no fuel ......

[dr. tahoe]

my 2000 Tahoe 5.3 does not start, because there is no fuel supply .....
the fuel pump relay is fine
so I took the fuel tank out to test if the fuel pump is the problem
there are 2 electrical plugs - where can I find the description of the wires ?
I have the original GM shop manuals (set of 4), but I don´t find the information ....

thank you very much
Mike

Its the 4 plug connector the other is for the fuel tank pressure sensor, on the 4 plug connector the bigger black wire is the ground and the gray wire is the power for the fuel pump
