Running way lean!!!

[Turbo Nicky]

I have a 90 gs eclipse. No special mods badically stock just a bov 2g mass air, msd wires, egk plugs, walboro fuel pump, and aftermarket boost gauge. I cannot give the car any throttle without the fuel cutting and it sputters and I get no boost. I replaced almost everythingh including the tps sensor because the throttle body way not opening all the way. Still running lean, the car throws no codes and I get no check engine light. I have had this problem for about 2 months and I have everyone including myself confused. It is not a boost leak I am set on a fuel problem but I am lost. Any help would be appreciated, thank you.

That is your problem right there. Unless you have 550's there is no way you can run the 2g MAS without fuel control. Put back on your stock one, I am guessing it will run alot better.

thanks for replies but I am going to check the whole fuel system. I am convinced that there is a bug somewhere in the fuel system.

wow fuel tank was rusted from the inside and sock on the fuel pump was clogged with muddy, rusty fuel, no fuel was being pumped through the car. Wow problem hopefully fixed tomorrow when I put the new tank in.
