appreciate any help I get. Thank you very much for your time.

You need to get the computer re-tuned for the bigger injectors.

You nearly doubled the fuel flow & that amount cannot be compensated for without a tune. Do not attempt to run the car until you reprogram.

A new pump will not change this issue.

Those rails look sick! I emailed them about an LS3 application!
