Fuel injecter fuse blow imeditaly when ignition turn on

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.

Brake shimmy is due to hot spots on the rotor or drum the metal is actually hardened in the spots causing friction differences when the brakes are applied causing front end to shimmy .

On my 1991 chevy truck, the transmission will not shift on time

No...but check to see if there is a vacuum modulator on the right side of the unit. If you have one, remove the hose, loosen the clamp and turn it so the line fitting points down, then tap on it. If fluid comes out, replace it. Also check that throttle cable going to linkage is adjusted properly.

IN cluster wiring the earth wire is incorporated in the plugs and is normally plain black. It stays in the harness until it reaches a point where it can be earthed out as most dashes are plastic and will not pass current. A wiring diagram will how where it earths out.

Starting problem

It sound to me like the starter is getting saturated with heat. But that’s just me I would add a heat shield to help or even wrap the starter in Kevlar.
