New Engine No Start Prob

[AntixTSi]

Ok, I'm sitting in my shop now and I just finished putting a fresh engine in my new 90 TSi daily driver. The engine is slightly built but my problem is that when I put the key in the fuel pump wont prime at all. If i cross the test circuit the pump runs and sends fuel, but i dont get a pressure reading on my guage. I have good spark, but if i cross the circuit and try to start it, it still wont start. The mpi fuse is good, and so is the relay. The pump is a walbro 255 from buschur, stock 450's, OBX AFPR, PRofec B Spec 2, very hacked mass, big 16g, etc... Any help would be apreciated. The car drove in, I know its something simple somthing i'm overlooking cause i'm frustrated. Thanks,
-Mark

are your oil pressure senders hooked up? no oil pressure signal, ECU kills FP signal.
Other then that it is running down wires and schematics.

Found the problem. Fuel feed line was backing up...
