Default no start - Car won't start unless I unplug injectors

Car won't start. I get no fuel on my y8 and when I unplug my injectors it fruns for a few seconds then dies.

I installed a b16a2 today and same problem. Car won't start unless I unplug injectors but it dies in a few seconds. Help me please.

Unplug your injectors? The four clips above the injectors? Does your fuel pump prime when you turn the key to the ONII position?

Yes the fuel pumps and turns over but won't run. And when I unplug the injectors (four clips) it runs but I flood the engine and it dies. I thinking that when the in injectors are in it doesn't let the fuel out. So what controls the injectors to shot fuel? It's can be the ecu cause the b16a2 was just running when I took it out of the crashed Si.

You MUST provide all pertinent information about your car and engine. Failure to do so may result in thread closure.

Bad fuel pressure regulator, bad ECU not able to tell the injectors when to fire, or worn out injectors leaking too much fuel

Agreed!...when u unplug the injectors you cut fuel supply...if your engine is flooding with fuel, it will start all of a sudden on the fuel that is in the combustion chamber....if they are plugged in...it is dumping more than recomended fuel
