Looking for some help here KA Great Minds. I did not removed the fuel rail only the injectors to install my new 370cc SR injectors. I have a SAFC2 and I have corrected the Lo and Hi to -27% across the board all RPMS. And it didn't start, Just turns over and over occasionally with a hick-up like it wants to start. I went to the Parts store and bought new seals and replaced them on the injector only, and still does the same thing. I have looked around on here and other forums and I am still looking now. Please any help would greatly be appreciated.

Could be flooded or is there any issues with the MAF sensor?

As far as I know the MAF is good, I didn't change it yet. I do have a n62 with me but i need a pig tail for it first.

why did you install bigger injectors? hopefully theres a valid reason and your motors not stock.

first things first see if the injectors are spraying fuel. then check safc wiring and go from there.

I have Everything for my turbo install, I just dont have the time for my car to be down for that long at once. So i figured I would install the little things now, (kinda pre-turbo) so that I'm not trying to install 50 things in a short amount of time. Yes the injectors are sprying fuel and alot of it. I do have the SAFC2 wired right. Once i installed the 270's back in it started fine, So I think its flooding, I just have to get it start with the 370's so i can tune it with my wideband.
