MAT (Actually IAT on a stock set-up ) goes in the C11 slot (tan wire).
Print this out. It will help a lot!
ECM Connectors

FYI; IAT sensor will not cause an injector firing issue. It will just set a code.

Glad you got it running. . . . . Short on ground?
Please clarify.

FWIW;
The ground cables are located under the AC compressor. There is one bolt with all the gronds.

thanks for awnsering back,i already checked the ground wires under the ac compressor but they seem to be ok,the only way the injectors work is if i put ground on one of the wires,i made a new tread so you can look at the pic if it helps,thanks jerry.
