No start Tahoe w/BBC

[camaro76_454]

Hey Everyone,

I've just bought a Tahoe from a guy who dont know anything about cars or trucks. Well, it had a problem with the starter so I fixed it and the engine start for the first time but it was so rich.
on the second day, I tried to crank it but it wont start. I took the plugs out and replaced them with the same plugs but still wont start.
Its a BBC tall deck with Brodix heads, brodix manifold, Fast ECU Fuel injection, RC 58 lb injectors, Doughs 2 1/8" headers, Vortech V-4 Spercharger Kit,TCI 4L80E 4X4 Tranny Kit and 9" rear end
I bought the CD and the cable from Fast and in the Tuner says 605cid.
I tried to lean it and no better.

anyone got any ideas where to start or what to do?


Thank you,
