i was told i dont have enuf pressure. and that the fuel is basicly leaking out since the injectores arent pressurized. also i dont have the safc tuned its all stock.
i heard the ecu is only sending the amount of fule to pressureize the stock injectors. sooo..... im just talking. anyhting else?

If you haven't changed the fuel pressure from stock then thats simply not the case. Injectors don't start 'dripping' until very low fuel pressures, it depends on the injector, but somewhere around 20psi. Your stock fuel pump will provide more than enough flow at idle. At high rpm and boosting you could have problems with flow on the stock pump. I.e. if it doesn't flow enough under these conditions the fuel pressure will drop and cause a lean condition.

Just try turning down the SAFC in the low throttle map at 1000rpm. Turn it down to -20% and see if it will start. You're not going to hurt anything by doing this and it could answer many questions about whats going on.

hey man i did what u said it idles now just fine i just needed to lean it out.
well u Possitive i need a 2 bar sensor.. jwalk has his 5sfe done with out one.
an i got the safc. s o figured i could just use that.
