Possible you have a huge vacuum leak somewhere, if you start the car and hold the rpms high will it stay running and then die as soon as you let off on the gas.

But really, figure out what failed exactly before you start replacing things. Could be several simple causes.

Walbro pump, fuel rail, pressure regulator/gauge, return line, no more fuel problems.

Haha, I tried to correct the problem for 45mins on the side of the highway haha... and no, I already check that possibility haha

Wide open throttle or not it is diying anyways, the only time I can hold it a very little is when I see gas on my air fuel. But it always stall, and stick hard to the lean side... :P

Try the bypass connector for your FIC to see if the injector outputs are bad.

I tried, it was in my 45mins tryouts lol :P

I completely removed my plug&play harness, right now it is only the OEM ecm controling the engine. I also removed all power supply for 15mins before restarting the engine to let the ecm refresh... no chances...

The engine doesnt even idle at all... it stall way before, I cannot get a stable rpm at all.
