Found the problem to be that one of the fuel injector positive leads in the TBI was pinched by the metal cover under the air cleaner when it was tighten down. This caused a direct short to ground.

A wire or component in the ecm1 circuit is shorting to ground.

Can someone help with a 1998 Chevy Silverado 4X4 1 ton that will not start at all no spark and not getting fuel tried switching the coil timing gear and chain Motor tries to turn over but will not fir?

Not sure what you did to try to fix it, but sounds like bad ignition module to me. answer you're not getting fuel? did you try checking your fuel pressure? maybe its your fuel pump? did you remember to put the reluctor ring back on ? is your ecm1 fuse blown did you set the engine at tdc before replacing the timing gear set? and if so you should of rotated crank 360 degrees before installin gear set
