LS3 crank but start only if I press the pedal
Hi and thanks in advance for your time. I installed a LS3 crate engine (with transmision package) all as stock. When i try to start, the engine crank but doesn't start but I press the accelerator pedal it starts. I checked fuel pressure and everything seems to be ok. Appears to be lack of air, so when I press the pedal open de throttle and the engine start. Do you think the same?
Any help?
PD. Sorry for my english, i'm from Argentina.

I just press the pedal a little and the engine start. I think in a problem of lack of air because when the engine starts it smell as if it was too rich.
The crate engine kit is the following http://www.summitracing.com/dom/part...l65e/overview/ and I installed all stock with the exception of the air filter.
Thanks!

With the DBW, if the engine is not running, I don't believe that pressing on the gas pedal actually moves the throttle blades. I believe that the clear flooding mode kicks in with over a 33% of TPS reading.

The fuel pressure is about 60 psi constant. We first installed a pressure regulator (vaccum referenced) and after reading some posts and GM info, we removed it and installed this http://www.summitracing.com/int/part...3737/overview/.
