I recently bought the perrin fuel rail and now every time I try to start my car the first time it sputters and dies and start it again and it runs but when I step on the gas it hesatates I was thinking maybe if I buy the warlbro fuel pump this will help any suggestios please

 

Not sure what Mods you have but not sure why you need bigger fuel rail if your cars pretty much stock if it is stock. Sounds like it's getting to much fuel.

 

I have many mods and stage 2 cai,msd, sts, greddy type s bov,and others I can't think of

 

I also have the same fuel rail. I had the same simular problem in the beginning; i didnt let the fuel pump prime the line when i first recieved it; 2nd i let the 1st gear roll, w/o pedal, cause i had to been flooding "chambers" when i applied gas. The stock fuel pump supports up to 300hp's. Me, i switched out my fuel pump for 2 reasons; 1. was the fact that my goal is to push in or around 350+ hp (no more than 410 due to axle prob). 2. i dont wanna work the F.P. when my ECU ask for more fuel when im gunnin it...

Hope this helped
peace
