Yes you will need to remove the upper plenum to get at it. It is fairly straight forward and will require a basic set of tools (mostly a 10mm socket short and deep, a couple extensions, a swivel, and a ratchet). It should take you about an hour to remove the plenum to gain access to the CPI (central port injection) unit.

My GMC Silverado 1500 will start but wont stay running

You didn't state what year your truck is... I have a 2000 GMC SIERRA which gave me trouble.. would not start until 2nd or 3rd try.. You are probably having trouble with the fuel injectors.The fuel injectors are located beneath the air intake plenum... Not a hard job to do your self. Took me a couple of hours. The plenum is located under what resembles the carburetor..I went around and around for about 2 years , and finally replaced the fuel injector spider. And what a relief. Problem solved... I found the injectors online for under 200..Be patient..And GOD BLESS !

Installed new spider injector. 1999 yukon 5.7 - now plenum vacuum leak I believe. It has a high pitched squeal when started and stops the second I shut it off. what is the torque sequence for the upper...

tightening a plenum in a clockwise..or counterclockwise, pattern is inviting a leak,,.. Start with one corner,,just snug it down.. go to the opposite corner and snug go 90* and snug it,, and go opposite and snug go 90* and tighten it to correct torque spec..(repeat the above process and tighten all the way).. I would use ALL NEW gaskets, and spray a light coat with this on each side,,

Know if my 95 chevy blazer has a spider CPI?

A spider injector is located underneath the intake plenum and this is multi-port. Otherwise you have a throttle body injector system. Vortec engines have spider injectors and they are super expensive to replace ($400.00- 850.00) each ! There is only one spider injector for each engine it has 6 legs/fuel tubes that go to each cylinder.

Replacing the o rings on a 95 chevy s10 2.2

The Injectors are right there in opening of the throttle body. There are not individual injectors for each cylinder.
There 2 or 4 injectors that spray the gas right on top the throttle plate. The entire manifold is filled with the gas/air mixture.

If it's fuel injected, 96 up it will be under the upper plenum of the intake manifold mounted on the side of the injector spider.
