There is no such thing as an underhood wiring diagram. Wiring diagrams are grouped by SYSTEM, not location. So you'd have to get separate wiring diagrams for the charging, fuel injectors, sensors, lights, etc. Even then it's difficult to get the exact diagram. Read this post on what's involvled.

Hi Steve,
Try search terms "GMC Sierra 1500 wiring diagram". This should yield a good few hits like: Schematic me Free Electronic Schematic Diagram and. http://fuel-saver.org/

Schematic?
WELL, if it is a gasoline engine (you did not specify), there isn't much to the "fuel system..." only a single line with one or two pumps routing fuel to the fuel pressure regulator, and a single fuel line from the fuel pressure regulator routing bypass fuel back to the tank. Oh... and the fuel rail and injectors, which are all connected to the fuel pressure regulator.
If it is a diesel engine, it is even simpler!
Why would you need a diagram??

the 1992 , has 2 engine choices.
one is MPI 16v G16B engine
and the other is the G16A 8V, TBI SYSTEM.
diagram, (fuel or electrical?)
its EFI so has both.
here is page that shows both on one, page
do tell engine and exact need and we do have it.
see bottom of this page, ?

for electr,
use search there,
enter "schematics" no quotes

You can access this info here, but we do not have it due to copyrighted material by GM

Due to copy-write laws it is often not possible to post schematics to a public forum such as FixYa.

Subaru have a tech web site you can access for a small fee or go to ALL DATA.com and purchase a subscription for your car. You will find all you need in diagrams, torque spec's, schematics, recalls, tech bulletins etc.

If you know a local independent shop well, they may print you a copy of what you need from their data base system.
