I just build a new Coyote for my S197 (2013 GT) as I threw a rod in my original GEN1. The block is a GEN2, heads GEN2, Intake cams GEN1, Timing components GEN1, GEN1 intake, E85 tune, GEN2 Injectors, LTH, etc.
After installing this engine I am having all sorts of problems getting it started. If it fires up it sounds like it's running on 3 cylinders at best. Extremely rich. After a while raw fuel will start coming out of the X pipe and when I pulled the intake yesterday it had a 1/2 cup of fuel in it when I tipped it over. I don't know how I didn't hydrolock the engine but I got lucky. How the fuel got in there is yet another mystery.
I replaced the MAF, cleaned and dried the intake, blew out the cylinders, and cleaned up the plugs and reassembled. I made sure all vacuum ports were plugged up and tried to start it and again I got the same error and a very rough start.
My tuner has confirmed the tune is correct for my car. I'm kind of stuck as to where to look next. I have a NOID light coming tomorrow so I can check the injectors to make sure they aren't stuck on.
Do I have a ground problem? I only know of the ground on the passenger side of the engine attached to the motor mount and the ground next to the PCM. Is there another I am missing somewhere that could be causing this?
Any help or even a nudge in the right direction would be extremely helpful.
Thanks
