the silverado wont run by itself unless fuel pressure is at least 55-60psi at start up, you'll need to change out the fuel pump. This job isn't as hard as you think. Easy way to do it is call a friend or two and remove the bed. The bed is held on by 3 bolts on each side and behind the rear bumper under the bed is some wiring you need to unplug, you'll also have to loosen up the fuel filler neck and ground strap

How to determine if fuel pump is working on 1988 Pontiac 6000.?
Get a can of throttle body cleaner.....spray throttle body cleaner into the throttle body.....open the blade and shoot some into the throttle body. Then try to start the car...if it starts, then you have a fuel delivery problem. Hook a fuel pressure gauge to the fuel rail and just turn the key on and see what pressure you get. If no pressure then it is either your fuel pump OR a clogged fuel filter. You can then put a new fuel filter on, test the pressure again and if still no pressure, you are pretty much looking at the fuel pump. If you get fuel pressure at the fuel rail and it still won't start then you probably have an injector problem.
Why would you have to spray starter fluid in the throttle body for car to start up?
Not enough fuel is reaching the throttle body, check your fuel pressure it may be your pump going out.
Ran Chevy silverado out of gas won't start now?
is it carburated or throttle body injected? try putting a little gas in the carburetor or throttle body or if you have no gas try starting fluid but if you have gas in a jug use that because starting fluid is hard on the pistons and valves. and see if itll start

Why does my 1992 Chevy silverado K1500 350 crank but doesnt start?
There is a fuel pressure test port right behind the throttle body. Borrow, rent or buy a fuel pressure gauge and see if the fuel pressure is building. If not, fuel pump failure is common after the vehicle gets a few miles on it. You could TRY the filter but that's probably not the problem. If you're building pressure, run a computer diagnostic to see if the computer has detected a problem.
